Log:
MFp4: When querying the operating condition of SD cards (using the
application specific SEND_OP_COND (CMD55 + ACMD41), go ahead and allow
100 tries. This gives a timeout of a second rather than the ~100ms
the old style produces.
I've had one old 16MB SD card which needs the extra time. I've now
had reports from the field that other cards need this too.
Originally done at BSDcan 2007 while waiting to give my embedding
madness minitalk.
