I am working on a TK1 application that continuously streams data via the SPI bus to and from the K20.
I have noticed that occasionally the K20/TK1 SPI communications get out of sync.
The commit below mentions a K20 FIFO bug, is there more information about what prompts it etc, and how the workaround fixes it?
This commit implements a workaround for the FIFO bug, but I can not find the K20 source code for firmware version 0.9?
