Arduino for STM32

I'm working on storing arduino sketch in qspi on a stm32h750b-dk board but so far have not succeeded. Work in progress. But the procedure goes something like this: 1. Create a bootloader in stm32cubeide stored in 750 internal flash. This would configure the qspi, then enable it in memory mapped mode...

I have a stm32h750 discovery board with scram that I would like to make visible to the embedded software. How do I go about modifying the stm32h750 generic variant files to include the scram? And then use in arduino code? I have the board configured in stm32cube, my understanding us that I need to c...

I have a stm32h750 discovery board with both qspi and eMMC flash. How would upload files to either of these to be accessed by the embedded code? Would be great if there was a simple way like esp32fs-plugin for the ide. Also i believe I read thst PROGMEM cannot be placed in the qspi flash as it can b...
