P3T1755 Demo   In this space I want to show you the things that you can create usign our products.   In  this demo I demostrate a use case creating a GUI for a Temperature Sensor.   We can create modern GUIs and more with LVGL combined with our powerful processors.               CPU USAGE As we can see  the CPU usage for this demo is around 2%   Pictures         This demo is based on the previous publused articles.   References: https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Adding-support-to-P3T1755-on-Linux/ta-p/1855874 https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/How-to-run-LGVL-on-iMX-using-framebuffer/ta-p/1853768  

In L2.6.35_11.09.01_ER BSP Uboot, the MMC driver was updated, but there is issue that when you modified some uboot code, the MMC driver has chance to fail to work. The root cause is that mmc->has_init hasn't been initialized. Sometimes the value will be not zero, then mmc driver will be skipped for initialization. Attached is the patch to fix this issue in L2.6.35_11.09.01_ER BSP Uboot.

Question: Did we tested active PCIe components while the Cortex-A9 was in Sleep Mode (suspend to memory)? Answer: It's a known issue that PCIe can't support suspend/resume. And can't be built in kernel image if the system want suspend/resume. I think PCIe will be active while core is in sleep more. Is it different scenario? No, the pcie core is not active, it is in L2 state after suspend, and it can't resume back to L0 state when system resume is called. So, DO NOT let pcie do suspend operation right now. BTW, the tested device: * INTEL x1 1000M CT network card. * INTEL iwl wifi cards. * x1 pcie to usb3.0 card Yes, this patch had been tested on imx_3.0.35_4.0 release, and would be merged into next 3.0.35 release. TO1.2 is used. We tested the Patch against imx_3.0.35_4.0 release

The patch is based on jb4.3_1.1.1-ga_rc2. Merge some commits from kitkat.

Tested in FRDM-i.MX91 Written in C LF-6.12.49

Q: Does VIN have to be valid before we can talk to the PMIC over i2c? Can a valid voltage on LICELL and VDDIO work instead? The PF0100 datasheet says: ---------------------------------------------- To communicate with I2C, VIN must be valid and VDDIO, to which SDA and SCL are pulled up, must be powered by a 1.7 to 3.6V supply. VIN, or the coin cell voltage must be valid to maintain the contents of the registers. -------------------------------- A: VIN and VDDIO must be valid for communicating to the I2C block. Having LICELL and VDDIO will not work since a portion of the digital circuitry needed for accessing the registers is powered through VIN. This document was generated from the following discussion: Programming PMIC over i2c

Why reset EPDC When TCE underrun occurs repeatedly, EPDC might lock up and the signal to panel continues. There is chance to cause panel damage. The attached patch provides a way to reset EPDC to cut the signal out and recover EPDC from lockup. The patch is based on L4.1.15. As for TCE underrun, QoS patch has obvious improvement. https://community.nxp.com/docs/DOC-343599

Garz & Fricke product SANTARO will be displayed on the Freescale booth during the upcoming embedded world in Nuremberg. SANTARO is using the Freescale iMX6 processor. Single-, dual and quadcore.

Sometimes there is a requirement to make display work in portrait mode when physical panel is in landscap mode. setprop persist.demo.rotationlock true setprop persist.demo.remoterotation portrait The above codes can be set in init.rc to take effect when android boot up.

I was trying to implement an E-Ink solution using IMX7D. Unfortunately I only had a IMXEBOOKDC3 available, not the DC4 shown on the IMX7D E-Ink tutorials. After a couple of tries I found the right way of connecting the expansion board and the the definition of the arguments on U-boot to make the IMX7D and DC3 work together.  I logged these considerations on the blog post below: http://bit.ly/IMX7D_IMXEBOOKDC3   Andres

Dear All,       Our board is designed based on both EVK and HEG (Adeneo Embedded Home Energy Gateway), the ENET_FEC_RESET_B on EVK is replaced by LCD_D11 as it on HEG. We have re-config all pins based on i.mx28 BSP and successfully built by ltib. However, eth0 is not working due to "PHY is not found"! and we are still trying to figure it out.       The changes we apply on the BSP are(in mx28evk_pins.c): in static struct pin_desc mx28evk_fixed_pins[]:       the definition of LCD_D11 change to { .name = "LCD_D11", .id = PINID_LCD_D11, /* PHY reset pin*/ .fun = PIN_GPIO,      .voltage    = PAD_3_3V,      .strength = PAD_8MA,      .output     = 0, },      and replace all "PINID_ENET0_RX_CLK" in mx28evk_pins.c by "PINID_LCD_D11"      To prevent any possible interrupt, we also disable all LCD pins in both mx28_pins.h and mx28evk_pins.c since we don't have LCD.      Any comment/suggestion is highly appreciate! BR, TF
