The program download using jlink failed on S32K144

[103]

The program download using jlink failed on S32K144: At first, it downloaded normally, but then suddenly it couldn't download anymore. After unlocking the chip, it could work normally. After using it for a while, it couldn't download again. I changed the download method on the S32DS from JTAG to SWD, and it worked again. After using it for a while, it couldn't download again. This time, I don't know what to do. The same program and downloader can be used to download on another board. I want to know how to restore the download and ask under what circumstances a good chip suddenly stops downloading.

Hi @103 

Can you please contact SEGGER support? It looks like the issue might be related to the J-Link debugger, and their team should be able to help you troubleshoot it more thoroughly.

Thank you very much for your reply. I have found the problem. It's that the download cable is broken.
