AM4379: GP EVM can't detect eMMC in U-boot

Hi Biser.

Thanks for your response.
Could you explain more details if I should make modification on board for detecting mmc 1?

I can detect mmc dev 0 but mmc dev 1 can't be detected.

Thanks.

I think that the software will need to be modified. I'm not an expert, so I have asked the software team to comment. They will respond here.

Hi Kemal.
Thanks for your message.

I checked the thread you sent me.

Now, I got message from u-boot, that is "no mmc at mmc 1 slot".
I have changed emmc 8 bit mode to 4 bit mode for booting emmc.

now my pin mux is like below.
static struct module_pin_mux mmc1_pin_mux[] = {
{OFFSET(gpmc_csn1), (MODE(2) | PULLUDDIS | RXACTIVE | DSPULLUDEN)},
{OFFSET(gpmc_csn2), (MODE(2) | PULLUP_EN | RXACTIVE | DSPULLUDEN)},
{OFFSET(gpmc_ad8), (MODE(1) | PULLUP_EN | RXACTIVE | DSPULLUDEN)}, /* mmc1_dat0 */
{OFFSET(gpmc_ad9), (MODE(1) | PULLUP_EN | RXACTIVE | DSPULLUDEN)}, /* mmc1_dat1 */
{OFFSET(gpmc_ad10), (MODE(1) | PULLUP_EN | RXACTIVE | DSPULLUDEN)}, /* mmc1_dat2 */
{OFFSET(gpmc_ad11), (MODE(1) | PULLUP_EN | RXACTIVE | DSPULLUDEN)}, /* mmc1_dat3 */
{-1},
};

Also I connected the wire with emmc depending on pin mux function.

Kindly help.
Jense.
