Hi,
I am currently working on writing a SDIO Wi-fi device driver on WinE
5.0. When I send CMD53 to the card I always get a Write CRC error.
What might be the issue? There are a lot of CMD52 before this CMD53
which run successfully but once CMD53 is sent to the card I get an
error.
One more thing, when I send CMD53 how will the data be written to the
SDIO card? How does the Bus Driver send us the data to be written in
this case?
Also the specs say that the data from the Dat[x] lines will be written
to the card in this case. But who will put the data on the DAT[x] lines
for the card? Also the spec says that the data from the DAT[x] lines
will be written to the card. Who will put this data on the DAT[x] lines
for the card in this case?
Regards,
Varun
