Error launching Debug\adc.axf

Hello,

I'm new to programming with the lpcxpresso board (lpc1343) and was testing the adc example that was provided.

I was trying to modify it to poll rather than use interrupt, and removed the #ifdef __JTAG_DISABLED and the #ifdef __SWD_DISABLED check to see what would happen.

Since then, I am not able to debug any programs, and get the following error message:

Error Launching Debug\adc.axf
02: Failed on connect: Ee(07). Bad ACK returned from status - wire error.:

My question now is, how can I "reset" all registers so that I can debug programs again?

I thought I could use the reset value for the ADC IN0-4 pins, but I dont know how to run the code without the compiler (would that do it?).

Many thanks,
Navid

With deleting #ifdef __SWD_DISABLED you have sucessfully disabled SWD :eek::eek:,

so switch to ISP as described in:

http://support.code-red-tech.com/CodeRedWiki/DebugAccessChipccessChip

#ifdef __SWD_DISABLED
  LPC_IOCON->SWDIO_PIO1_3   &= ~0x8F;    
  LPC_IOCON->SWDIO_PIO1_3   |= 0x02;  /* ADC IN4 */
#endif

Note: PIO1_3 (pin 39)  is used for debugging (SWDIO). If you switch it's function to AD4, your Debug connection isn't working any more.
