Same here. I tried it several times, every time openwrt-21.02.3-ath79-nand-glinet_gl-ar750s-nor-squashfs-sysupgrade.bin flashed fine but trying to flash openwrt-21.02.3-ath79-nand-glinet_gl-ar750s-nor-nand-squashfs-sysupgrade.bin the lights stopped flashing a bit too quickly and then I couldn't get ethernet to connect, had to go back to uboot and reflash NOR to get anything working.
When flashing fails, should I expect to be able to recover any error log somehow, or is it more of an "either it works or it doesn't" kind of thing? I hope somebody figures this out eventually. It seems pretty consistent that we're all seeing issues only with NOR-NAND.
If you flash nor nand using the stock firmware advanced settings, does it work? If it doesn't, try what I did
- Go to uboot and flash openwrt-21.02.3-ath79-nand-glinet_gl-ar750s-nor-nand-initramfs-kernel.bin (do note that this version of openwrt only saves changes in ram, changes will be lost after reboot)
- Go to uboot again and this time flash the stock firmware
- After that, go to advanced settings and go to the stock's firmware luci.
- Go to system > backup / flash firmware. Under flash new firmware, press the button "flash image" and flash your nor-nand flash copy glinet_gl-ar750s-nor-nand-squashfs-sysupgrade.bin [NOT KERNEL]
This worked for me, I guess I did it by accident or it was what I was instructed to do by frollic.
