Hello all,
I directly copied and pasted the bin file to the board at that time still can be recongnized as a tty interface. However, after status led flashed quickly and I unplugged and plugged the cable again, the tty interface has gone. Also if now I use the Xpresso IDE to flash some other axf to the board. It would show probe cannot be found.
Anyone knows how to get the usb driver back? Thanks a lot.
But it still appears as the bootloader driver,
Solved! Go to Solution.
I purchased a new jlink mini edu from segger and then attached it to J19 of the board (FRDM-KL82Z) and I tried it on SWG interface. All the problems are gone.
Thank you!
Right, I tried it on J19. The error output about connection is slightly different, something like 'encouter error while accessing to MDM-AP'. And if I continue with 'unlock kinetis', it gives the same error message as I previously posted.
