This is still RFC because micro SD card does not work with u-boot but it
works in Linux. I do not know how to troubleshoot the issue. Any pointers
would be really helpful.
I forgot to add the error message. Here is the output from USB serial.
=> mmc list
mmc@4744000: 0 (eMMC)
mmc@4784000: 1

Card did not respond to voltage select! : -110
Thanks.
Hi!
Is card detect GPIO set correctly for board?
Maybe you can verfy card detect is working by repeating the command:
gpio status socXX
(where XX is your cd-gpio) while inserting/removing the SD card.
