I work on the imx6q,and burn the pulic key to fuse and open the secure boot function

before  I use  "fuse prog 0 6 0x2"

=> hab_status                                                                                               
                                                                                                            
Secure boot disabled                                                                                        
                                                                                                            
HAB Configuration: 0xf0, HAB State: 0x66                                                                    
No HAB Events Found! 

 

After I use the command on uboot "fuse prog 0 6 0x2"

 

But it not always bring up sucessfully

 

When it bring up sucessfully,I enter "hab_status",it show message as following

Secure boot enabled                                                                                         
                                                                                                            
HAB Configuration: 0xcc, HAB State: 0x99                                                                    
No HAB Events Found!
