I'm trying to disable the JTAG on MPC5567.
I've tried to erase the shadow flash : The MCU no longer boot from internal flash ( Bootcfg = 0 0 )
Changing the shadow flash y JTAG doesn't work well ( get several part bricked trying to change the shadow flash with a Cyclone tool)
1) Reading the 55667RM doesn't explain why MCU doesn't start when the shadow flash has been erased ( it does on 5644A)
2) What shall really be changed to secure the MCU ? ( block the JTAG to avoid a reading of the internal flash)
