5fcdb09791 SAMA5: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift values were reversed resulting in a trashed value for the number of blocks in the BLOCKR register. This was sufficient to prevent DMA writes from working. 2015-03-15 09:35:48 -06:00

2be14d09a2 Fix a bug in the FAT unbind() logic. There were problems with the way certain internal list handling was implemented. The end result is that newly opened or cloned file structures were never being added to the list of open files. So when the unmount() happens, it always looked like there were not open files and a crash could ensue. 2015-03-14 17:33:48 -06:00

8055ba4d03 Pass the umount2() flags to every unbind() implementation. That is where the the decision to umount or not will be made. 2015-03-14 17:22:02 -06:00
Gregory Nutt
f932b26db1 Add umount2(). umount() is now a macro that just calls umount2() with flags = 0. 2015-03-14 16:48:45 -06:00

c5953bd0e9 Debugging and manuals (this one https://www.sdcard.org/downloads/pls/simplified_specs/part1_410.pdf
and this one https://www.sdcard.org/downloads/pls/simplified_specs/part1_410.pdf) shows that ACMD23
must be preceeded with CMD55 command as any other ACMD commands.

Also, after the block reading wait loop must be inserted before writing the next block of data to
the sd card
