LPC54S608J512 and MCUXpresso 10.1.0 589 - Debug wont launch "Awaiting telnet connection to port 3330 ..."

I have been working with LPC54S608J512 and MCUXpresso 10.1.0 589, for several months.  Suddenly I can't get a debug session to launch it gets stuck at "Awaiting telnet connection to port 3330 ...".   I have tried the following.

  • Created a new debug session - still get "Awaiting telnet connection to port 3330 ..."
  • Got a colleague to run up a debug session on my Target Hardware and Link2 - this worked fine so PCB, Link2 and cables all good.
  • Used my Link2 and LPCXpresso(V7.7.2) on my PC to run a debug session on a LPC43S20 based target. This also worked fine.
  • I have switched AV software off and firewall off - still get "Awaiting telnet connection to port 3330 ..."
  • Reinstalled MCUXpresso.

Anyone got any ideas?

Full console output below.

Thanks

Derek

Made a bit of progress - seems to be something to do with Antivirus and/or Firewall.  I thought I'd ruled this out previously as switching it off didn't seem to help.  Trying again, having AV and firewall off got it working.  However switching the firewall and AV back on and it still seems to be working - so not sure what's going on.  Will report back if I get any more answers.

Hi Derek Robertson,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Maybe you can try these two tricks recover debug function
1. Clean the project
2. Delete the project, then reimport the project.
3. Update the LPC-link2 with the J-link firmware, then debug the LPC54S608J512 again.
Have a great day,
TIC

This problem has came back.

1. Clean the project - This didn't help
2. Delete the project, then reimport the project -  This didn't help
3. Update the LPC-link2 with the J-link firmware, then debug the LPC54S608J512 again.  Is there a document to describe the process?

When I get stuck here, I can see that crt_emu_cm_redlink.exe  is sitting listening on port 3330. What Process should be connecting to this port?  as I am suspicious that my AV or firewall is killing this process.

I've reverted back to my original IDE 10.1.0 as 10.3.1 is causing me other issues

Still not entirely certain why this was was intermittent but I seem to have this resolved.

redlinkserv was being blocked by my firewall, think a windows update changed my settings!  I have now allowed this to run (on port 3025).  Once I allowed it, I was initially getting the same issue, restarting MCUXPresso did not resolve it but, restarting and hitting the "red boot" icon and then "LinkServer" seemed to do the trick.

Fingers Crossed :smileyhappy:
