Hi,
I'm trying to debug a project created on MCUXpresso that I've ported on the FRDM-KE15Z. I want to use the JLINK Ultra+ debugger and created a debug configuration for it but the probe cannot connect at all. I've tried with one of the project examples, (to rule out any particulars with my own project) given in the SDK but get same results so I'm assuming there's something else going on.
The version of the FRDM-KE15Z board (29023 REV B3) I received did not have the SWD connector (J17 from the schematic) so I've installed one and also made sure to remove J7 and J8. The board is powered by the USB cable. I wanted to use an external 5V supply but it seems the board version I have does not have D8 populated and I was not too sure what else to do to make the board working with an external supply without damaging it.
So first, what are the steps to make MCUXpresso debugger to connect with the FDRM-KE15 board using an external JLINK debugger? Is there a special DAP FW that needs to be installed or jumper config to be set?
Second, If I want to power the board with an external supply, is there anything else we have to do than soldering a wire to pin C of D8 and remove the USB cable ?
Thanks,
LM
Hello,
I reviewed the schematic and I suggest this recommendation could help you.
Tell me if you need more information.
