Hello,I would like to embark on a project for a custom board with the STM32MP157DAB1 and I am referencing the STM32MP15-DISCO schematic from ST which uses the STM32MP157CAC3.My Question: How do I translate between the functionality of the pins?From o...
Hello,We are using the LBEE5KL1DX-883 WLAN+BT chip with a STM32MP157C on a custom board. The SDIO interface is routed to the SDMMC3 interface (different from the DK-2 board). However when we are probing the brcmfmac module, it cannot find the mmc0 in...
Hello,we are bringing-up our custom STM32MP157AAB3 board and we are facing some errors in linux with the uSD that it's connected to the SDMMC1 interface.Here follows our setup:HWSDMMC1 cabled to a uSD connector, PE9 used as card detectSDMMC2 cabled ...
Hi!During loading flash_layout image to custom STM32MP1 I've got following error after staring u-boot and truing to load information to partition 0x04 fsbl1:U-Boot 2020.01-stm32mp-r1 (Jan 06 2020 - 20:56:31 +0000)CPU: STM32MP157DAB Rev.ZModel: STMicr...
Hi!I use STM32MP151 chip. Use Linux OS. Two master clocks(MCLK) clk_x8(for 48000) and clk_x11(for 44100) connected to I2S_CKIN throw switch. GPIO select it. Can I configure SAI driver and device tree for this situation?
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...
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'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...
