hello, I have device running RK3128A, but the bootloader is old as version 2.34. I am trying to create latest bootloader with this chip. I use rkbin to creat bootloader using RK3128 chip. but it doesnt boot to loader mode. always maskrom mode after bootloader flashing. and anothing thing, this rk3128a the rsa key is 2048 to sign the bootloader, the problem is different way to sign the bootloader, I tried secureboottool version 1.85, v1.90 and v1.94 even rk_sign_tool i use, but the rsa key is different than the original. when I flash this bootloader the device cannot enter into loader mode. after flahed it was in masrom mode again. I tried to select those chips on rk_sign_tool and secureboottool one by one to sign the rk3128a bootloader to rsa key 2048 but all chips never boot to loader mode, always maskrom mode. what kind of sign do I need to use for RK3128A? and last question what is the meaning of (L) in miniloader eg. rk3128miniloader(L)_v2.37.bin? thanks in advance!
