LPC1857 does not come out of ISP MODE

Hi all,

I am new to NXP, i am using MCB1800 for LPC1857.

I am trying to download code into internal flash memory with the help of Flash Magic it seems to be working fine.

I have set all boot jumper to low position for booting from internal flash.

But after downloading program at every time when i send ? to uart i get Synchronized message back it seems like my board does not come out of ISP mode.

Please help me to come out of ISP mode and program internal flash memory.

Regards,
Lalit Shah
