Connecting to probe 1 core 0 (using server started externally) reports:

Reconnected to existing LinkServer process.
Server OK but no connection to probe 1 core 0 (after 3 attempts) - Ee(42). Could not connect to core.
Failed on connect: Ee(42). Could not connect to core.
No connection to chip's debug port
The wire and connection is good, the device is even detected in device manager, but somehow this is not working
I already uninstall and install everything
Could someone help me pls?
Hi,
I suppose that you connect the J17 Type C USB connector to PC via USB cable to download and debug. In the case, for all the jumper, you only need to close J22 and J24 two jumper, open all the other jumper.
I attach the picture, pls check if the jumper is correct or not.
If you still have issue after you configure the jumper, pls update the ticket.
Hope it can help you

Hello @xiangjun_rong
Yes, USB Type C is connected to J17 and the only two closed jumpers are J22 and J24, all the other jumpers are opened.
I was able to update the firmware by following the steps mentioned in https://community.nxp.com/t5/MCUXpresso-IDE/FRDM-MCXN947/m-p/1816631
Nevertheless that didn't solve my issue, i still face the error "Unable to open probe index 1" when i try to debug.
I can see that the probe is detected by running this command, but it is not opened yet.
Hi,
This is a trick, but I do not guarantee it can solve your issue, anyway, pls have a try.
On the FRDM-MCXN947 board, holding the ISP SW3 button, then insert the J17 USB connector to power up the board, then release the ISP SW3.
The first step is clicking "Build", the second step is clicking "Debug"
Hope it is helpful.
