Hi All,
I working on a T1042 based custom board that has an on-board eMMC (8GB, GLS85VM1008A-M-I-LFWE-ND202). I have successfully booted uboot 2019.07 on my board.
I'm facing an issue with mmc command set, when I issue an 'mmc list' command once the board boots up it lists " FSL_SDHC: 0 " and 'mmc info' lists the details of my eMMC.
Once I issue 'mmc dev 0 0' command, then nothing is printed on my console. After this when I issue 'mmc info' it also prints nothing on the console. But 'mmc list' still lists the " FSL_SDHC: 0 ".
Why is it so? Am I doing something wrong?
Please the below u-boot log for detail.
Regards, Amarnath MB
