Hi!

I need to flash/program and debug custom PCB with ARM Cortex M0 (LPC11C24) on board.

I have required JTAG pins, but I don't know how connect them to my
computer and flash/debug my programs.

Do you have some advices and which of your products could I use?

Thanks a lot!

LPC11C24 is not supporting JTAG :O

The simplest way to debug/flash your 11C24 is a LPC-Link2.

It's working without problems with LPC11C24 and a simple SWD connection (and faster than a LPC-Link)....

HO... ok!

Thank you for your answer and your links!! I will try LPC-Link2.

Do you have any idea how to use it with archlinux?

It's a good idea to use LPCXpresso & Link2.

User Guide is talking about supported Linux versions:

• Linux – Ubuntu 11 onwards
• Linux – Fedora 17 onwards

Other distributions may run or not...

Thanks! but...

I used to use LPCXpresso, but I had several problems with. So to be indepedant and have the mastering of all the process, I program the LPC11C24 with my own crosscompilation, I used crosstool-ng to create it. Currently I use the UART to flash but I can't debug and that's not the easiest way to flash. It's for these reasons I would like use the SWD but without the constraint of LPCXpresso.

And how do you debug?

That's a good question. I don't know yet, but I know that some solutions exist.
