Title: Enable SD_mmc2 on Olinuxino A20
Post by: mauricio on May 25, 2021, 06:08:18 PM

Hello

Using Debian Buster on an A20 olinuxino-micro Rev.E, no desktop olimex image

Using command line, I can't get access to SD/MMC2 card

sudo lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 14,4G 0 disk
└─mmcblk0p1 179:1 0 14,4G 0 part /

Where mmcblk0 is micro sd card

I've done also

sudo ls -lah /dev/mmc*
brw-rw---- 1 root disk 179, 0 may 25 10:46 /dev/mmcblk0
brw-rw---- 1 root disk 179, 1 may 25 10:46 /dev/mmcblk0p1

And looked up for a reference to SD MMC2 on /boot/config-5.6.14-olimex, no luck

This has been also asked on this old post , sadly with no response

Is SD/MMC2 disabled ?

Please any hint is appreciated

Thanks

It seems so, I've notified the developers to look into it.
