so I was using the vanilla openwrt imagebuilder for 220.127.116.11 for my ar750s worked fine but wanted to try 20.0.2rc2. flashed openwrt-21.02.0-rc2-ath79-nand-glinet_gl-ar750s-nor-squashfs-sysupgrade.bin nor (not nor/nand) from luci without keep settings and cant login from luci. figured I would just have to flash via uboot but uboot screen shows error with redirect to git hub for issues. git hub redirect did not show ar750s was supported. what next?
update: did reset button factory reset and was able to ssh into dropbear. changed password but still no luci login working.
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)
openwrt-21.02.0-rc2-ath79-nand-glinet_gl-ar750s-nor-nand-squashfs-sysupgrade.bin nor/nand file
i remembered I had to flash vanilla first to get parttions aligned with vanilla openwrt so did a
uboot flash of gl-ar750s-3.0-1011_clean.img.
this casues same problem of having luci blank unset password login failure.
