[H3-Soc boot rom security & E-Fuse]

Hello Team.

 

I have board based on SoC H3. Board has been damaged and after replace CPU built-in system not booting.

 

New CPU is Ok and work fine in TV-box on android.

 

I think that problem in eFUSES. In new CPU "NV2" zone is clear (0x00) but programmed in old burned CPU.

 

Please share info about simple programm of these eFUSES.
