- Debian IoT image
Keyboard connected to USB
3G USB dongle connected to USB port
Powered by micro USB port
On checking the system logs, I realised that the device does a clean shutdown (possibly because of PMIC low power trigger), so I have disabled the power button
Assuming it is a power issue, I have now connected a 5VDC, 2A supply to P9 header, but the same issue is observed.
I have checked the documentation but I am unable to figure out what is the minimum supply needed to keep the device operational when more than one USB peripheral is powered by the device.
