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!
what is the reason about this
Hi y liuhao
one can recheck hardware (clocks and power supplies) using

But I work on the same board and with same uboot
The uboot can bring up sucessfully everytime
But If I use the command fuse prog 0 6 0x2
It only bring up 1 or 2 times in 20
In my mind it may be depend on the boot mode or fuse config
if - "It only bring up 1 or 2 times in 20" - this may be caused
by hardware problems too.
