I am enabling SPI1 controller and selecting PLL3Q as its kernel clock source on CubeMX. But automatic code is not generated for it.It looks like #DEFINES for SPI1 do not exist in stm32mp1-clksrc.h, while they do exist for other SPI controllers.
Hi All.I want to use the battery to power the RETRAM so that the contents of the RETRAM can be preserved even if the board is not powered.To do this, I connected the battery to the VBAT pin and set the "PWR_CR2_RREN" value to the "PWR_CR2" register o...
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...
