Re: Question about omap_hsmmc driver

2010-05-25 Thread Neil Deshpande 
Hi Enric,

I am facing the exact same problem with my board. I am using a Marvell 8686 
SDIO module connected to OMAP3 on MMC2. It works in 2.6.27 but when upgrading 
to 2.6.32 I am seeing CMD5 timing out. Could you please guide me to the 
solution?

Best regards,
Neil

Re: Question about omap_hsmmc driver

2010-01-07 Thread Enric Balletbò i Serra 
Hi,

The mux configuration is set at u-boot level and this works with
kernel 2.6.28 so I suppose the mux configuration is setup correctly.

Looking at driver I see new data in twl4030_hsmmc_info struct. Please,
can you explain a bit the transceiver, ocr_mask and ext_clock  ?

Just for information, on IGEP v2 the MMC2 should be at 1.8V and don't
use twl4030 regulator.

Thanks a lot,

  Enric

RE: Question about omap_hsmmc driver

2010-01-05 Thread Madhusudhan 
Hi Enric,

You see from the log there is a timeout on CMD5. This could happen because
of multiple reasons. One of them is muxing of CMD/CLK lines. Or it could be
due to negotiation of voltage.

I would look at these things first.

Regards,
Madhu

Subject: Question about omap_hsmmc driver

Hi all,

I'm having problems trying to run the SDIO WLAN module on my IGEP v2 board
using the latest omap kernel (2.6.33-rc2). The SDIO WLAN module is connected
to the MMC2 using 4 wires. With an older kernel ( 2.6.28 ) works fine but
the same configuration with 2.6.33-rc2 do not detect the SDIO card.


Any idea to solve the problem ? There is a substantial modification in this
driver. Any help will be appreciated. I attached the log.

Thanks in advance,
