Re: Unable to flash custom image

I apologize but the problem still persists. In fact I am only able to flash images when I am using a specific docking station from DELL.

I have two Edison Arduino Breakout Boards (the big ones). Successive is what I have tried so far:

1. Laptop A USB power supply (no flashing possible for both boards)
2. Laptop B USB power supply (no flashing possible for both boards)
3. Desktop PC USB power supply (no flashing possible for both boards)

So I tried to use a laboratory power supply. According to Section 3 in edison-arduino_HG_331191-002.pdf I applied 15V with a maximum of 1.5A to J1.

Result: The edison booted while using approx. 100-200mA but flashing was also not possible for both boards.

So I tried to use the USB-Port of my DELL PW380 docking station. When using this docking station the flashing process is reproducible for both boards.

Now I am very unsure If I am doing sth. wrong or if the edison flash process is only possible if very specific voltage and current limits are kept?
