A good tutorial for compiling uboot.ext?

i do not know any details, i just know that is why the u-boot.ext was there ... maybe just give a mainline c4 u-boot a try and chainload that? i would not recommend to touch the legacy u-boot on the box as long as you do not know 100% what you are doing (maybe you do know 100%) as its very easy to brick a box this way due to wrong memory timings

Maybe these helps as a start:




But it looks like the u-boot.ext Balbes uses is one without de binaries from Amlogic, since he is chaining his bootloader after the boards own u-boot, so memory initialization and soc initialization is already done.
