Hi Manual,
Please take a screen capture of the PEmicro Startup tab under debug configuration with your telnet settings in place. In order to get to it, you can click Debug under Debug your project tab which will automatically create a debug configuration. Once it is created, please go to Debug Configurations -> select GDB PEMicro Interface Debug configuration -> go to Startup tab and make sure that Enable semihosting/Console routed to Telnet/Enable Telnet console are checked and Telnet Port is assigned to an available port number.
Please run sudo netstat -nlp in a terminal window to confirm that the default Telnet port is not used by a different program on your PC, otherwise you can always change it to a different number.
When you look for the printf outputs, are you specifically looking in the PE Debug Semihosting Console?
Which device are you currently working with?
If you create a default hello world project with MCUXpresso SDK, do you see semihosting data being printed in PE Debug Semihosting console?

That is the exact configuration I'm using.
Also, I don't know if it matters but this is what I have in the "Debugger" tab:
When I'm running the debug session I get this for netstat -nlp
I can see the pegdbserver listening to the configured Telnet port 51794 as well as the GDBMI Port (6224), the Server Port Number (7224), and the Streaming Server Port (10224). But why is it also listening from the configured port 7224 up to the 7234 in increments of two for a total of 10 ports?
If I create a hello world with MCUXpresso the semihosting works, but this is a project with the KSDK2.0 so is not applicable, nevertheless, I wonder what is different, I would make a comparison but the code bases are completely different, also, for MQX it should work for the PEMicro the same way it does for the JLink with the same configuration. The only thing I can think of is that maybe semihosting for the PEMicro involves more changes in other header files I'm not aware of.
Could this be possible?
Thanks for helping.
Hi Manuel,
Our semihosting support relies on the project/compiler inserting a software breakpoint into a printf routine. Once the breakpoint is hit, we check whether the semi-hosting message is ready and then output it to our semi-hosting console.
We have a way to enable debug log capture, which will tell us whether this semi-hosting message is properly detected by PEmicro plugin. In order to enable it, please insert -outputdebugfile command into Server Parameter box under Debugger tab in Debug Configurations.
In order for this file to be generated, you have to make sure that the following directory in your MCUXpresso layout has corresponding write permissions: {MCUXpresso installation folder}/ide/plugins/com.pemicro.debug.gdbjtag.pne_4.1.3xxxx/lin
please run the following command to grant these permissions accordingly: sudo chmod 777 -R lin
The next time you run a debug session, you will find gdbserverdebug.out file in corresponding lin directory. Can you please email it to me for further analysis: zahar "dot" raskin "at" pemicro "dot" com.
I downloaded and installed MQX 4.1.1 to try and replicate your base setup, but could not find an eclipse MQX plugin that should help to import MQX example projects into the IDE. If this is something that you are using in your setup, can you please point me to location where this MQX plugin can be downloaded from.
Best Regards,
