Re: PIC32MX695F512L - USB multiple sector read
I think a different version of MLA will not help much.
MLA for PIC32 was mostly abandoned after v2013-06-15,
and most of it was discarded in versions after that.
MDD File System was then v1.4.4
There are several threads in these fora about using FatFs by Elm-Chan to replace the filesystem code in MLA,
and using DMA for transfer from SD-card.
