Hi all,

I have some Leftover generic STM32H743 boards from another project.
They have 32MB of SDRAM. Is there any chance it could run the CMMs basic?
VGA etc. not needed, just using the usart1 serial port would be enough to start with.

This won't work for you?

It's a supported CPU, so that's a good start.

Compare the SDRAM address and peripherals with those on the supported boards - if they're the same it should work.

If not, can you rebuild the code?  If not, that's probably an end to it.

BTW you can easily program your board with the current firmware in case you want to see what happens.  You can't "brick" these chips by loading wrong code.

Thanks guys, I was totally unaware of the armmite version of mmbasic. I’ll start testing  asap.
Although I’m guessing no ltdc(vga) or fmc(sdram) in the armmite version.
Still, lots to try out!
Cheers!
