Dear Sir,

I want to use backdoor key to unsecure 87xx. 

But I got an issue to run the code.

 

I added the code to unsecure device. But it will crash to write the compared backdoorkey.

FCNFG= FCNFG_KEYACC_MASK;
vfnFlashWrite(0xFFB0, (const UINT8*)au8BackDoorKey, N_ELEMENTS(au8BackDoorKey)); --> crash here
FCNFG= 0;

 

Please help me to check where the issue is. Attached is my code.

 

 

Thanks.

BR,

Sean
