Problem debugging FRDM-K22F in Linux with Segger J-Link OpenSDAv2.1 Firmware

sjbrech — Thu, 27 Aug 2015 14:12:53 GMT

I am using an FRDM-K22F with the Segger J-Link OpenSDAv2.1 Firmware installed (Installed the 2.1 firmware from Windows).

I am able to use KDS to debug from within Windows, but prefer to be able to debug using KDS in Linux, as that is my "normal" build/dev environment.

When the board is connected to my linux machine, I am able to see the serial connection fine, and I get serial output from the previously programmed code (programmed from KDS debugger on Windows), but when I try to launch the debugger from KDS it fails to launch successfully.

Hi Steve,

Could you tell us which Linux distribution are you using?

Have you tried using one of the alternative debug connections (OpenOCD, P&E)?

Best Regards!

Hi Carlos, thank you for the reply.

I have since resolved the issue. I ended up debugging an issue with the J-Link driver. I am not entirely sure what the problem was, but I reinstalled the driver and it started working. Unfortunately I am not sure the root cause, but I may have had an older version of the driver previously installed.

This issue is resolved (question answered).
