Hello friends
I build openwrt 18.06.3 for unielec ut7628
But sometimes it doesn't boot during module sysupgrade for no reason
If the same file is easily upgraded to another unielec ut7628 device
How should I solve this problem?
I'd suspect a hardware issue. Have you successfully flashed any FW - so you can run tests?
If not, can the device be TFTP booted or something?
