How to programming with LPC Link2

hans1234569 — Wed, 16 Sep 2020 03:00:02 GMT

Hi all,

I am new to LPC Controller, and I am trying to program LPC5516 chip with LPC Link2.

I have already configured the LPC Link2 to J-link mode, but when I connected to my own built board with SW, Link2 can not recognize it.

So I check the user manual & datasheet, then they relate the ISP Mode can use for flash programming, and I refer to LPC55s16 - EVK then do it the same method, but still like before.

Is there something I should noticed about?

Hope anyone can help,I`ll appreciate.

Really thanks~

Hi.

If you use custom PCB, check if the debug interface is well designed:

To identify the problem on debug probe or MCU board, test your LPC-Link2 with another board, can it connect successfully?

If your LPC-Link2 has no problem, test the MCU board in ISP mode. create a NEW project with a NEW workspace, see if it can be connected?

Have a nice day

Hi @ZhangJennie ,

Thanks for your reply!

Here is Keil C debug function setting, it can connector to LPC Link2 but LPC5516 not.

From LPC55S16 - EVK

It says how to force in ISP Mode

I have no ideal about this method is correct or not.

Do you have some suggestions for reference?

Thanks again for your help!

So you use LPC55S69 EVK board. with this board, to enter ISP mode, press ISP button as I show below, then connect board with PC. try if you can connect board now. Make sure you use a new project in a new workspace.

If can't connect board in ISP mode, update the on board debug firmware with LPCScrypt

the training of how to use this tool is posted on this link.

hi，

I meet the same question as you mentioned. I tested on LPC55s69-EVK successfully, but failed on LPC55s16-EVK.
