Problem
I've received the phyBoard-WEGA-AM335x (1405,1) and tried to flash a new BSP. After I flashed my MLO, barebox-image, linuximage and root.ubi and restarted, phyBoard keeps resetting and fails to boot. I've tried various images and get the same result:

Solution
The issue you are seeing is likely the result of using a power supply that is too weak. The boot log demonstrates that the system reboots shortly after decompressing the kernel image, which puts a greater load on the CPU. Please verify that you are using the power supply that came with the kit, or otherwise consult the hardware manual for the appropriate ratings.
The phyBOARD-Wega-AM335x will require either an AC adapter supplying 5 VDC/ min. 3 A (if using the phoenix connector variant which connects directly to the phyBOARD-WEGA) or 12/24V adapter (if using PEB-POW-01 power adapter).
