Hello,
I've made an LPC11C22 prototype board and I'm trying to debug the blinky project on it. I have an LPC11C24 dev board , and I'm using the lpc-link (with traces between the lpc-link and LPC11C24 cut) to debug my new board , the only chage i've made to the blinky project was changing the MCU family from LPC11C24 to LPC11C22. after showing the 100% download the debugger seems to hang on. I tried to suspend it and then clicked "step over" I got this error :
target request failed: cannot find bounds of current function
do I need to change something in the settings ?

and now this errors :
15: Target error from Commit Flash write: Et: Flash driver not ready.

16: Target error from status-poll
Lost Debug Control.

Changing MCU setting is all what's needed :)

#1 Switch to ISP and try to debug again http://support.code-red-tech.com/CodeRedWiki/DebugAccessChip

If that fails:

#2 Switch to ISP (UART) and try FlashMagic

If that fails: Your hardware is faulty :eek:

well I've found the problem. my ISP pin doesnt have a pull-up resistor ! letting this pin floating forces the uC to enter ISP mode when the LPC-link tries to reset the target ! pulling this pin up with 33K resistor seems to resolve the problem . :D

If you also use a RESET pullup I would recommend to use a lower ISP pullup like 10k :rolleyes:

hmmm yes I use RESET pullup with a capacitor. I will change it to a 10K. just in case :cool:
thanks Zero for your help !!
