How can I set up or reset my SD card for the STM32MP157A-DK1 board?

MDann.1 · ‎2021-02-19

Hello everybody,

i have a problem booting the SD card. The problem occurred after I copied the device tree (.dtb) from my project from STM32CubeMx to the STM32MP157A under / boot. When booting, the U-Boot and the start kernel run endlessly. How can I solve the problem?

Thanks a lot

Here is the output from the board:

Hello,

I suggest to use the wiki https://wiki.st.com/stm32mpu/wiki/Main_Page

The Getting started for DK2 will help you to reflash your board https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2

(The tutorial is for DK2, but very same for dk1, except you need to select the dk1 flashlayout)

Note that SD-Card could also be populated directly on Unix (e.g. with an USB => SD-Card adapter)

https://wiki.st.com/stm32mpu/wiki/How_to_populate_the_SD_card_with_dd_command
