Is stated on STM32MP157 datasheet's boot mode table that the MPU can be booted through UART: – USART2/3/6 and UART4/5/7/8 on default pins Nevertheless, I wasn't able to find which are the default pins for the UART interfaces, on the datasheet or refe...
I have a custom board with a STM32MP157AAB3 and I am trying to boot it with the SD card. I have tested the SD card on a STM32MP157C-DK2 and it boots to Linux fine. When I probe the SD card lines, I can see the clock is toggling for a long time and ...
When booting off SPI NOR I would expect the device (an ST32MP151D) to possibly check the device ID then read a block starting from 0. Where is this fully documented ? What I actually see is two pairs of negative pulses on nCS then it floats open ci...
I'm working on a project using the Seeed Studio STM32MP157C-Odyssey-SoM (it is a module with the STM32MP1, DDR, eMMC and STPMIC). I am making a new PCB into which the module is plugged. When using the module on the original host board from Seeed, b...
What I want to achieve is starting the DFU ROM bootloader (like on a MCU) from a running Linux (maybe via a dedicated kernel module) or, if this helps, via re-configuring u-boot and doing a software reboot cycle.
