Avtar Singh Posted August 28, 2019 Author Posted August 28, 2019 please someone provide the solution to this problem
qstaq Posted August 28, 2019 Posted August 28, 2019 Watchdog is part of the kernel and will not help you in this situation if, as you say, the device is hanging BEFORE the start of kernel loading You need to provide the serial debug output from the u-boot phase of the boot process AND the output of armbianmonitor -u if you want some help, your question doesnt really provide any technical info that can be used to troubleshoot
