Is there anyone who familiar with H3's secure boot?

 

I've got an ott box recently, with 1GB RAM, 8GB eMMC, H3 soc, wifi module is RTL8189FTV.

 

I try to use sunxi's tools FEL to boot, but not succeed. But the nanopi-M1 board can be booted up with FEL.

 

when change the u-boot-SPL's textbase, and set it to SRAM-C's space-0x10000. FEL can download the spl and execute it.

The SPL init  the DDR. Then download and execute u-boot. u-boot can run, but cannot reach cmdline.

 

the datasheet shows that H3 support secure boot feature, but I can't find any documentation about  this.

 

Through the H3's SDK, I got some information about sbrom.

I still wonder how to set the soc to enable secure boot. I read back the soc's brom and disassemble it, but have not found the answer yet.

Which device is this? Beelink X2 (which uses RTL8189ETV with newest PCB rev) needs a standards violating type-A-to-type-A USB cable to allow FEL boot and on devices with eMMC FEL mode has to be entered manually (X2 having a FEL button)

 

BTW: best place to ask such questions is linux-sunxi IRC

No problem to enter FEL mode. 

Just the chip is set to secure boot mode, so myself u-boot-spl can't run directly.

 

the device is a chinese tv box board, model is "inphic i7".
