Hi,

I setup OpenOCD with the LPC4330 and external SPIFI flash. Works nicely with the JLLINK firmware on the LPCLink2.
There is just one problem, I am unable to reset the CPU using the hardware reset signal (SRST).

Whenever I setup OpenOCD to assert the SRST line, nothing happens.

I tracked it down in the OpenOCD, it actually sends a commands 0xDC and 0xDD to the USB. But nothing happens on the SRST line.
It not broken, the CMSIS_DAP firmware can switch it. I also checked behind the bidirectional buffer, also no activity.

So now I am seeking an answer: does it make sense for me to search on on my side, or is this simply a llimitation or bug of the JLINK firmware for LPCLink2?

Thanks,
Simon
