ZOOM1 & SDP2430: MMC/SDIO: doesn't work at all

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi,

I have a Zoom1 (3430 LDP) and SDP2430 devices.

I work on SDIO driver.

On both devices I have problems with SDIO using community kernels:

    $ uname -a
    Linux OMAP3430LAB 2.6.27.10-omap1-00207-g26d16da #1 Mon Mar 2 15:50:14 EET 2009 armv7l unknown

To build a kernel I've used omap_ldp_defconfig

On kernel boot I get the following:

Also on SDP2430 I can observe the following:

    There is 2 LEDs (MMC1-1V8 and MMC1-3V0) near the MMC1 slot.  When I use
    an "official TI kernel" for SDP2430 (package version CSSD_Linux_18.12,
    kernel version Linux-2.6.14.7-arm1-omap2) SDIO works well and LED
    MMC1-3V0 is always on when kernel is booted. But with latest community
    kernel both LEDs are off and SDIO doesn't work and there are no logs
    on SDIO card insertion.

Did someone encounter a similar problem with SDIO? Or maybe someone can
advise me to build kernel from some special branch or to use special config
options?


Best regards,

Dmitriy
