AM572X: eMMC and SD card device allocation

Other Parts Discussed in Thread: AM5728

I am trying to solve the issue raised at e2e.ti.com/support/arm/sitara_arm/f/791/t/297550#pi316653filter=all&pi316653scroll=false but for the AM5728.

I have an AM5728 board and the eMMC device appears either as mmcblk0 or mmcblk1 depending on SD card detection during kernel's boot time.

How can I make the eMMC to always appear as mmcblk0 please?

Regards

    Can you describe your problem? The post you refer is 3 years old and for a kernel that is no longer supported.

    Hi Biser,
    I have a custom board which is designed based on beaglebone-x15 and I’m using BSP: ti-processor-sdk-linux-am57xx-evm-02.00.01.07-es2.0. Could you please give me some advice with below problem?

    I config 2 files on uboot to boot on eMMC:
    am57xx_evm.h:
    from #define FAT_ENV_DEVICE_AND_PART "0:1"
    to: #define FAT_ENV_DEVICE_AND_PART "1:1"
    and file ti_armv7_common.h:
    from "finduuid=part uuid mmc 0:2 uuid\0"
    to: "finduuid=part uuid mmc 1:2 uuid\0"
    I boot board from eMMC OK.
    Now I want to use Sdcard like extern memory (FAT32, EXT4 or NTFS) and my board boot on eMMC . But when I plug sd card, board can not boot. If I don’t plug sdcard, board boot ok on eMMC. Please help me this problem!

    I look forward to hearing from you.
    Thanks and best regards,
