Tool/software: Linux

Hi all,

I used "ti-processor-sdk-linux-am57xx-evm-04.00.00.04/bin/create-sdcard.sh" to create my own SD card and got stucked as below :

mmc1: new DDR MMC card at address 0001
[ 3.554327] mmcblk1: mmc1:0001 S10004 3.56 GiB

[ 3.702218] Waiting for root device PARTUUID=8fe29470-02..

I copied all rootfs (same dtb and zImage) and boot (same MLO and u-boot.img) directories from the EVM SD card and the result does not change. What may be the reason for this problem?

Regards

Ferhat

    Hello Ferhat,

    Seems you are using low class SD card. Can you try to boot with class 10 SD card?

    Best regards,
    Kemal
