Why CMU should run on a different clock than WDOG? Why CMU should run on a different clock than WDOG? The chip I use is S32K1xx. This is what the Reference Manual says: Re: Why CMU should run on a different clock than WDOG? Got it. Thank you. Re: Why CMU should run on a different clock than WDOG? Hi, the reason is simple: if clock of CMU fails, the watchdog resets application (because is running on another clock) - assuming that CMU's reset is the safe state. Next actions depend on supervisor system. If CMU and watchdog share the same clock, the application got stuck during clock malfunction. Best regards, Pavel

S32K312 Flexcan CANFD mode setting CAN filter problem Excuse me: S32K312 Flexcan CANFD mode to set the CAN filter function FlexCAN_Ip_ConfigRxMb(INST_FLEXCAN_0, RX_MB_IDX_0, &rx_info, 0x55) With this setting, can only the message with ID 0x55 be received? If this function is used to set the filter, how can we receive multiple specific messages (such as ID=0x35, ID=0x68, ID=0x123)? Thanks! Re: S32K312 Flexcan CANFD模式下 设置 CAN filter问题 Hi@Bert2023 "FlexCAN_Ip_ConfigRxMb(INST_FLEXCAN_0, RX_MB_IDX_0, &rx_info, 0x55)"这个函数并不设置filiter,如果你没有设置过filiter，那么默认是每个MB对设置的ID进行所有的比对。 简单来讲，如果你需要设置ID=0x35，ID=0x68，ID=0x123的接收报文，且默认不配置mask,那么你需要为每个ID设置一个MB： FlexCAN_Ip_ConfigRxMb(INST_FLEXCAN_0, RX_MB_IDX_0, &rx_info, 0x35)； FlexCAN_Ip_ConfigRxMb(INST_FLEXCAN_0, RX_MB_IDX_1, &rx_info, 0x68)； FlexCAN_Ip_ConfigRxMb(INST_FLEXCAN_0, RX_MB_IDX_2, &rx_info, 0x123)；

imx8mp gpio读取两个等待状态 我注意到，当使用 Linux /sys/class/gpio 接口时，我的一个输入 gpios 偶尔会从 0 切换到 1。输入始终保持低位，但大约每隔 5 分钟输入就会切换到 1，然后立即切换回。我每 500 毫秒执行一次读取（cat /sys/class/gpio77/value）。 查阅文档后，我注意到 i.MX 8M Plus 应用处理器参考手册 (Rev2, 02/2024) 第 8.3.5.1.2.2 节中有这样一句话： “如果清除了给定的 GPIO 方向位，则读取 DR 寄存器反映相应信号的值。在 进行同步的读取访问。” 这是指什么等待状态？ 这可能是我看到的切换的原因吗？ 谢谢！ 院长 回复：imx8mp gpio读取两个等待状态 关于等待状态的问题已在之前的帖子中得到解答： https://community.nxp.com/t5/i-MX-Processors/GPIO-wait-states/mp/356880

Runtime error 216 at 564BA7AE Dear NXP, I am using MBDT 1.4.0 and NXP S32K312EVB-Q172. Previously, everything worked fine for programming, but suddenly I am unable to perform any actions with the development board. I am using the example "s32k3xx_dio_s32ct" and have confirmed that the hardware is configured as s32k312-Q172. I also verified that the 12V power supply is connected and the OpenSDA driver is functioning correctly. However, I am encountering an error message as shown in the image, and the programming process is interrupted. What could be the cause of this issue? How can I resolve it? Please help me, thanks. MBDT S32K312EVB-Q172  Re: Runtime error 216 at 564BA7AE I resolved the issue by shortening the path of my toolbox.

NCJ29D6 Problems after upgrading to new Firmware Hello, After upgrading the board to a new firmware and adapting the application (APP_INFO, new SDK/API), the device remains in HostIF BKP (0x401504 bkpt 0xFF). Flashing the application was initially possible. Debugging (SWD) works, but I get an exception when I try to call NDP functions (debugger only shows ?? for this memory). Re-flashing with Lauterbach script is now also not possible (the memory for the flash driver also shows ??). But I can still attach and debug the currently flashed application. My guess is that the new application cannot be found and the device has now activated SWUP? I'm not quite sure why flashing the new application didn't work and how I should proceed from here? Best regards, Stefan Re: NCJ29D6 Problems after upgrading to new Firmware Hello, Hope you are doing well. Sorry for the inconvenience this might cause you but as the information of this product it's under NDA (Non-Disclosure Agreement) the information it's not public.

S32G3 BSP41 PFE2 RGMII to RGMII without PHY on the customized board Hi, Our hardware design connects PFE2 RGMII directly to the switch RGMII without a PHY. The PFE2 is configured with rgmii-id, and we have verified the 125MHz TX clock output. I have come across discussions suggesting the use of a common external clock for both sides. Is clock drifting the only concern in this setup? If so, is it possible to configure PFE2 as a clock slave and use the clock output from the switch to synchronize TX and RX? Thanks, XD Re: S32G3 BSP41 PFE2 RGMII to RGMII without PHY on the customized board Hello @XD, I am glad you found the information helpful. Thanks for accepting my answer as a solution.

Thanks, XD Re: S32G3 BSP41 PFE2 RGMII to RGMII without PHY on the customized board Hello @XD, To the best of my knowledge the same guidelines should apply to any device connected using RGMII, either a PHY or a switch.  with that said, can you share the RGMII device you are connecting the S32G3 to? So I can check if there could be special considerations. Thanks in advance. Re: S32G3 BSP41 PFE2 RGMII to RGMII without PHY on the customized board Hi @alejandro_e , It's great that you're helping me again—I really appreciate it. The guideline you provided is for an RGMII-to-PHY scenario. Do you have any guidelines for a direct RGMII-to-RGMII connection without a PHY? Thanks, XD Re: S32G3 BSP41 PFE2 RGMII to RGMII without PHY on the customized board Hello @XD, It is good to support you again.

How to obtain the commutation timing sequence table? Hello all:     I am testing the BLDC using the MCSPTE1 AK144 kit.      When I was reading the AN12435.pdf, I saw the Figure 4 "Six-step switching sequence" of page 5, and please refer to the attached sequence.png file.     I want to know how this switching sequence is obtained? What method can be used to obtain the sequence?     Thanks! Best regards, Fedora Re: How to obtain the commutation timing sequence table? Hello Leo:    Ok, I understand now. I will continue my research. Thanks for your help. Best regards, Fedora Re: How to obtain the commutation timing sequence table? Hi, Thank you so much for your interest in our products and for using our community. You could refer to Figure 2. 3-phase BEMF voltages and phase currents of a BLDC motor from the same app note. On the other hand, Six-step commutation is a very common method for driving a 3-phase star-connected BLDC motor, maybe there are more detailed documentation about this on the web. We usually just describe the basics to implement motor control with our MCUs. Hope it helps you. Have a nice day!

How do RFLevel values change the sensitivity of the RF Level Detector on the PN512? Increasing the RFLevel increases the V~Rx [Vpp] based on the table 155 in the pn512 datasheet. What does that mean in terms of sensitivity for the RF Level Detector? Does raising the V~Rx[Vpp] mean I am increasing sensitivity?  Does increasing RFLevel increase the gain for some kind of amplifier thereby increasing the sensitivity or is it raising some type of threshold thereby decreasing the sensitivity?  Thank you NFC Frontend Solutions Re: How do RFLevel values change the sensitivity of the RF Level Detector on the PN512? Hi, Sensitivity should increase as RF level value goes from 0xF to 0x0. Regards, Eduardo. Re: How do RFLevel values change the sensitivity of the RF Level Detector on the PN512? Thank you for your reply. So as RFLevel increases from 0x00 to 0x0F I am increasing the sensitivity of the RFLevel Detector? Or is it the other way around where the sensitivity of the RFLevel Detector is increasing as RFLevel goes from 0x0F to 0x00. Thank you Re: How do RFLevel values change the sensitivity of the RF Level Detector on the PN512? Hello @user_leo Hope you are doing well. The RF level detector detects the presence of an external RF-field delivered by the antenna to the RX pin. The values listed in Table 155 should correspond to a typical voltage that would be seen at the RX pin. However, the sensitivity itself depends on the antenna configuration and tuning. Lower sensitivities are prone to intrinsic noise in the environment, causing misleading results. To increase the sensitivity of the RF level detector an amplifier can be activated by setting the bit RFLevelAmp, but it would be recommended to use it with upper values. Regards, Eduardo.

IMX8QM DP++ (DisplayPort Dual-Mode) Hi, We've a custom (imx8qm) board with an mDP (mini DisplayPort) connector, and I'd like to connect an external HDMI screen using a passive mDP-HDMI adapter. My understanding is that this should be possible if DP++ (DisplayPort Dual-Mode) is supported. I have a few questions regarding DP++ support on the i.MX8QM: i.MX8QM DP++ Support: Does the i.MX8QM processor itself support DP++? Cadence Firmware DP++ Support: Does the Cadence firmware for the i.MX8QM's DisplayPort controller support DP++? Device Tree Configuration: Are there any necessary device tree (dtb) configurations required to enable and utilize DP++ functionality? If so, could you please provide details on the specific settings? Thank you for your assistance. Re: IMX8QM DP++ (DisplayPort Dual-Mode) Hello, Unfortunately DisplayPort Dual-Mode is not supported in i.MX8QM, you need to look into another adapter. I apologize the inconvenience that this may affect your design. Best regards.

What does it mean HSE_SWT_RST on S32K311!!! Hello all. Where can I found information about HSE_SWT_RST reset? With the following clock configuration: PLL_PHI0_CLK=120MHz CORE_CLK=PLL_PHI0_CLK/1=120MHz AIPS_PLAT_CLK=PLL_PHI0_CLK/2=60MHz AIPS_SLOW_CLK=PLL_PHI0_CLK/4=30MHz HSE_CLK=PLL_PHI0_CLK/1=120MHz DCM_CLK=PLL_PHI0_CLK/4=30MHz at power on I occasionally get the reset HSE_SWT_RST. What is the cause? I probably need to reduce the HSE clock to 60 MHz or change the value of HSE_CLK_MODE_AND_GSKT_CTRL to 10 of the dcf_client_utest_misc client. Where can I find documentation that explains this? Best regards E. Re: What does it mean HSE_SWT_RST on S32K311!!! Hi @enricoantonioli  The HSE_SWT_RST is usually caused by wrong clock configuration. It was found out that it is possible to configure 120MHz HSE_CLK only during reset by DCF record. It cannot be done later by software for some reasons. That means it is necessary to set PLL_ENABLE in BCW (Boot Configuration Word) in IVT, it is necessary to program crystal oscillator configuration flag in UTEST at 0x1B000050 (see section 32.4.3.2 Crystal oscillator configuration flag in the S32K3 RM), it is necessary to program the dcf_client_utest_misc - HSE_CLK_MODE_AND_GSKT_CTRL equal to 10 or 11. Re: What does it mean HSE_SWT_RST on S32K311!!! Hi, Thanks for the precious information, but I still don't understand why in my situation there is a HSE_SWT_RST reset. What is the cause? What's wrong with the HSE? Best regards E. Re: What does it mean HSE_SWT_RST on S32K311!!! Hi @enricoantonioli  What does HSE_SWT_RST mean? It stands for HSE Software Watchdog Timer Reset. Is it a reset due to an internal HSE watchdog or what? The HSE CPU is mainly composed of Arm Cortex-M0+, which one of its essential peripherals is the watchdog.  So yes, it is trigger by HSE SWT as the name implies. Why this reset occurs if no firmware is programmed into the HSE memory? The HSE CPU, even if the HSE firmware is not loaded, is active because it contains the SBAF code. Re: What does it mean HSE_SWT_RST on S32K311!!! HI Vane, first of all, thank you very much for your quick reply. At the moment I have reduced the HSE_CLOCK to 60 MHz because in the HSE there isn't programmed a firmware. I will activate HSE soon. What does HSE_SWT_RST mean? Is it a reset due to an internal HSE watchdog or what? What I don't understand is why this reset occurs if no firmware is programmed into the HSE memory? If I understand correctly, at power on the HSE processor executes the SBAF code and then stops in a WFI. So who triggers the HSE_SWT_RST reset? Best regards E. Re: What does it mean HSE_SWT_RST on S32K311!!! Hi @enricoantonioli  According to the information, it seems that the problem is due to incorrect clock configuration. The HSE_CLK_MODE_AND_GSKT_CTRL (bit 30-29) must be set to 1x if you want to use HSE_CLK equal to 120 MHZ. On the other hand, if HSE_CLK_MODE_AND_GSKT_CTRL was set to 00, it is necessary to change HSE_CLK to 60 MHZ. Refer to S32K3xx_DCF_clients file attached to the S32K3xx Reference Manual.  This must be done by writing to dcf in UTEST memory using Flash controller. You can check the following article, it might be a good reference.  [S32K3] Restrict the debug access with a password when HSE is not used BR,VaneB

3V coin cell backup for imx93 Hello everyone, I would like to know if there is any way to use a 3V Coin Cell battery backup for the NVCC_BBSM_1P8 power rail of the imx93 with the PCA9451A PMIC. As I must keep the RTC and Tampers working once the main supply has been shutted down, a Coin Cell backup is needed. In the "4.1.3 Power architecture" section of the imx93 datasheet there is an image which shows the basic diagram for a backup battery. I wonder if there is a way to connect the 3V CC to the PMIC. In order to achive an uninterrumpted NVCC_BBSM_1P8 (provided by LDO1), I must keep INL1 and VSYS above 2.7V  due to the UVLO feature of the PMIC (which is impossible with a 3V CC). Anyway, a LDO with a CC would be pretty bad in terms of efficiency. Is there any way to use a 3V CC backup alongside the PCA9451A to keep NVCC_BBSM_1P8 power rail on? If no, is a power mux with ideal diodes needed to do a custom switchover between the PMIC's LDO output and a regulated (with a buck converter) 3V coin cell to manage this issue? Best regards, Gorka. Re: 3V coin cell backup for imx93 Hello, As is mentioned in PMIC's datasheet, the suggested option is connect a battery and a regulator in NVCC_BBSM_1P8 power rail to keep this power domain on and switch between the PMIC's LDO and regulated output from coin cell. Best regards.
