Whow, some activity on the mailing list other than from me
yes, H7 is on my radar. In some branch, I had the app/uart running with
However there are several problems:
- Device availability:
Only the expensive Eval boards are available.
I have 2 Nucleo boards, but the first one had problems with flash
programming right from the start. I fear the second one also developped
those problems too, but have not investigated further.
- Debugger/Flasher availability:
Neither OpenOCD nor blackmagic supports the chip. I did some work for BMP
https://github.com/UweBonnes/blackmagic/tree/h7, but this needs more love
and testing. Perhaps the problems with the boards above are caused by the
debugger tests ?
- New devices
The H7 differs in clock setup, DMA, SPI, Ethernet and more.
There is a lot of work to do...
