15: Target error from Commit Flash write: Ef(34): Timed-out initializing flash

[rnb]

Running LPCXpresso 8.1.4 on W10-1607.

Same above error appear on 2 developpment boards when I tried to download a new project to implement IAP

I used NXP AN11071 application note as a start base of developpment.

I had control on the boards before  (LPCXpresso) with the previous project but error appeared after the first download of IAP project. First download went well but issue start with the second download. I then realized I omit to change the CPU type in the IAP project.

I've tried both ISP and Vector catch method without success.

Anything else i can try ?

So it certainly looks like the code already loaded into flash is causing a fault before the debugger can take control. Try booting into ISP mode again - and make sure that you follow the process correctly ...

1. GND the ISP pin
2. With ISP still pulled to GND, assert RST and release RST
3. Now remove the GND to ISP pin, and start your debug session

It would also be worth trying a more recently version of LPCXpresso IDE. v8.2.x does contain some improvements that can help in this sort of situation. You can have both your current and the latest versions of the IDE installed at the same time.

Ok, Thanks for your help.

It does sound like you need to be booting into ISP mode: Regaining debug access to target MCU. What exactly did you do to try to do this on your board?

And what is your board and your target MCU? And can you clarify what you mean by "omit to change the CPU type"?

Also what debug probe are you using? And can you post the whole debug log? The Debug Log 

Finally, if you are using IAP, make sure you reserve RAM for it in your project - Reserving RAM for IAP Flash Programming

It does sound like you need to be booting into ISP mode: Regaining debug access to target MCU. What exactly did you do to try to do this on your board?

R: in order to regian vontral I tried first ISP mode (as described in Regaining debug access to target MCU) and i alsi tried to set vector catch

And what is your board and your target MCU? And can you clarify what you mean by "omit to change the CPU type"?

R: the board is a production version board (custom) with LPC1768. When I said I omit to change MCU (not CPU...sorry) I meant I did the first image download with the wrong definition of MCU settings ( in Project properties>C/C++ build). That is most likely the reason why I loss control on the board

Also what debug probe are you using? And can you post the whole debug log? The Debug Log

R: probe is LPC-LINK2

R: Yes, I will check that point. Can that be the cause of control loss ?

Hello,

Any news on the topic ?

Thanks,

René

No clue anyone ?

Maybe I was not clear, but I guess the boards were somehow affected by the wrong MCU setting. Having set the correct MCU doesn't help to regain control.

Don't know what to do

Thanks, René
