Hi, thank you for your reply. I thought this will work as normal openSDA debugger, in which i will put firmware (same as for K20 on eval board) and will work, but unfortunatelly it's not - compared to K20 on eval-board it has only 64 kb bootloader memory, and k20 has 128 MB! I tried to drag-and-drop hex file through that programmer, but it outputs fail :
The interface firmware FAILED to download the flash programming algorithms to the target MCU
