AM4379: Cann't mount SD card missing dev/mmcblk

Part Number: AM4379
Other Parts Discussed in Thread: TPS65218, AM4372, TLV320AIC3106

Hi,

We have a customed Am437x-gp-evm board installed ti-sdk-rt-am437x-evm-05.03.00.07, The board is work well but cann't mount SD card.

I can write it in U-boot as following, But  when system boot up from NAND, there is no /dev/mmcblk0,mmblk1,...

U-Boot 2018.01-00569-gccad41e-dirty (Jun 08 2019 - 13:39:56 +0800)

CPU : AM437X-GP rev 1.2
Model: TI AM437x GP EVM
DRAM: 1 GiB
PMIC: TPS65218
NAND: 512 MiB
MMC: OMAP SD/MMC: 0
*** Warning - bad CRC, using default environment

Net: <ethaddr> not set. Validating first E-fuse MAC
Could not get PHY for cpsw: addr 0
cpsw, usb_ether
Hit any key to stop autoboot: 0
=> printenv partitions
partitions=uuid_disk=${uuid_gpt_disk};name=rootfs,start=2MiB,size=-,uuid=${uuid_gpt_rootfs}
=> mmc list
OMAP SD/MMC: 0
=> gpt write mmc 0 ${partitions}
Writing GPT: success!

Please advise how to solve this. Thanks!

We check the following :

1) in the modified am437x-gp-evm.dts file:

mmc1_pins: pinmux_mmc1_pins {
pinctrl-single,pins = <

            AM4372_IOPAD(0x900,PIN_INPUT_PULLUP | MUX_MODE0) /* D1:mmc0_clk.mmc0_clk */
            AM4372_IOPAD(0x904,PIN_INPUT_PULLUP | MUX_MODE0) /* D2:mmc0_cmd.mmc0_cmd */
            AM4372_IOPAD(0x8fc,PIN_INPUT_PULLUP | MUX_MODE0) /* C1:mmc0_dat0.mmc0_dat0 */
            AM4372_IOPAD(0x8f8,PIN_INPUT_PULLUP | MUX_MODE0) /* C2:mmc0_dat1.mmc0_dat1 */
            AM4372_IOPAD(0x8f4,PIN_INPUT_PULLUP | MUX_MODE0) /* B2:mmc0_dat2.mmc0_dat2 */
            AM4372_IOPAD(0x8f0,PIN_INPUT_PULLUP | MUX_MODE0) /* B1:mmc0_dat3.mmc0_dat3 */
           AM4372_IOPAD(0x960, PIN_INPUT | MUX_MODE7) /* spi0_cs1.gpio0_6 */
>;
};

&mmc1 {
status = "okay";
vmmc-supply = <&evm_v3_3d>;
bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&mmc1_pins>;
cd-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;
};

2) In the kernnel config:

        <*>   MMC block device driver

        <*>TI OMAP Multimedia Card Interface support

3) the bootup log is( dmesg -k):

I find there are many:  

    omap_hsmmc 48060000.mmc: GPIO lookup for consumer cd
    omap_hsmmc 48060000.mmc: using device tree for GPIO lookup
    omap_hsmmc 48060000.mmc: lookup for GPIO cd failed

Is this the case? but I define the MMC1 in the device tree file(am437x-gp-evm.dts) as shown before.

Best Regards,
