Many bugs Harmony V3 SST26 (SQI) and MPFS file system
Bug 1: Upload does not complete:
I am finding that the MPFS Upload stalls because after the first call to SYS_FS_MEDIA_MANAGER_SectorWrite() subsequent calls to SYS_FS_MEDIA_MANAGER_CommandStatusGet() never return with SYS_FS_MEDIA_COMMAND_COMPLETED.
They always return 0xFFFF
I believe this is because the means of the DMA notifying completion "up the stack" may be broken.
I notice that the Harmony Configuration tool has set the following:
.isMemDevInterruptEnabled = false,
which would seem to me to be wrong, as whilst the memory chip itself does not have an interrupt line, the DMA driving it *can* interrupt to say "done it, boss".
Does anybody know whether I should alter this setting?
The symptoms may look slightly similar to another post with a similar title, but Luciano's post appears to derive from problems with cache issues - I don't think that's the case for this particular problem - although I guess I may run into that later.
