I have two devices running KSZAQ excellent firmware. I like to keep them up to date so do regular updates by putting the firmware and device tree in the update folder and rebooting. I have done this dozens of times with no issues.
Anyway one of my boxes updated fine but the second simply won't reboot after the update.
The device has two USB and one microSD slots. I have tried several USB devices plus microSD card using Rufus to create a bootable device in both USB slots but none will boot. The device does not have a reset button so I can't run toothpick.
Anyone any ideas please.
