Programming LPC1227 via LPC-Link2

Discussion created by Ugur Kebir on Oct 13, 2017

Hello,

 

I try to load program LPC1227 wit use LPC-Link2 . I followed the instructions, but I got an connection error. LPCXpresso IDE can see LPC-Link2 but LPC-Link2 can not see LPC1227 MCU. So I took Connection failed to MCU error.

 

Extra Info: When I try to connect the LPC1227, Against the possibility of making mistakes I try all JP1 and JP2 position combinations. But it is not working...

 

* I successfully installed LPC-Link2.

 

* LPCXpresso IDE see LPC-Link2

 

 

*Got error failed on connect

 

 

 

* Debug error due to connection failure

 

 

 

 

 

Possible error possibilities:

My Debug configurations may be incorrect. When I checked the boot debug probe, I noticed that the probe was LinkServer. Is it correct?

 

 

*I am absolutely sure that the MCU is working because I have already programmed it via LPCXpresso with Jlink Segger.

But now I want to upload program with use LPC-Link2. I initially connect the ISP pin to GND. Then I take it back to switch debug mode the LPC1227. Maybe I'm making a mistake at this point.

 

Do you have any idea about the connection failure?
