Hello,
many ARM SoCs have a mask rom feature that provides interface for
downloading firmware over USB.
Downstream rockchip u-boot has 'brom' or 'rbrom' command for this
purpose, and downstream sunxi u-boot provides 'efex' command. p-boot has
code for entering FEL on A64 SoC.
With this patch I am able to activate the USB downloader on a rk3399 but
the rkflashtool fails to communicate with the device. On a H2+ I can get
into the FEL mode and get flash parameters. YMMV
I don't have any great idea how to structure this so that the command
does not need platform-specific code. Is there an example of a command
that has platform-specific implementations?
Thanks
Michal
