Hello,
This might be a stupid problem on my end, but after I program the lpcxpresso 1769 using the Program Flash utility provided by the LPCxpresso eclipse ide, reset the power, the program doesn't seem to hold in flash memory. Nothing runs..It doesn't work after power reset (physically unplugging USB cable and plugging it back in)

Any help will be appreciated..
Thank you
Nav

Are you sure your (custom?) board isn't booting into ISP?

Thanks for the replies guys..
I've been running in debug mode for last two months and the program runs fine. Even right after flashing the chip using program flash utility the program runs. But it doesn't run after I do a power reset.
BUT...I found the problem. after resetting the power I have to Manually reset the mcu by shorting the reset pin to ground pin a second, then the program starts to run.. Is there a work around for this?

Thank you, Nav

Hello nav,

without to have more detail (in particular the source code) it's hard to tell you where is the problem.

Also, my opinion it is that you have a software issue.

So, please give  us more details related  to this issue .

I suspect that your program is crashing. You will need to debug your program to find out why.

You can attach to a running system by using the Attach option in the debug configuration.
