Hello all users, this is my first post on this forum.

I'm new to STM microcontrollers and I have bought

XCore407I 

board. I have got STM32L0 DISCOVERY board with debugg connector CN5, whitch can be use to programm/debugg external applications. I tried to connect DISCOVERY CN5 pins to XCORE board and use Attolic True Studio to programm processor on the xcore board but the software can't connect to the target (Error 4). As I read in Discovery board manual to programm external application I have to remove 2 jumpers from the board and connect CN5 pins to my application (XCORE board in this case) according to table 3 (on 15 page) in Discovery manual. I made those steps but software do not see processor on XCore board. Has anybody any suggestions?

The systems must share a common Ground, and the target must be powered.

Hi,

Thank you for your reply. The problem was with supply indeed. I powered my target board from discovery board (not from usb) and it ran.
