LPC4337 and j-link programing

[ali_asadzadeh]

Hi,
As you may know the LPC43XX with internal flash needs a signature or some kind of CRC generation in the execution image,I'm using keil as my tool and j-link as my debugger. the problem is that everything works exactly fine when I flash the code and use j-link for debugging. but when I re-power the board it would not boot up. when I use flash magic to flash the code and tick the activate the flash bank the MCU would boot up after re-powering. I think the keil has the option to generate the signature but I do not know how to resolve the problem. do you have any idea?
