I'm bringing up a custom STM32MP15x-based design, and I'm encountering what looks like stack corruption issues in U-Boot (and I can't get a kernel to boot).Symptoms:I've enabled early debug printing, and get the following output:U-Boot SPL 2020.04-st...
Hi all.The en.MB1272-DK2-C01_Schematic.pdf states thatARD_A0 : PF14 -> ADC1_IN0ARD_A1 : PF13 -> ADC1_IN1ARD_A2 : ANA0 -> ADC2_IN6ARD_A3 : ANA1 -> ADC2_IN2I've spend quite some time to figure out that this is wrong and the correct pinout is:ARD_A0...
Hello everyone, I would like to connect the stm32mp157c-dk2 card with the wm8960 audio codec,here is the device tree configuration I made./* sound card*/ snd_i2s2: snd_i2s2 { compatible = "audio-graph-card"; widgets = ...
Hello,I have been trying to work with the BSEC and write some data to the upper OTPs, where I managed to successfully write only to the words containing the MAC address. Then I realised, that the device tree needs to be modified to allow other OTP wo...
Hello everyone.I am modifying the distribution packages of 157C-DK2 and 157C-EV1 for my project.When I previously configured my rootfs using buildroot and debian-jessie, I proceeded as follows(other boards).Packages that can be configured using bui...
Dear all, I am looking to use the STPMIC1 in one new STM32MP15x design which will spend most of this time in standby mode. I am looking for STPMIC1 buck efficiency at light load (~1mA). In the datasheet there is numbers only for 150mA, 750mA and 1A. ...
Hello!We have a problem of LCD image quality with our custom STM32MP157C-based board: we see artefacts, wrong colours, ghosts of previous images and rainbows. The LCD is a Winstar WF40CTYAQM, linked with MIPI DSI, much like the Orise Tech LCD of the ...
Hi all,i am trying to interface es8388 to I2S3 bus,Here are fragments from device tree : sound { compatible = "audio-graph-card"; label = "STM32MP1-SOM"; routing = "Playbac...
I have a new STM32MP157C-DK2, it stops (hangs) very often.Especially when I run a demo.The 3D GPU demo runs no longer than 30 seconds.The Video playback doesn't finish mostly and then the system crashes again.Is this a known problem. Are there update...
I'm currently working with the Seed STM32MP1 SoM which has STPMIC1 attached to I2C2. I've been working on setting up a device tree for it, but I've been hitting some bugs. When booting the mainline ATF with my device tree (modified DK2 board, just wi...
