Through J1 header

There shouldn't be any problem in powering the device using the arduino header (J1).
But to power the board to 5V, the input power supply must be above or equal to 5V and not less.
In case you need to power the board only to 3.3 V, then connect the System Power Supply Jumper (J9) to 3.3 V and try powering the device again.
Also make sure that the PSoC 4 Power Supply Jumper (J13) is connected.
If this doesn't work, then check you voltage regulator circuit and the ground connections.
