Hello,I am running a Linux image based on meta-st-stm32mp (hardknott branch).I currently have the following in my host device tree:reserved-memory { #address-cells = <1>; #size-cells = <1>; ranges; ...

Hello!I've got a problem configuring USB OTG on a board based on the STM32MP157C. This is actually the Odyssey board by Seeed Studio, which is not directly supported by STLinux as far as I know. Actually we have custom hardware with the STM32MP157C S...

@ArnaudP I didn't know that SRAM4 is accessible from the M4 if you don't use DMA buffers on Linux, as it's not shown in the RAM mapping. Good to know! I see that you don't use retram for code, but only mcusramcode at 0x10000000. I guess you could go...

@ienecodeNo. I worked around it by writing a systemd service that uses gpioset on startup.

In principle, I think I got it to link properly. But I still get crashes once I actually try to call a function that's output by the linker into the mcusram section. I can confirm (objdump -d) that the code is emitted correctly and it's supposed to b...

I see. I was somehow hoping that the 64kb RETRAM size is arbitrary and can be extended.So to effectively get more than 64kb of code into the image, you would have to move code into the MCUSRAMx sections without copying, ie. the ELF loader will have t...

Hello @ArnaudP,I have read this article. From what I understand, it should be possible to just enlarge the retram reserved-memory section, where the M4 firmware is initially loaded into. However, rproc_elf_load_segments() is still crashing in the A7 ...
