Compute CRC-32 checksum in HW with DMA #245

Closed danielschloms closed 4 months ago

danielschloms commented 5 months ago

Description

Both regular hardware CRC, and CRC with DMA are implemented here. For the DMA version, DMA 2 stream 1 is proposed, as only DMA 2 is capable of memory-to-memory transfer as required in the CRC with DMA manual. DmaCrc32() also contains provisional code to convert a byte array into a word array.

Fixes #177

I ran the HW tests on the FlatSat and everything worked, so we can finally merge this PR.
