does anyone have instructions for generating images for the firefly-rk3399 board?
<tlwoerner>
it'd be nice to build my own u-boot, kernel, rootfs for rk3399, does anyone have any instructions for doing so?

is getting rather good at putting various rockchip boards into maskrom mode!! :-S
<vagrantc>
i've never gotten a build of ATF + u-boot SPL + u-boot that actually worked, but I have managed to use some tools to generate a trust.img
<vagrantc>
and have that load u-boot

once i get a working u-boot, i've usually just booted debian-installer from there

tlwoerner: this one is hard to get into maskrom mode if it is working enough to load from eMMC, but bad enough that it immediately crashes
<vagrantc>
since the boot order apparently defaults to eMMC and the only way to change that is to short the eMMC pins to ground
<vagrantc>
i've gotten it to that very bad state several times ... no i only wipe the eMMC and use microSD ... but that has some quirky issues as well
<vagrantc>
now i only..

is there a simple way to wipe eMMC using linux? i tried upgrade_tool but when i try to write sectors (ws) it fails, when i try to lower-format (lf) it fails, i can't even read sectors
