I tried programming the LPC 1114 board in LPCXpresso with my own blinky program. I am a fresh beginner. I have debugged the example projects successfully on the board. but i think there should have been some problem in the project i created. Now when i debug the example programs also it throws an error message

"15:target error from commit flash write: Et:flash driver not ready."

erasing the flash also dint help.

#1 It's not unusual that debug connection fails. Often it's enough to stop debug session and reconnect USB.

#2 Sometimes that doesn't work and it's necessary to switch in ISP mode and start a debug session while LPC is in ISP mode.

#3 On rare occasions even that fails and then your last hope is to program via ISP with FlashMagic.

#4 Of course, if you have enabled a CRP (Code Read Protect) level which doesn't allow you to erase the chip again, you're not able to reprogram it with LPC-link or FlashMagic.

#5 I don't know what's dying first, LPC-link or target board. I never killed one of them or my own boards and never tried to kill them (not until I'm getting paid for that :eek:).

#6 Therefore I don't think you have killed your board or LPC-link and at least FlashMagic will erase it again :)

See: http://support.code-red-tech.com/CodeRedWiki/CommitFlashWrite

Try: http://support.code-red-tech.com/CodeRedWiki/DebugAccessChip

So check your USB and USB cable. If enabling vector catch and switching to ISP fails, your last hope is using Flashmagic via ISP :)

If that fails, your LPC is protected or dead :eek:
