Here:
http://wiki.t-firefly.com/en/Firefly-RK3399/flash-image.html
are the instructions for flashing the RK3399. They talk about files called boot.img, kernel.img, system.img, recovery.img, misc.img, resource.img, bootloader.bin, trust.img, and finally update.img. When flashing the RK3399 with a GPT partitions you use, what appears to be, ENV variables, like $LOADER. Undefined variables in bash have a the empty string "" or the value of 0.
What are these .img and .bin files?
How do I create them?
What are these ENV variables?
What do I set them to?
Thanks!
