Unable to Debug FRDM-KL28Z board

[talledo]

Hi

While I can debug OK with a different PC. I have a fresh MCUXpresso installed on a different PC. I connect my FRDM-KL28Z board but I am not able to debug. I get the following:

MCUXpresso IDE RedlinkMulti Driver v11.1 (Feb 24 2020 13:54:38 - crt_emu_cm_redlink build 11)
Found part description in XML file MKL28Z7_internal.xml
Reconnected to existing LinkServer process.

The difference when I connect to the non working PC. Windows 10 shows a mbed Serial Port  while when I connect to the good PC, that driver is not shown when I connect the FRDM-KL28z board.

Any suggestions?

Hi,

1.Check your Dap driver on computer .

2.Check your signature on computer

3.update your opensda

You can check and troubleshoot according above options.
