I cannot find JLink Port in KDS PEMicro Debugger

[gloria]

I follow the instruction and JLink CDC UART Port can be seen in device manager. However, I cannot find it in KDS PEMicro Debugger. Could you kindly help me about this?

One more question: I am using KDSK example -- gpio-example-frdmk64f. Why both 'debug' one and 'release' one are included in every type of debbugers? What are the differences between 'debug' and 'release'?

Thanks in advance!

Dear Qingyuan Meng,

please, if you use J-Link, set please DBG SEGGER J-Link Debugging not PEMicro.

I hope it helps you,

Thanks Iva. If I want to use PEMicro, what change could I do? I use the frdm-k64f board. are these three buggers all avaliable for this board? Many thanks!

Hello gloria,

sure - if you want to use PEMicro, you should install OpenSDA from websites P&E Microcomputer Systems

and load new firmware.

Please, don ´t forget to following steps for loading :

1.Unplug the USB cable (if attached)

2.Press and hold the Reset button.

3. Plug in a USB cable from a USB Host to the OpenSDA USB port.

4. Release the RESET/Bootloader button.

5. A removable drive will be visible in the host file system with a volume label of BOOTLOADER

For more details you can visit OpenSDA User´s Guide​ or very useful could be also

I hope it helps,
