 Hi,

I have am3517 based board and Libertas sdio (4 wires)
wifi connected directly (no transceiver / level shifter) on mmc2
(which is named mmc1 in s/w).

am3517 is configured (h/w) for 3.3V and so is Libertas wifi.

dmesg | grep mmc1 shows:

-------------------cut---------------------

Libertas is powered up and gets reseted properly.
On the oscilloscope, I see some communication going
on the CMD line and stops after some time.

am3517 PSP from TI, does not even registers/enables
the wifi combo found on am3517evm.

Have anybody got the mmc2 working on am3517?
May be with transceiver?

Any help will be appreciated.

Thanks

Make sure the MMC2_CLK pin is muxed as an input so the clock can
feedback to the module. Also, you may need to set
CONTROL_DEVCONF1.MMCSDIO2ADPCLKISEL=1 if that exists on the Sitara. I
had the same problem on the OMAP3x.

Also, shouldn't you setting the mux values for sdmmc2_* not sdmmc1_*
if your chip is on MMC2?

Well, this is left unintentionally, I think I can remove this.
omap2_mmc_mux() in arch/arm/mach-omap2/devices.c
does the proper muxing of the lines according to .wires field
of the platform data. I think, I don't need to do any muxing
for the mmc (4 wires) at all in the board file. Am I right?

omap2_mmc_mux() in arch/arm/mach-omap2/devices.c is handling this
and I think properly or else any omap will fail using the mmc2.

I will try that.

Nope... this does not help.
Also, Stanley has restricted the above setting to non-am3517 cpus
in commit 03e7e170d6fdc5b6f75d1ab2cc1a6cb4f2b6b8c4

Any other suggestions?

Stanley, can you help us with this?

I've got this exact same problem on a OMAP35x based board. We have
MMC1 connected to a SD card cage and MMC2 connected to an eMMC. I can
detect an inserted SD card and eMMC during boot up, but if I suspend
and resume the device, I get a ton of timeout errors on MMC1 (the SD
slot) and the RFS that's being used from it ends up having lots of
EXT3 journal errors and ends up hosing itself..

I've confirmed that the CONTROL_DEVCONF1.MMCSDIO2ADPCLKISEL is set to
1 as well and that doesn't affect any change.

I was using a 2.6.29 Kernel on this board before and it had no
problems, I then jumped to 2.6.32 and this problem appeared. I'm now
running the latest linux-next (2.6.35) Kernel and it also presents the
problem..

Any guidance would be appreciated..

Ashwin,

I'm not sure your problem is the same as the one originally posted.
Do you have CONFIG_MMC_UNSAFE_RESUME enabled?

Anand,

Yup, have MMC_UNSAFE_RESUME set. I'm actually using the
"omap3_defconfig" to build my Kernel..

CONFIG_MMC=y
CONFIG_MMC_DEBUG=y
CONFIG_MMC_UNSAFE_RESUME=y
# MMC/SD/SDIO Card Drivers
CONFIG_MMC_BLOCK=y
CONFIG_MMC_BLOCK_BOUNCE=y
# CONFIG_MMC_TEST is not set
# MMC/SD/SDIO Host Controller Drivers
# CONFIG_MMC_SDHCI is not set
CONFIG_MMC_OMAP=y
CONFIG_MMC_OMAP_HS=y
# CONFIG_MMC_SPI is not set

The interesting thing is that enabling MMC2 causes me issues on MMC1
though I'm not doing anything on MMC2's eMMC apart from discovering
it..

Thanks
