Card did not respond to voltage select! : -110 => mmc dev 1 switch to partitions #0, OK mmc1 is current device4 4) The same in Linux if we check mmcblk, there only mmcblk1. # ls /dev/mmcblk* /dev/mmcblk1 /dev/mmcblk1p1...
Currently we can boot from an SD cardand met an issue that mmc0(emmc) cannot be detect on custom evm board in uboot and linux. And we always got "Card did not respond to voltage select". We try to use ""mmc rescan" in uboot, but still the same. ...
After inserting a card on boot-up (or removing and inserting a different card) you first need to use mmc rescan to cause the system to check if there is a card present currently and do some other backend work. Share Follow answered Aug 3, 2016 at 11:45 Tom Rini 2,1639...
