@rtel

I would be grateful if you could keep us informed so we can see if there is anything we can do to upstream the changes.

I have a working solution:

Extending the xPortPendSVHandler save area for ARM_CM0

Thanks so much, Jeff! The version that runs: port.c (24.9 KB)

but, apparently, Raspberry is working on their own port that will have a more efficient solution. See Context switching breaks SPI/DMA - Page 2 - Raspberry Pi Forums
