I use Jlink commander "unlock kinetis" but it time out.
There's only one 4.7k pull up resistor on RESET_b but it always at 30mV.
How are you connecting the other JTAG pins?
A couple of notes:
Thanks for your notes. But when TMS is open, TMS is 3.3V. And after EZ_CS_b is left open, the RESET_b changes to 0.2V.(no longer 30mV)
Can\ you put in a drawing of your programming circuit and the different signal levels?
Attached is the circuit I use for programming to the Segger JLink Plus (should be the same connections as you use) and the Segger Needle connector:
Just a couple of notes:
Thank you. Finally, I solder a new one and it's all right. Maybe when I soldered the last one, temperature was so high and burn the chip.
Good news - keep us updated as to your ptogress!
