Hello,

while using fuse tool on u-boot I got this warning.

fuse prog 0 730 0xda3d16d3
Programming bank 0 word 0x000002da to 0xda3d16d3...
Warning: Programming fuses is an irreversible operation!
This may brick your system.
Use this command only if you are sure of what you are doing!

Really perform this fuse programming? <y/N>

 

1) My question is I need same SRK hash fuse value everytime I want to sign image for same board.

or

Is I can use other SRK hash fuse value which generated by some other CST tool to fuse on imx8qxp board.

2) Is there any way to reset these values, once we have fused it.
