Hi.

 

I'm trying to upload some program on LPC812 directly(no development board) using LPCXpresso.

 

So, I connect LPC-Link1 to LPC812 like below :

Now, I solder LPC812 on a breadboard and there is nothing wrong in the circuit.

 

I connect LPC-Link1 to LPC812 not only SWDIO method but also J-TAG method.

 

So, I connect TDO_SWOX pin to No.19 pin of LPC812 and TDIX pin to No.12 of MCU.

 

When I try to upload and debug in LPCXpresso, but, it can't find target(LPC812) device.

 

Both SWDIO method and J-TAG method failed to find target device.

 

I make new workspace and import LPCOpen LPC812 library.

 

And, I add #define NO_BOARD_LIB in top of C project.

 

If I upload some program on a LPC mcu, Should I edit some setting in LPCXpresso IDE?

 

Thank you.
