I'm not sure how to go about this, the JTAG device is not being detected

[adityap7]

I'm using the LPC4370-FET100 MCU on a NHS3100 development board. 

I've followed the instructions to debug the example 'blinky' project given on the IDE user guide pdf, but I'm facing the error where the JTAG device is not found. 

The debug emulator was automatically found in the previous step: LPC-LINK2 CMSIS-DAP V5.173

The blinky project was downloaded from LPCOpen for the the 4370 mcu. 

I have attached a snippet of the issue to this post. 

Any help is greatly appreciated. I don't have too much experience with interfacing microcontrollers, and it's been a while working with one.

The LPC4370 on this board is acting as a debugger bridge chip, in order to debug the microcontroller in the NHS3100. It works as a JTAG debugger with the right firmware, the CMSIS-DAP firmware mentioned above.

If you loaded a blinky example into the LPC4370 environemnt instead of the CMSIS-DAP firmware, then you simple do not have a debugger anymore, but a microcontroller doing a blinky.

If you are interested to use this board a s an LPC4370 board, then you need to have an external debugger bridge like the mentioned LINK-2 board, which itself has an LPC4370 on it :-)

Bernhard.

Hello Adtiya,

Please open a new IDE workspace, then import LPCopen lib and a simple demo,

Build it , then refer to my attachment to debug.

If still can’t work , please tell me your board, which debugger do you used? LPC link2?

Also take video or screenshot show your steps.

Have a great day,
TIC
