H3-Soc boot rom security & E-Fuse on Diet-Pi

Thanks to all the good contribution. I was able to follow the instructions by @janng0 and @xeniter and got the fuses burned.

I was able to write TOC0 to SPL with the jemk script and put the SPL to my SD card and it is booting!

But...

The Bootprocess hangs after "Found device /dev/ttyS0" (i am using a dietpi image). I was using sunxi-spl.bin from git://git.denx.de/u-boot.git after checking out the same version of u-boot as in my dietpi image (2020.10) and compiling it leaving default configs in menuconfig.

 

do I need to enable more features during u-boot compilation? Where did you get your sunxi-spl.bin get from?
