I've just installed MCUXpresso IDE v11.0.0 [Build 2516] [2019-06-05] onto Win 8.1, loaded all the SDK examples, plugged in a 11u68 Xpresso v2 dev board, built the demos_switch_blinky project, then go to debug the project and the IDE cannot find the debugger probe.
When I first plug the board in it shows as such in the device manager
When I hit the debug button the IDE goes into search mode and indeed seems to find the board because the LED next to the debug chip starts flashing and the device manager changes to this
However after a few seconds I get
And the
"No compatible probes available. They may be disabled, disconnected, not powered, already in use or not compatible with this target."
error in the "Probes discovered" dialogue.
And no amount of cycling the power, rebooting the PC, or restarting the IDE makes any difference.
Thanks for the reply Alice. However before I noticed it I came across this document
https://www.nxp.com/docs/en/user-guide/MCUXpresso_IDE_User_Guide.pdf
and it seemed to have something worth trying, on starting on page 240.
Sure enough my LPC-LinkII UCOM driver was version 1.0.0.0, I followed the instructions and installed v2.0.0.0 and lo and behold it worked.
So, in a nutshell my problem was an old driver, why I don't know as I had just installed the latest MCUXpresso, but I already had an earlier version installed and even a version of LPCXpresso, so maybe the latest install saw that a driver was installed and didn't bother overwriting it. I dunno.
Anyway, thanks for your response, that and this post will sit here now and hopefully help the next person with a similar problem.
Hi Rob,
OK, thanks for your sharing.

Hello Rob Gray,
Please try the below steps:
- Use a jumper connect Link DFU(JP3);
- Connect J5 on board with PC;
- Open MCUXpresso IDE with a new workspace;
- Import a simple demo, build.
- Click "Boot Debug Probe" on menu:
it should shows below:
- Then click "Debug" button to try again:
If still can't work, you can change the debugger firmware to J-link using LPCscrypt:
Hope it helps,
Have a great day,
TIC
