Hi everyone,

I have been using a Hitex 4350 board with an lpc link2 debugger for a while now.

 

This morning, I have noticed that I am no longer able to debug my code. On Sunday, it still worked and there was no code modification afterwards. The failure outputs the following error message:

 

Debug protocol: JTAG. RTCK: Disabled. Vector catch: Disabled.

I found that this problem may be related to the lpc link2 being somewhat in a bad state. I therefore also ran the following command:

lpccript queryflash

The out put is:

Error opening COM5: Read Timeout
Error: <Command line>:0: Read Timeout
   Script cmd:      batchmode 1
   Last target cmd: =print 25888
Terminated with errors

Is there any explanation for this behavior or is that lpc link2 just broken?

 

Thank you and best regards
