Hi,
i have a problem with TWRK60N512.
I can not program the TWRK60N512 and I'm trying to unlock it with the command "unlock Kinetis" by J-Link Commander utility.
However when I connect the USB-Jlink cable, the JLink Commander tells me:
"SEGGER J-Link Commander V4.32 ('?' for help)

if I try to give the command "unlock Kinetis" the J-Link Commander tells me:

How i can resolve this problem?
