AM4376: Issue in SD card detection in custom board

Part Number: AM4376

Tool/software:

I am facing issue while detecting SD card in custom board.

Detection is infrequent.

Most of the time SPL, U-boot, and Kernel image is getting transferred from SD card to NAND using fatload but facing issue for rootfs (approx 60MB).

Checked hardware connections for SD card. Looks OK.

What could cause the issue and how to resolve it?

  • Also face issue while booting from SD card:
    Log:
    CCCCC

    spl: no partition table found

    ### ERROR ### Please RESET the board ###

  • We'll need more details to understanding the issue.
    1/. what is Linux SDK version?
    2/. how many boards under testing?
    3/. Is the issue reproducible consistently or intermittently on one board or multiple boards?
    Best,
