LPC2000 ISP error: File compare failed

[CHOOBK]

I am using ET-ARM board. I tried to download a hex file. Its downloaded successfully, however when I tried to compare Flash, it threw an error " File Campare failed" I have tried with 2 computers, one with USB link, the other with serial port, both results are identical. Any suggestions?

If you've encountered this kind of error using the Philips ISP utility then read this:

The LPC family has a check for valid code implemented when the code is valid the chesum is written to an unused address in the interrupt vector table, I think it was addr. 14.
The ISP utility calculates that checksum and enters it into the code before programming it. Check the lpc2000 Forum for more details.

Do you have the manual ?
it is have using LPC2000 Flash Utility.

I believe the only feature provided by LPC200 Flash Utility that is not quite evident is "Use DTR/RTS for Reset and Boot Loader selection"
Reading of Philips application note AN10302 will help you understand how to get into ISP mode either manual or using DTR/RTS signals of the PC serial port.
