** [tickets:#255] LPC-Link2 Not Working as CMSIS-DAP**
**Status:** new
**Milestone:** 0.9.0
**Created:** Mon Nov 04, 2019 01:35 AM UTC by Donald Bailey

Hi,
I'm working on a project with the NXP LPC824 using VisualGDB and OpenOCD. Using
the LPCXpresso824-MAX dev board I had no trouble programming and debugging
using OpenOCD. I have recently built my first prototype PCB for this project
and purchased an LPC-Link2 to use as a CMSIS-DAP debugger with it. However, I
am unable to get the LPC-Link2 to work with OpenOCD. I keep getting a
"CMSIS-DAP command CMD_INFO failed" error.
I have flashed the CMSIS-DAP firmware to the LPC-Link2, reinstalled the
drivers, and followed any other troubleshooting tips I could find, but with no
success. The LPC-Link2 works when flashed with the Segger J-Link firmware and
also with the CMSIS-DAP firmware when debugging through MCUXpresso, so it does
not appear to be a problem with the probe or the firmware but rather something
specific to OpenOCD. There is nothing wrong with the target board because, as a
workaround, I have removed the target MCU from the LPCXpresso824-MAX and am
using its external debug header to debug the target MCU on my PCB.
I am using the version of OpenOCD that comes with VisualGDB (0.10.0) but I have
also tried the 0.10.0 version that is from the MSYS2 repositories I am on
Windows 10.
Here is the output of my version of OpenOCD with the LPC-Link2 with debug
turned on.
```

Any ideas? I have tried the NXP forums and StackExchange but noone seems to
know anything.
