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:

Error message from debugger back end:

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

Do you have any suggestions or questions?

Thank you for your time!

Hi

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,
