Lpc2000

Hello,

I am using LPC2124 and WinARM compiler/linker for the same. I 
herewith facing a problem see if anybody can help resolving the 
problem.

Problem:
I wrote a very simple program to switch on and off the led which is 
connected to LPC2124's port pin with pull-up. My compiling message 
does not gave any error. I uploaded the hex code to LPC2124 using 
the philips standard ISP tool ( which i got it from philips site). 
In the ISP exe, i tried the RUN from address &00000000, it is 
running but changing the jumper options to run mode and resetting 
the hardware fails to run the same. When i went through the doc. i 
got the clue that addr. &00000014 location should contain the 
checksum value in 2's complement, otherwise the program switchs to 
boot loader mode even though it is in run mode. I am using the 
makefile which is available in the samples of winARM directory.

Please do the give needful info.

Thanks 

regards,
