niks Posted February 9 Posted February 9 Please help. Hello everyone, please help me out. I urgently need to enable secure boot on my Allwinner H3 Nanopi neo core. I tried following the instructions from the forum https://forum.armbian.com/topic/3033-h3-soc-boot-rom-security-e-fuse/#findComment-84051 . But I couldn't burn the E-Fuse. At stage 5, when loading ./sunxi-fel -v -p write 0x2000 of the compiled code and checking whether the changes were applied, sunxi-fel sid/list/version doesn't work. I have to reboot the board, and then I see no result. Please help me solve this problem and burn it so that the bootloader signature is present and it is impossible to boot from the SD card using third-party means. Please, if you have any information, help me. 0 Quote

niks Posted February 11 Author Posted February 11 (edited) I managed to burn the eFuse. Now I can load the uart0hello.sunxi file signed with toc0 and even get the "Hello H3..." output. But I can't sign the system image or even just the SPL; when I boot from them, the console is silent. Does anyone have any thoughts or know what to do? Edited February 13 by niks progress 0 Quote
