Subject: the at91 mmc controller does not recognized my sdio wifi chip after a reset.
Date: Sun, 21 Mar 2010 10:56:54 +0100 [thread overview]
Message-ID: <cdd918981003210256p6843c5a6i34dd48c4d198c8ed@mail.gmail.com> (raw)
Hello,
I'm writting to the both mmc & libertas mailing list because i might
think the problem is related.
I'm using a prototype board running a AT91sam9g20 processor. I have a
libertas sdio wifi chip connected to my MCI controller.
I've applied the 2.6.32 bsp patch.
When I power up the board (power on reset), the sdio chip is well
probed by the mci controller.
But when i reset the board, the mmc_rescan function failed because the call to
/*
* First we search for SDIO...
*/
err = mmc_send_io_op_cond(host, 0, &ocr);
return 110;
so my sdio chip is not recognized by my kernel.
I've tried to apply that patch "sdio : recognize io card without
powercycle" (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=516a82422209e078345d0ca54b16793d7bfd4782
) without success.
Here is a dump of the mmc dialogue when the board is only reseted :
