Question: LVDS in split mode (dual lvds) is used. In this configuration, only LVDS0_CLK is used. What is the suggestion for the LVDS1_CLK?  The HW user guide says that if this is unused, then to leave it floating.  Would we also suggest the same for this case or would termination be more appropriate?  Or is there some possible way to gate this clock?  (if so, it isn't obvious in the RM) Answer: According to the MX6 Developer's Guide, any unused LVDS pins should be left floating, so the LVDS1_CLK pair, in this case should be left floating. In order to minimize any potential EMC, the lands for those balls should not have any additional traces leading away. To add a bit more information, the customer ran some tests and found that the clock gate bits for the LVDS1 are essentially ignored in Dual mode.  The only way to disable it is if they are both disabled which is not helpful in this case.  It seems that the Dual mode setting overrides the CG.

LSIO_GPIO0_IO0x toggling on i.MX8QM Issue customer met: Customer met LSIO_GPIO0_IO0x not toggling on i.MX8QM, they are working through the software on their board, part of that involves getting a few GPIO pins working. They have been using several GPIO pins for a while now, we have some simple toggles and some others where we bit bang i2c, all of those have worked fine. However, They have not been able to get 3 pins to either read or set successfully at all: LSIO_GPIO0_IO00 (SIM0_CLK) LSIO_GPIO0_IO01 (SIM0_RST) LSIO_GPIO0_IO02 (SIM0_IO) 1\ Reproduce on our i.MX8QM EVK board  a. Check the hardware connection Check the LSIO_GPIO0_IO00 (SIM0_CLK), LSIO_GPIO0_IO01 (SIM0_RST) and LSIO_GPIO0_IO02 (SIM0_IO) connection in our i.MX8QM EVK board. In the default design in NXP i.MX8QM EVK board, the pins SIM0_CLK, SIM0_RST and SIM0_IO connect to the SIM CARD on the base board.         b. To make these pins work as GPIO pins In the default pins mux, default pins mux on the SIM0, to make these pins work as GPIO, need to mux them to the GPIO functions. SIM0_CLK (SIM0_CLK)     SIM0_RST (SIM0_RST)   SIM0_IO (SIM0_IO)     c. In the source code change these pins mux to GPIO configuration: Defalt setting for these pins : linux-imx/arch/arm64/boot/dts/freescale/imx8qm-mek.dts at lf-6.12.y · nxp-imx/linux-imx · GitHub   pinctrl_sim0: sim0grp {                              fsl,pins = <                                            IMX8QM_SIM0_CLK_DMA_SIM0_CLK           0xc0000021                                            IMX8QM_SIM0_IO_DMA_SIM0_IO                 0xc2000021                                            IMX8QM_SIM0_PD_DMA_SIM0_PD               0xc0000021                                           IMX8QM_SIM0_POWER_EN_DMA_SIM0_POWER_EN                         0xc0000021                                            IMX8QM_SIM0_RST_DMA_SIM0_RST            0xc0000021                              >;               }; Linux dts should set them to GPIO0 functions:               IMX8QM_SIM0_CLK_LSIO_GPIO0_IO00 0xc0000021               IMX8QM_SIM0_RST_LSIO_GPIO0_IO01 0xc2000021               IMX8QM_SIM0_IO_LSIO_GPIO0_IO02 0xc0000021 Build the source code, download the images to board, test on the SIM pins to see if these pins can work or not. Test on the J45 pins 3,5,6.   Test the SIM_CLK as an example: Test commands in Linux echo 480 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio480/direction #output high echo 1 > /sys/class/gpio/gpio480/value #measure the PINs #output low echo 0 > /sys/class/gpio/gpio480/value #measure the PINs Found these pins can not toggling well. 2\ Go next further test and consideration Foud the SCU_GPIO0_00, SCU_GPIO0_01, SCU_GPIO0_02 are also configurate as GPIO function in the SCFW,  in the default setting for the SC_P_SCU_GPIO0_00is the function GPIO0_00 , and when setting the SIM0_CLK to GPIO0_00 function then the GPIO0_00 can not work normally. So if setting the SIM0_CLK as GPIO0_00 function, then we need to set the SC_P_SCU_GPIO0_00 this PIN to others function, so that no conflict of them. Even no use the pin SC_P_SCU_GPIO0_00 in hardware, we also need to set them to others function to avoid the conflict. SCU_GPIO Pins mux: SCU_GPIO0_00 (SCU_GPIO0_00)   SCU_GPIO0_01 (SCU_GPIO0_01)   SCU_GPIO0_02 (SCU_GPIO0_02)         Tested the PINs "SIM0_CLK, SIM0_IO, SIM0_RST" on iMX8QM MEK with base board. All of them works fine.  The key points are already listed. VDD_SIM0 power should be supplied (It is 3.3V on MEK from PF8100 LDO)   Linux dts should set them to GPIO0 functions:     IMX8QM_SIM0_CLK_LSIO_GPIO0_IO00 0xc0000021     IMX8QM_SIM0_RST_LSIO_GPIO0_IO01 0xc2000021     IMX8QM_SIM0_IO_LSIO_GPIO0_IO02 0xc0000021 The default IOMUX for PINs SC_P_SCU_GPIO0_00, SC_P_SCU_GPIO0_01, SC_P_SCU_GPIO0_02 should be changed from 0 to others.  Test on MEK, we used followed codes in SCFW board_init():     else if (phase == BOOT_PHASE_FINAL_INIT)     {         /* Configure SNVS button for rising edge */         SNVS_ConfigButton(SNVS_DRV_BTN_CONFIG_RISINGEDGE, SC_TRUE);           /* Init PMIC if not already done */         pmic_init();         pad_force_mux(SC_P_SCU_GPIO0_00, 2,             SC_PAD_CONFIG_NORMAL, SC_PAD_ISO_OFF);         pad_force_mux(SC_P_SCU_GPIO0_01, 2,             SC_PAD_CONFIG_NORMAL, SC_PAD_ISO_OFF);         pad_force_mux(SC_P_SCU_GPIO0_02, 2,             SC_PAD_CONFIG_NORMAL, SC_PAD_ISO_OFF);     }  Note: In SCFW, should also set SC_P_SCU_GPIO0_00, SC_P_SCU_GPIO0_01, SC_P_SCU_GPIO0_02 to other functions, because they are set to GPIO0_0x function default, if two PINs set to the same functions, such as SIM0_CLK_DMA pin and SCU_GPIO0_00 pin are set to GPIO0_00 together, the function will not work correctly.   Test commands in LInux: echo 480 > /sys/class/gpio/export echo 481 > /sys/class/gpio/export echo 482 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio480/direction echo out > /sys/class/gpio/gpio481/direction echo out > /sys/class/gpio/gpio482/direction #output high echo 1 > /sys/class/gpio/gpio480/value echo 1 > /sys/class/gpio/gpio481/value echo 1 > /sys/class/gpio/gpio482/value #measure the PINs, they are correct high  ( 3V ) #output low echo 0 > /sys/class/gpio/gpio480/value echo 0 > /sys/class/gpio/gpio481/value echo 0 > /sys/class/gpio/gpio482/value #measure the PINs, they are correct low ( 0V ) The test result is based on real measurement on iMX8QM MEK.    Note: 1\In customer's side If still not work, To confirm the issue, please suggest customer build SCFW with parameter "-m", then use followed commands to dump the IOMUX registers: md 0x41F80000 1 md 0x41F80040 1 md 0x41F80080 1 md 0x41F82140 1 md 0x41F82180 1 md 0x41F83000 1   The "md" command should run from SCFW debug UART, not linux/uboot UART. 2\Make sure the hardware in customer's side VDD_SIM0 power should be supplied .

SW : uboot-imx lf_v2025.04 HW : i.MX 8MP EVK board, Oscilloscope   1. Introduction This guide explains the concept of DDR clock spread spectrum on the i.MX 8MP EVK platform. Note that the official NXP BSP does not enable this feature by default. Additionally, this guide provides an example code patch and verification steps to enable the LPDDR4 clock spread spectrum feature on the NXP i.MX 8MP EVK board.   2. What is Spread Spectrum? Spread Spectrum (SS) is a technique used to reduce electromagnetic interference (EMI) by slightly modulating the clock frequency around its nominal value. Instead of operating at a fixed frequency (e.g., 800 MHz), the clock signal is varied within a small range (e.g., ±0.5%). This modulation spreads the energy of the clock signal over a wider frequency band, reducing the peak energy at any single frequency. In other words, SS does not change the average clock speed significantly, but it helps to distribute the spectral energy, making the system less likely to violate EMI regulations.   3. Why Enable Spread Spectrum on DRAM Clock? Enabling Spread Spectrum on the DRAM clock helps reduce electromagnetic interference (EMI) by slightly modulating the clock frequency, lowering peak emissions and making it easier to meet regulatory standards such as FCC and CE. This approach improves system reliability by minimizing interference with other components, offers a cost-effective alternative to hardware changes like shielding or PCB redesign, and is widely adopted in high-speed interfaces such as DDR, PCIe, and SATA to ensure compliance without additional hardware complexity.   4. Related registers CCM_ANALOG_DRAM_PLL_SSCG_CTRL                             Note :  PLL_MFREQ_CTL[19 : 12] : Value of modulation frequency control The larger the mfr value, the lower the MF value (the slower the modulation); the smaller the mfr value, the higher the MF value. MF : The frequency of spread spectrum modulation is the speed at which the triangular/sawtooth modulated wave travels back and forth once per second, measured in Hz (commonly in the tens of kHz range). The speed of the spread spectrum "jitter" is determined. Usually, around 20–50 kHz is chosen to make the energy "swipe evenly" within the bandwidth of the EMI test receiver, thereby reducing the peak radiation at a certain frequency point. PLL_MRAT_CTL[9 : 4] : Value of modulation rate control The larger mrr is, the larger MR is (the wider the range); similarly, MR is also directly proportional to mfr and inversely proportional to m. MR : Peak-to-peak percentage of spread spectrum (the percentage of the total range of the clock frequency swinging around the center value). For example, MR = 0.5% means that the frequency swings around the center value by a total of 0.5% (if it is center-spread spectrum, it is usually ±0.25%).The MR determines the depth (width) of the spread spectrum. The larger the MR, the wider the spectral energy distribution and the lower the peak value, but it comes at the cost of jitter/timing margin (timing should be carefully selected for DDR, SerDes, etc.). 5. About Uboot code patch. Please refer the attachment patch file. At high DRAM frequency, Enable SS may cause not stable problem. So, in this case, I will choose 2400Mbps data clock run the test. Firstly, we should make sure that our code include the 2400Mbps PLL setting. DRAM data speed is 2400Mbps, the DRAM clock is 1200MHz. So the DDRC PLL clock should set up with 600MHz. For example, refer the below code. static struct imx_int_pll_rate_table imx8mm_fracpll_tbl[] = {     PLL_1443X_RATE(1000000000U, 250, 3, 1, 0),     PLL_1443X_RATE(933000000U, 311, 4, 1, 0),     PLL_1443X_RATE(900000000U, 300, 2, 2, 0),     PLL_1443X_RATE(800000000U, 200, 3, 1, 0),     PLL_1443X_RATE(750000000U, 250, 2, 2, 0),     PLL_1443X_RATE(650000000U, 325, 3, 2, 0),     PLL_1443X_RATE(600000000U, 300, 3, 2, 0), // 2400Mbps     PLL_1443X_RATE(594000000U, 99, 1, 2, 0),     PLL_1443X_RATE(400000000U, 400, 3, 3, 0),     PLL_1443X_RATE(266000000U, 266, 3, 3, 0),     PLL_1443X_RATE(167000000U, 334, 3, 4, 0),     PLL_1443X_RATE(100000000U, 200, 3, 4, 0), }; PLL output calculator formula is : PLL_out = 24MHz*mdiv/pdiv/(2^sdiv) So, 2400MHz * 300 / 3 / 2^2 = 600MHz   6. Test result Non Enable SS Enable SS with 1% MR and Down spread Enable SS with 2% MR and Down spread Enable SS with 2% MR and Center spread

This article describes how to create a tiny rootfs based on BusyBox.   Test platform: i.MX 95 19x19 LPDDR5 EVK. The attached layer can be used with other platforms as well. Software: Linux BSP 6.12.34-2.1.0 Boot device: SD card   This article provides a custom meta-tiny-rootfs layer, to simplify the enablement. The layer: creates a custom distribution based on Poky, with no extra features creates a custom image based on BusyBox that only starts a terminal removes most of the machine features uses musl, instead of glibc   Using the default DISTRO=fsl-imx-wayland and core-image-minimal, the rootfs size is 800MB. Using the custom DISTRO=tiny-rootfs and core-image-tiny, the rootfs size reduces to 2.6MB.   How to? 1. Prepare the Yocto environment according to Section 3, 4, 5 in i.MX Yocto Project User's Guide. In the next commands, we'll assume the Yocto directory is imx-yocto-bsp, and the build directory is build. 2. Configure the build directory: cd ~/imx-yocto-bsp/ DISTRO=fsl-imx-wayland MACHINE=imx95-19x19-lpddr5-evk source ./imx-setup-release.sh -b build Note: The imx-setup-release.sh script accepts only Wayland distributions. We'll set the custom distro at the next step. 3. Set the custom distro. In the build directory, run: echo 'DISTRO = "tiny-rootfs"' >> conf/local.conf 4. Download the meta-tiny-rootfs archive, and extract it into the ~/imx-yocto-bsp/sources directory. cd ~/imx-yocto-bsp/sources tar -xvf meta-tiny-rootfs.tar.gz 5. Add the meta-tiny-rootfs layer to BBLAYERS: cd ~/imx-yocto-bsp/build bitbake-layers add-layer ../sources/meta-tiny-rootfs 6. Build the core-image-tiny image. bitbake core-image-tiny 7. Write the image on an SD card, and boot. You should be able to see a similar log: [ 6.183401] Run /sbin/init as init process init started: BusyBox v1.37.0 () starting pid 163, tty '': '/bin/mount -t proc proc /proc' starting pid 164, tty '': '/bin/mount -t sysfs sysfs /sys' starting pid 165, tty '': '/bin/mount -t devtmpfs devtmpfs /dev' mount: mounting devtmpfs on /dev failed: Resource busy starting pid 166, tty '': '/bin/mount -o remount,rw /' [ 6.246037] EXT4-fs (mmcblk1p2): re-mounted a5abac39-6c11-419f-97ef-86532e2616ad. starting pid 167, tty '': '/bin/mkdir -p /dev/pts' starting pid 168, tty '': '/bin/mount -t devpts devpts /dev/pts' starting pid 169, tty '': '/bin/mount -a' starting pid 170, tty '': '/sbin/swapon -a' starting pid 176, tty '': '/etc/init.d/rcS' starting pid 177, tty '/dev/ttyLP0': '/usr/sbin/ttyrun ttyLP0 /sbin/getty 115200 ttyLP0' Tiny Rootfs Operating System 1.0.0 imx95-19x19-lpddr5-evk /dev/ttyLP0 imx95-19x19-lpddr5-evk login:   How to add additional features?  If you want to add additional features to DISTRO_FEATURES, MACHINE_FEATURES, or IMAGE_FEATURES, please use the DISTRO_TINY_FEATURES, MACHINE_TINY_FEATURES and IMAGE_TINY_FEATURES variables. For example, to add bluetooth to MACHINE_FEATURES, add the following line in conf/local.conf. MACHINE_TINY_FEATURES = "bluetooth"   Note: If you need to add a package that requires the full libc (instead of musl), add the following in conf/local.conf: TCLIBC = "glibc"   These optimizations were inspired by this presentation: Honey, I shrunk the rootfs!

Sorry I can't find a place to share this input file. It is to reproduce the VPU JPEG decoder issue I reported in Corrupted MJPG decoding result with FSL 3.10.17 BSP on i.MX6Q VPU​

The documentation is about to present a detailed build steps to implement the verification of the integrity of the rootfs for i.MX8ULP.

Question: The following contradicting information regarding the UART clock tree has been seen in the Rev. 1.0  version of the reference manual: Page 813: PLL3_PFD1 -> divide by 6 -> adjustable post divider -> UART Page 839: PLL3 -> divide by 6 -> UART In the old Rev D I found: Page 803: PLL3 -> divide by 6  ... and something about 80MHz The assumption is that correct path would be: PLL3 -> divide by 6 -> post divider -> UART. Answer: The designer said that UART _CLK_ROOT comes from PLL3 (not PLL3:PFD1) and is divided by 6 to produce 80 MHz. I'm waiting for him to confirm that the divider he mentions is CSCDR1[UART_CLK_PODF].

Customer requirement: Use NOR boot as a backup — boot from NOR, then mount kernel, DTB, and rootfs from NAND. Test module: https://www.nxp.com/design/design-center/development-boards-and-designs/m2-nand-flash-daughter-card:M2-NAND-FLASH   Test under L6.12.49 Uboot.   1. Why Does U-Boot Source Need Modification on i.MX95? i.MX93's boot ROM initializes the SD3_XXX and SD1_XXX PADs. On the i.MX93 EVK design, SD3_XXX is routed to the M.2 connector, and SD1_XXX is connected to eMMC.   For i.MX95, the boot ROM only initializes the XSPI1_XXX PADs. The FlexSPI signals can be muxed out from SD3_XXX, but the boot ROM cannot boot from SD3_XXX.   Due to these differences, the uboot.bin flashed into NOR must have the ability to read NAND. However, the default BSP always reads from NOR, so U-Boot must be modified to activate the M.2 NAND module. 2. Flashing NAND To flash NAND, a custom UUU script must be used. Using the built-in UUU spinand flashing script is not recommended — the built-in script assumes NAND is accessible in U-Boot, but the default imx-boot uses NOR. 2.1 UUU Script uuu_version 1.2.39 #

then upon entering U-Boot, override the pinctrl settings in the DTB so that the FlexSPI driver uses the NAND pins, and then bring up the NAND on the M.2 connector during U-Boot initialization. imx95_19x19_evk_spinand_defconfig is based on the FSPI defconfig with MTD NAND configuration enabled in U-Boot. diff --git a/arch/arm/dts/imx95-19x19-evk-u-boot.dtsi b/arch/arm/dts/imx95-19x19-evk-u-boot.dtsi index 3c0c2d7b0f2..0d8fb0c3978 100644 --- a/arch/arm/dts/imx95-19x19-evk-u-boot.dtsi +++ b/arch/arm/dts/imx95-19x19-evk-u-boot.dtsi @@ -182,3 +182,7 @@ assigned-clock-parents = <0>, <&scmi_clk IMX95_CLK_HSIOPLL_VCO>, <&scmi_clk IMX95_CLK_SYSPLL1_PFD1_DIV2>;
