Can we swap SDMMC pins in our design ?
Does ST-Linux run for any configuration of eMMC pins, i.e. if it is connected to SDMMC1/SDMMC2/SDMMC3 . or do we need to fix as per reference design / Dev kits.

OpenGL context for drawing w/shaders
I’m new to the stm32mp1, I’m struggling to figure out how to get SDL2 working with OpenGL on the platform. I can create a window with SDL, but if I try to create an opengl window, I get a runtime error that GTX is not supported.I should note that my ...
Which is best optimized for speed, using 4 separate variables or a 4 dimension Array?
I want to ensure I've used the most optimized code. I'm using gcc on linux. I have 4 values to store. If I use an array, I can for() loop as a convenience and shorter code, but is there added overhead compared to just using separate variables and hav...
Pinmux RSVD in mainline Linux
Hi!I use buildroot - NOT openstlinux.My M4 code works fine in engineering mode, but fails in production mode.I suspect that it is due to the device tree file.The DTS file generated by STM32CubeIDE has some pinmux assignments to "RSVD", which fails in...
