Hello,

I am going nuts in programming a simple LED blinky project to external flash on a LPC-link2 board.
The board detects fine and is programmed by the LPCXpresso IDE as a Red-link probe.
But when I try to program the .axf file generated by the IDE, i always get the following error and programming fails:

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Ni: LPCXpresso RedlinkMulti Driver v7.5 (Oct 24 2014 22:17:31 - crt_emu_cm_redlink.exe build 172)

I am following the steps as mentioned in the following link:

Please guide me as to what am doing wrong.

Thanks,

I tried the above link but no good.
One more insight is that I am able to program the LPC-Link 2 board with the configuration tool which I guess programs the external flash with various debugger images.

Thanks

The error means the debugger cannot see you target, implying it is in a strange state. Programming different images into the lpc-link2 will not help in any way - you need to fix your target.

I understand but the thing is that I am using the single LPC-Link 2 board only. I also want to understand if its ok to do it.
I mean that it is not mandatory to use the link 2 to program another LPC board only?
I hope there is no JTAG/SWD connecting cable to be connected when link2 external flash needs to be programmed?

Thanks

So, you are using a link2 board as a target. Therefor you need another to work as the debug probe.

Yes, I also think so.
I guess there is no way to program the external flash on a single link2 board via PC using the LPCxpresso IDE....
Just confirm once if you have an idea.

Thanks,
