I have heard someone said that USBMULTILINKBDM isn't full function in 9S12 debugging, in some case, when the chip was in wrong BDM status, the USBMULTILINKBDM can't connect to the target board,need the cyclone to renable the chip for USBMULTILINKBDM connecting, I am confused to this problem,I have encountered several times,

Could you please to expound?

Hi:

In some conditions or if you explicitly do so, the HCS12 becomes 'secured' and the USB BDM cannot communicate anymore. In that case you need to use the 'unsecure12' program to unsecure the device. After that, the BMD will recognize it again.

You can download the unsecure12 program from the P&E Micro website.
