I am trying to get an Open-Q 820 uSOM dev kit running. The problem is that the SoC reboots after about 15s (it varies from 12s to 18-20s). Tried with the official built images from the BSP, tested with Android M 2.2 and Android N 3.2 BSPs.
I also got the Android N 3.2 booting with the Linaro 4.14 kernel - but it also hangs after about 15s, however it does not reboot just freezes (probably because there is no Watchdog driver?).
Fastboot mode works fine.
Recovery mode works as well, no reboots or hangs.
