TDA2HG: Earlyboot:mmc load_firmware failed

Sans
Intellectual 450 points
Part Number: TDA2HG

Hi,

My software version: visionSDK3.08.

I used earlyboot to reduce uboot startup time. 

It works fine on sdcard, but it does not work when download to EMMC.

Boot log:

U-Boot SPL 2019.01 (Aug 28 2020 - 15:12:31 +0800)
DRA752-GP ES2.0
no pinctrl state for default mode
Card did not respond to voltage select!
Firmware loading failed

Trying to boot from MMC2_2
uclass_find_device ret = 0
uclass_get_device_tail ret = 0
spl: mmc boot mode: fs
Loading Environment from MMC... *** Warning - bad CRC, using default environment

Looks like mmc failed to initialize.

Is there any problem with mmc initialization timing?

    Hi,

    Can I know the all steps you followed for the EMMC boot? 

    Thanks

    Hi,

    I started with an SD card, and then used a script to download the targetfs to EMMC.

    It can work normally before using earlyboot.

    I checked the code yesterday and found that mmc1 was specified in dts. I made the following modifications and it works normally.
