s3c6410 linux 2.6.27 firmware load error

[林旻億]

My target is s3c6410 and I am using the linux 2.6.27 kernel and the
associated libertas driver.

And my sd8686 chip is build on the board.

When I start the libertas driver, I got the following message

mmc0: starting CMD52 arg 10004000 flags 00000195

mmc0: req done (CMD52): 0: 0000100d 00000000 00000000 00000000

SDIO: Failed to disable device mmc0:0001:1

libertas_sdio: probe of mmc0:0001:1 failed with error -110

 

I trace the if_sdio.c , then I found the driver break on 

static int if_sdio_prog_real(struct if_sdio_card *card)

{

        ……

        

                req_size = sdio_readb(card->func, IF_SDIO_RD_BASE, &ret); =>
ret always return -110

                if (ret){

                        goto release;

                }

                        

 

                req_size |= sdio_readb(card->func, IF_SDIO_RD_BASE + 1,
&ret) << 8;

                if (ret){

                        goto release;

                }

        …….

}

 

Can tell me how to fix this issue ?

 

Thanks
