Apparently it is not possible to set a custom baud rates for UARTs on the STM32MP1.ioctl TIOCSSERIAL fails. With a USB UART dongle that supports custom baud rates this works. Is there a something that can be changed in the device tree or config to en...
Hello,I am currently initializing my STM32MP157CAC3 (TFBGA361) with CubeMX.The processor's datasheet lists USB_OTG_FS functionality as additional functions on PA11 / PA12 but there is no such selection inside CubeMX. In general, there is no USB_OTG_...
Hi,we were facing trouble booting the Ecosystem 2.0 with the new U-Boot (v2020.01-stm32mp-r1). We are using buildroot as the tool to build our distribution. With the Ecosystem 1.2 we could build everything perfectly and the booting was fine too. We u...
Hardware: STM32MP157C-DK2, VL6180 breakout from SparkfunSoftware: CubeMX IDE (1.3.0), buildroot (following the guide from Bootlin here)I'm trying to use the M4 core to communicate with an I2C sensor. I successfully talked with the sensor on the Linux...
Hi,we are currently evaluate the STM32MP for a project and we want to ensure that we can handle all errataissues that concern our usage scenario.In Errata are the points: 2.6.1 to 2.6.4 that discribe DMAMUX issues. At this point my question is:Does L...
Hello guys.I am proceeding in the manner provided on the WIKI page(https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package).However, the following problems still occur in Step 6.[error codes]-----------------------------------------------...

Hi, I have an STM32MP157C-DK2 reference board and it is booting with yocto linux.From the bootlog I came to know that reset reason is checked in the Primary Bootloader by reading a register from the file tf-a-stm32mp/plat/st/stm32mp1/bl2_plat_setup.c...
