Rockchip Rk3328 / ROCK64

This configuration package pine64/rock64 compiles a Skiff base operating system for a ROCK64 or similar rk3328 board.

Getting Started

Set the comma-separated SKIFF_CONFIG variable:

$ export SKIFF_CONFIG=pine64/rock64,core/gentoo
$ make configure                   # configure the system
$ make compile                     # build the system

Once the build is complete, it's time to flash the system.

Flashing

Skiff is easiest installed to a SD card.

Note: you may want to follow the "Erase SPI" steps below first.

These commands require root and may need to be run with sudo bash.

export SKIFF_WORKSPACE=myworkspace
export PINE64_SD=/dev/sdx # make sure this is correct - i.e. /dev/sdb
make cmd/pine64/common/format
make cmd/pine64/common/install

The "format" command creates the partition layout and installs u-boot. This only needs to be run once. The "install" command copies the latest Image, dtb, boot script, initramfs, and modules image to the boot and rootfs partitions. The root system can be updated without touching the "persist" partition by running "install" again whenever necessary.

SPI

There is SPI memory which can be flashed with u-boot to provide additional boot options without a SD card connected. You may want to erase this SPI to be sure that the u-boot from Buildroot / SkiffOS is used, or flash an updated u-boot.

The ayufan docs for this process are available.

Erase the SPI

Erasing the SPI contents will ensure that the u-boot from the SD card is used.

To zero the SPI, download the ayufan u-boot-erase-spi-rock64 image.

Write the erase-spi image to a SD card (which will erase the card):

xz -k -d -c -v -T 3 u-boot-erase-spi-rock64.img.xz | dd of=/dev/<sdcard> bs=1M

Insert the microSD card, wait for it to boot. You should see the power LED flash once per second. Then, remove the microSD card after about 30 seconds.
