MCU Express IDE doesn't recognise CMSIS - DAP debug probe LPC Link2.

[abhijitkatkar]

Hi,

I am trying to run #PN7462 Examples using the OM27462 Development Kit on #MCU Express IDE. For debugging I use LPC Link2 debug probe. I also use #LPC Scrypt to update the firmware of debug probe. However, just for the first time, the IDE detects CMSIS - DAP debug probe, it doesn't recognize the probe after first time. I tried debugging the PN27462U_ex_phExMain example, but LEDs are not glowing or the board is not going in the polling mode. I also tried running other examples, and I am facing the same issue.

May i know the right way to use the debug probe. I also tried flashing the binary file on the board in SWD mode, still the code is not running.

Thank you,

Abhijit

Hi Abhijit，

For CMSIS-DAP, the Windows driver package if not already installed – for example by LPCXpresso IDE – can be found at:

In addition, there is a small possibility that an incompatible driver may be selected. For more details of this issue and fix, please see the FAQ below:

You may also update its firmware to act as a j-link debug probe and check if it works on your side. Please refer to https://www.nxp.com/docs/en/supporting-information/Debug_Probe_Firmware_Programming.pdf for more details.

Hope that helps,

Have a great day,
Kan
