No boot after reboot

Thanks so much for this script. It works awesome with the addition from the #2 issue. After the flashing, everything is fine, I see the ttyACM0 connect to it with screen, everything is peachy.

The issue happens when I reboot it. I do systemctl halt, disconnect the chip, and when I reconnect it to the PC, there's no ttyACM0 anymore. No ssh connection although it was set before the reboot. And in dmesg I only see : usb 1-2: new full-speed USB device number 20 using xhci_hcd

Any ideas what can be wrong ?

I had the same problem and I guess it was because the uboot didn't flush into nand. The chip is always in fastboot mode after restart. @JosefZIla
