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.

Make sure you follow the debug design in this FAQ. Provided you have followed these and provided power it should work

Ps note that lpc810 does not have jtag. It is swd only.

Oh, Thank you for reply.

I solved the problem, and I upload my program on LPC 812 chip sucessfully,

thanks to you.

Thank you again for your support!
