LPC11U34F not responding - Cannot provide power to DAP bus.

Hello, I am trying to debug the firmware for a custom board using the LPC11U34F, using the MCU-LINK debugger. It worked fine for three tries, then stopped working.

When I try to debug, I get the following errors:

Error 1:

"Failed to execute MI command:

-target-select extended-remote | crt_emu_cm_redlink -msg-port=1093 -g -mi -2 -pLPC11U14/201 -vendor=NXP --reset= -ProbeHandle=1 -CoreIndex=0 --flash-hashing --flash-driver LPC11_12_13_32K_4K.cfx --telnet 3333

Error message from debugger back end:

Remote communication error. Target disconnected.: No error.

Error 2:

Error 3:

I can't erase the firmware using Flash Magic either.

Do you have any suggestions or questions?

Thank you for your time!

Please try follows:

1. create a new workspace

2. create a new project under this workspace

3. the board connects computer in ISP mode

4. try debug

How does it work?

If still fails, reinstall MCU-Link driver with this guide then do step 1-4 again.

Hope this helps,
