Hi,

I think i made a serious false decision. I was messing around with the Watch Dog Timer and i think, it worked in the end.

Then I took the hardfaulthandler from the cr_startup_lpc11.c and put it into the main.c, added a comment and a GPIO-command to light up the onboard LED to indicate the occurance of serious error. I thought, because it is declared as WEAK, this is no problem.

But apparantly that was a very bad idea. I cannot enter debug mode anymore. I get this error:

15:Target error from Commit Flash write : Et: Flash driver not ready.

This is from the info bar:
Thread [1] (Suspended: Signal 'SIGINT' received. Description: Interrupt.)
    4 <symbol is not available> 0xfffffffe
    3 <signal handler called>() 0xfffffff9
    2 <symbol is not available> 0xb87c9362
    1 I2CInit() i2c.c:332 0x00001310

How do I recover my LPCXpresso-Board? :(

Like the rest of the world:

Read this: http://www.support.code-red-tech.com/CodeRedWiki/DebugAccessChip

Then enable 'Vector catch' and switch to ISP :rolleyes:

If that's not working, use UART and FlashMagic :eek:

This chips are not easy to destroy, so don't panic too early ;)
