LPC4337: 15: Target error from Commit Flash write (but flash programmer works!)

Hello,

I'm developing since a few months on the LPC4337 (Win7, LPCX v8.1.4, LPC-LINK2).

I'm facing a new debug problem that I can't understand.

I use internal FLASH as program flash, not a QSPI.

When I try to upload and debug the firmware (@ address 1A000000), I have the following error during the download (it seems that a part of the firmware is well downloaded) :

  15: Target error from Commit Flash write
  System rejected access at location 0x10084FE0 - verify Population of memory and peripherals

First I never ask to upload the firmware at this memory location, second the strange things is when I use the flash programmer, everything works fine (but it's not a long term option for me, I want to debug!).
The firmware is about 190kB.

What I've tried so far:
- Vector catch (false/true)
- Restart LPCXPresso
- Delete Debug config
- Erase flash before debugging
- reboot computer

Can you help me?

Ow man, that was indeed the problem. I removed some (new) other USB powered hardware from my desktop PC and it works!
WTF, a desktop PC that can't supply enough power to USB ports! Perhaps it's the other peripherals (Peak CAN adapter and Peak key ?).

Anyway, thanks a lot

Check your power. This sort of error is normally caused when the power drops as you program the flash (which takes a LOT).
