Hello,

 

I am using MCU MC9S12G series. The controller is already mounted on a PCB.

 

I am using a jig to flash the MCU using PEs USB BDM Multilink (6 pin).

 

The controller is part of a  pre-aged component.

The actual working voltage of the whole pcb is 24v.

 

The regulator supplies the MCU with 5V.

 

The voltages at the jig and BDM Multilink interfaces are Vdd = 5V

                                                                                Reset = 5V

                                                                                BGND = 5V

 

I am using code warrior for loading the code. The error obtained is

 

Hi-WAVE Communication to the target has failed     

(target MCU has no clock or wrong BDM clock speed is used or derivative is secured!)

 

I have set the clock.

CLKDIV: [entered value here |default 73]

 

When i try to unsecure the MCU using the unsecure command in code warrior i get the following message :

 

"Derivative could NOT be unsecured"


I am unable to flash the code.


Another team has used the same jig to flash the code on to a 12v version of the pcb having same MCU, successfully.


Can the input voltage of the jig have any effect on flashing if i am getting 5v to the mcu?


Please help.
