Not able to download program into mcb1700 board.Getting error msg could not stop cortex-m-Device! Please check Jtag cable
Could you have damaged the board?
Does the LPC17xx have a pin to put it in a boot mode, or other method to mass erase problematic firmware?
Check settings to use SWD, and "Connect Under Reset" options
Have you, perhaps, put the chip into some sort of "sleep" mode from which the debugger cannot wake it?
Or reconfigured the debug pins as IO ?
Or suchlike
Thank you for your reply.Problem is solved . Dont know how ,but i use another pc to download my program and it starts working. I again try it with old pc and its working.
