ULinkPro : Cannot access memory

Sunil Sawant

I am using ULinkPro Debugger to program and debug software on NXP LPC4088FBD144 MCU.

While downloading program in debug mode,
I am getting following error message "Cannot access memory" and "Cannot enter Debug Mode".
Downloading program on MCU is not possible.

I tried changing Max Clock frequency (all values of frequency) in
Target Driver Setup - Debug - Settings to solve the problem.
Problem not solved.

Please suggest a suitable solution to the problem.

    Sunil, it turns out it was a mistake on my end. I didn't have a proper power supply to the DUT and the current demands on reflash operations was browning out the CPU. I don't know if that will help you or not but at least it is something to check off your investigation list.
