Yes the example program: Examples / Portenta_SDRAM / SDRAM_operations does run correctly. The one noticable difference between the verbose compiler outputs between my project and the example project is the following warning:
WARNING: library ArduinoGraphics claims to run on samd, renesas_uno architecture(s) and may be incompatible with your current board which runs on mbed_giga architecture(s).
is this an issue? how would I fix it?
Thanks
