Exroot config issues

Technical Support
#1

Hi,

I’ve just recently purhcased a GLInet GL-MT1300 and I wanted to update AdGuard but the internal storage isn’t big enough so I’ve added in a SanDisc High Endurance 32GB. When I attempt to perform the Exroot config I run into issues with the sd card its self.

The Sd card it’s self doesn’t show as /SDA/ or /SDA1/ as the guide shows instead I get with block info

/dev/mtdblock5: UUID="f28f0cac-34e0f290-926ce6bd-8164daa0" VERSION="4.0" MOUNT="/rom" TYPE="squashfs"
/dev/mtdblock6: MOUNT="/overlay" TYPE="jffs2"
/dev/mmcblk0p1: UUID="62F9-1705" LABEL="UNTITLED" VERSION="FAT32" TYPE="vfat"

Any solutions to fixing this would be greatly appreciated

I think SD must be formatted as EXT4 to work as /overlay.
Also last firmware recommended.

Just worked on this (for a few hours over several days using GL.iNet and CLI!!) and found the way to reliably access the SD card was to use the procedure here, but on a clean firmware install. Yes, partition for overlay needs to be formatted to ext4
