I appear to have sysupgrade.bin with a micosd card inside .
this is the result from booting with it currently
root@OpenWrt:~# block info
/dev/mtdblock0: UUID=“14715xxxxx” VERSION=“1” TYPE=“ubi”
/dev/mtdblock6: UUID=“xxxxxxxxx-1a8d9629-07b5039a-40681daa” VERSION=“4.0” MOUNT=“/rom” TYPE=“squashfs”
/dev/mtdblock7: MOUNT=“/overlay” TYPE=“jffs2”
/dev/sda1: UUID=“xxxxxxxx-ffbf-4abb-a0ce-291250cd4d78” LABEL=“overlay” VERSION=“1.0” TYPE=“ext4”
/dev/sda2: UUID=“xxxxxxxx-1e3b-47ad-9aea-8c770d08180b” LABEL=“storage” VERSION=“1.0” TYPE=“ext4”
/dev/sda3: UUID=“xxxxxxxx-1694-4d3a-af5b-31081962fb73” VERSION=“1” TYPE=“swap”
here it is booted up without sdcard
root@OpenWrt:~# block info
/dev/mtdblock0: UUID=“1471xxxxxx” VERSION=“1” TYPE=“ubi”
/dev/mtdblock6: UUID=“00794cfc-1a8d9629-07b5039a-xxxxxxx” VERSION=“4.0” MOUNT=“/rom” TYPE=“squashfs”
/dev/mtdblock7: MOUNT=“/overlay” TYPE=“jffs2”
uboot working fine now card is removed.
flashed image openwrt-ar750s-3.201-0402.img from uboot and up again.
don’t recall ever having issues upgrading with system not mounted with extroot but /mnt/sda1/upper from old setup was there and caused issue?
so should I install
openwrt-21.02.0-rc2-ath79-nand-glinet_gl-ar750s-nor-squashfs-sysupgrade.bin nor (not the nor/nand file)
or
openwrt-21.02.0-rc2-ath79-nand-glinet_gl-ar750s-nor-nand-squashfs-sysupgrade.bin nor/nand file
