Lpc2000

Hey guys,

I recently mentioned a problem where the Philips Flash utility 
partially works with my lpc2114 board and gives communication errors 
whenever attempting to Erase Flash or Download code to the board. 

I troubleshooted the RS232 interface, and all rs232 signals are 
working OK now, but I still get comm errors with the Phillps 
Utility. I think that I'm possibly dealing with a more serious 
problem here, as I can't even download code into flash memory of the 
same board thru the JTAG interface. 

I sometimes use the Debug Utility in the IAR Software as an 
alternative to flash program and debug applications on the lpc2114 
chip. This surely works. However, the above method didn't even work 
with the same board. The IAR flash programming tool executed 
normally while downloading code unto the board. However afterwards, 
the memory dump showed no sign that the flash memory got programmed. 
The application's memory area showed nothing but 1's or 0xFF's, 
while the reset vectors supposedly points to the bootloader and not 
the application.

Let me know what you think. I think that I'm possibly dealing with a 
corrupted chip.
