Here is the step-by-step to boot to U-Boot on px30.
|
||
|
|
|
||
|
|
Get the Source and build ATF binary
|
||
|
|
===================================
|
||
|
|
|
||
|
|
> git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
|
||
|
|
|
||
|
|
Compile the ATF
|
||
|
|
===============
|
||
|
|
|
||
|
|
> cd trusted-firmware-a
|
||
|
|
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=px30 bl31
|
||
|
|
> cp build/px30/release/bl31/bl31.elf ../u-boot/bl31.elf
|
||
|
|
|
||
|
|
Compile the U-Boot
|
||
|
|
==================
|
||
|
|
|
||
|
|
> cd ../u-boot
|
||
|
|
> make CROSS_COMPILE=aarch64-linux-gnu- ringneck-px30_defconfig all
|
||
|
|
|
||
|
|
Flash the image
|
||
|
|
===============
|
||
|
|
|
||
|
|
Copy u-boot-rockchip.bin to offset 32k for SD/eMMC.
|
||
|
|
|
||
|
|
SD-Card
|
||
|
|
-------
|
||
|
|
|
||
|
|
> dd if=u-boot-rockchip.bin of=/dev/sdb seek=64
|
||
|
|
|
||
|
|
eMMC
|
||
|
|
----
|
||
|
|
|
||
|
|
rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
|
||
|
|
help of the Rockchip loader binary.
