ChibiOS Free Embedded RTOS

Yes, that's what I have been using. But I have been having issue with DMA caching. For some reason occasionally SCB_CleanInvalidateCache() seems to not work, I tried disabling Cache altogether, but somehow that also fails with stack corruption when AXI SRAM is set for Stack memory. I am probably going to write a separate driver for the chip that uses our bounce buffer system (Ardupilot Project).

Hi Giovanni,
I think I found another issue with QSPIv2 Driver, so for receiving data instructions we are ending wait on Transfer Finish interrupt, but the MDMA transfers might not have pulled all the data from FIFO yet. I believe right path for Receive call to finish is in MDMA interrupt. For send I think Transfer Complete is correct location. I have attached the patch for the same.

Hi,

I committed some of the patches but implemented some things differently. Could you assess the current state of the trunk code? I have not a board for testing this right now.

Note, mcuconf.h files have been updated, you should do the same in your project.

Any news?
