DM365 MMC1 error -22 whilst initialising SDIO card

Hi,

Can you try the fix discussed in the link https://e2e.ti.com/support/embedded/int-embedded_software/f/118/p/41061/143086.aspx?

Hi,

it seems a broken link.

Hi,

I am pasting the fix from the link:

Hi,

 I have modified this function,but the error is still, in function dm365_evm_init(),I add two row as below:

    /arch/arm/mach-davinci/board-dm365-evm.c

static __init void dm365_evm_init(void)
{
 evm_init_i2c();
 davinci_serial_init(&uart_config);

 dm365evm_emac_configure();
 dm365evm_usb_configure();

 dm365evm_mmc_configure();                // added by yuwei
 davinci_setup_mmc(0, &dm365evm_mmc_config);  

davinci_setup_mmc(1, &dm365evm_mmc_config);          //yuwei add

.....

I print some register as below,are those data right? why the mmc1 does not work? anyone can help me? thanks a lot!

pinmux0=fd0000

pinmux4=51554515

pupdctl1=fa07f03f

Hi,

I see that MMC/SD1 is muxed with few EMIF pins. Can you disable NAND from menuconfig and see whether that helps?
