Yes, but also that the host will cache blocks in the ums case, so having the cache enabled will only slow things down slightly by lots of memcpy's to cached blocks that won't be helpful.
I think I was a bit flippant by including dfu in this statement, since I haven't used it to access anything except SPI-NOR.
Eventually it seems better to keep the cache enabled for at least DFU to a filesystem (rather than raw block device) since presumably parsing the directory structure to write to a file for DFU would benefit from the cache just like anything else.
I'm not in a position to comment about dfu.
For the record, I think this discussion is good and important, but not a blocker for getting the initial functionality in.
I wholeheartedly agree.
I'm learning a lot and the code's better because of Stephen's feedback.
Regards,
Eric
