I have another question please. Does the sd8686 require an SDIO I/O reset (CMD52 setting bit 3 of address 0x6 of the CCCR) to it after powering it on ? Daniel (cc'ed) is trying to power it off and back on, and it does seem to work in the first time, without sending a reset. In the second time, though, the card doesn't answer CMD5 anymore, unless Daniel is sending it an SDIO I/O reset. I was wondering whether this is an sd8686 requirement, or whether we have some other issue at hand.
