Boot loop at Uboot screen

  • So, I had the system up and runningwell, executing a systemd service on boot. The system had an abrupt power cycle unfortunately and then the boot process remained stuck at the uboot for 2-3 loops and then boot up into Linux for 2-3 times, but now it does not boot into Linux at all and stays in a continous boot loop at uboot.


    I used the recovery tool to renew the uboot and nboot, but even that does not go through completely because the system reboots in the middle and breaks the process. Kindly let me know what has gone wrong and a possible solution.

  • Hi,


    Thanks for the suggestion, and after having spent an entire day on it, it turned out to be a hardware issue, but a faulty power supply was the case. It was just bad enough to cause problems but good enough that it seemed to be working fine with proper power output.


    best regards
