I did followed everything through your video tutorial. The D4-D7 and D2 not blinking. Can advise for further troubleshooting?

Hi

Is there any download error still? If you haven't downloaded code successfully, it's not possible 

If fail download code, try update on board debug firmware with LPCScrypt.

try CMSIS-DAP first. If still fail, try Segger Jlink

Hi,

I have to use the second option of debug to prevent the error from coming out. You may see the  debugging on the right side (Blue highlighted sentence).

Is there any chance, you may provide some tutorials video to troubleshoot the problem using LPCScrypt? While in the meantime, i will tryout your ideas to troubleshoot the problem.

Hi 

I suggest you trying if IDE can connect board in ISP mode. press ISP button(SW2) on demo board when PC connects board with USB cable. To avoid old project/workspace association, test the project with a NEW project and NEW workspace.

If fail connect in ISP mode, update on board firmware with LPCScrypt, Here is LPCScrypt video and user guide.

Hi vawn90

Do you use demo board or own PCB?

What interface or emulator do you use?

What is the IDE?

How does it work if you create a NEW project in a NEW workspace?

Thanks,

Hi Zhang,

I use the board as attached.
Im using MCUXpresso IDE. I'm using the example library from LPCOpen to try it. And the error came out after that.

HI vawn90

I tested lpcopen blinky project, there is no issue. below photo is my board setting. Attached is my testing video of PC side. I use MCUXPresso IDE 11.3.0
