Yocto BSP layer for FriendlyElec CM3588 NAS.

Based on upstream: https://git.yoctoproject.org/meta-rockchip

Configure Yocto/OE

In order to build an image, you need to download some layers:

~ $ mkdir yocto; cd yocto~/yocto $ git clone git://git.yoctoproject.org/poky -b scarthgap --depth 1~/yocto $ git clone git://git.yoctoproject.org/meta-arm -b scarthgap --depth 1~/yocto $ git clone git://git.openembedded.org/meta-openembedded.git -b scarthgap --depth 1~/yocto $ git clone https://github.com/JonLech/meta-cm3588-nas

Then you need to source the configuration script:

~/yocto $ source poky/oe-init-build-env

Finally, add layers to build/conf/bblayers.conf.

For example:

# build/conf/bblayers.confBBLAYERS ?= " 
  ${TOPDIR}/../meta-cm3588-nas 
  ${TOPDIR}/../meta-arm/meta-arm 
  ${TOPDIR}/../meta-arm/meta-arm-toolchain 
  ${TOPDIR}/../poky/meta 
  ${TOPDIR}/../poky/meta-poky 
  ${TOPDIR}/../poky/meta-yocto-bsp 
  ${TOPDIR}/../meta-openembedded/meta-oe 
  "

Building

~/yocto $ MACHINE=nanopc-nas bitbake core-image-full-cmdline

Build output directory: build/tmp/deploy/images/nanopc-nas

Flashing device (eMMC)

To flash the device you will need rkdeveloptool: https://github.com/rockchip-linux/rkdeveloptool

With power off and the USB-C on the CM3588 NAS connected to your Mac/PC, hold the mask button and connect power to the device.

Verify that the device appears in maskrom mode:

$ rkdeveloptool ld
DevNo=1	Vid=0x2207,Pid=0x350b,LocationID=802	Maskrom

Build the RK3588 loader:

git clone https://github.com/rockchip-linux/rkbin --depth 1
(cd rkbin; ./tools/boot_merger RKBOOT/RK3588MINIALL.ini)

Push the loader to the device:

$ rkdeveloptool db rkbin/rk3588_spl_loader_v1.16.113.bin
$ rkdeveloptool ul rkbin/rk3588_spl_loader_v1.16.113.bin

Flash the image to the device:

$ rkdeveloptool wl 0 core-image-full-cmdline-nanopc-nas.rootfs.wic

Reboot device:

$ rkdeveloptool rd
