I have an issue for download the image:
02:failed to connect: Ep(0). target marked as not debugabble
i tried already all the possible solution for it in the related topics in the below link :
1-Regaining debug access to target MCU 
but it is not solved the problem
that is the log from the flashing :

Nc: Serial Number: HID64HS12

Hi,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Maybe you should consider this issue is related to the hardware, so I was wondering if you can introduce which board and demo code you use for the testing.
Have a great day,
TIC

My board is LPC 1769 connected it to LPCxpresso IDE through USB , i tried first to flash a program that make led blinks and give me that message while flashing "02:failed to connect: Ep(0). target marked as not debugabble" .
Then i tried a simple program   While(1){i++;}  . and still the the same message exist .

Hi,
Thanks for your reply.
Whether your board is OM13085 (LPCXpreeso 1769 board), if not, I was wondering if you can share the schematic of the board and I can review it for you.
Have a great day,
TIC
