I have a problem to get the ethernet to work with the PHY AR8035 (Atheros). The board is from MYiR (MYC-YA157C-V2), but they are only providing yocto based image and I'm doing my work with buildroot. I'm using the bootlin buildroot branch: st/2021.02...
Hello, I'm trying to PWM some pins using the sysfs interface on the openSTLinux but unfortunately, it's not working.I've been changing the device tree files in order to get it working, but still without success.I'm trying to follow this wiki but when...
We are trying to use circular DMA to transfer data from ADC1 into a buffer in MCU SRAM using CubeMX-generated code to configure the ADC and DMA. The DMA stream encounters a transfer error on transferring the first item. I have tried clearing the DMA ...
The RTC clock is on motherboard and usesthis driver (M41T62). I obtained source code from your website. I try to compile this driver as a linux module (debian). I have learnt that this driver is not supported.
Hi, I downloaded the image file required by STM32MP157-EV1 from Yocto, but this error occurred when I used ST32CubeProgrammer. Does anyone know how to solve it?Error:Yocto image information:
I tried setting the i2c frequency to less than 20KHz but I got the following error:[ 1.788573] stm32f7-i2c 40012000.i2c: no solution at all[ 1.792517] stm32f7-i2c 40012000.i2c: failed to compute I2C timings.[ 1.798793] stm32f7-i2c 40012000.i2c:...
Hi,we are working on a sensor data reading application based on your logic analyzer example project. But in our use case the data are sampled on a FPGA connected via QSPI. We have hard realtime requirements (far below 1ms) of reading the data and tra...

Hi, I am using my custom SOM board based on STM32MP157CAC3 chip. The DDR, SDMMC1, UART4, I2C4 & PMIC configuration is same as of stm32mp157c-DK2 board. even I have used the same pin configuration in my hardware. For USB OTG, I have left USB ID and US...
Hi,I am working on a custom board based on STM32MP157F and I am having some issues with USB and EHCI driver in U-Boot as well as with USB and OTG controller in U-Boot and TF-A.Once Linux is booted USB with EHCI driver works fine, but in u-boot it doe...
