Hi,
I want add support for STM32H747I-DISCO from STMicroelectronics, for the purpose of education. Want to use U-Boot as boot-loader for my projects.
Here you the official website from the board: https://www.st.com/en/evaluation-tools/stm32h747i-disco.html
But there some issues on the website:
- According the website, the board has 256Mbit external SDRAM
That's not true. There is a 512MBit SDRAM from ISSI mounted.
Can I release a patch series here, when my work is done? I don't know if there any interest for other users exists, to add here the support to U-Boot.
Yes please, it's still useful to get a new STM32 board supported in U-Boot ;-)
Currently creating the device-trees for the SoC and the board. But must at least modify (fix) the drivers for the board:
drivers/clk/clk_stm32h7.c has some issues in the probe function:
The endless loop of dead, without a timeout when reading the registers on some possible condition, without warn the user (put some error messages and call the hang function).
Patrick and i saw your mail about this issue, and i agree, in some case there is an issue with this clock driver. Patrick will answer to you about this issue.
Thanks Patrice
Kind regards,
Johannes K.
