Boot.scr problems on Orange Pi PC

exoid · Published in 2016-10-8 02:25:40

Hello everyone,
at the moment i am working on my Orange Pi PC. To compile mainline kernel + uboot(using latest linaro toolchain) is not a problem for me even not to write the bootloader. But i have a big problem to write the boot.scr for my zImage on a two partition sd card (16mb fat for kernel and dtb + rest ext4 for rootfs). I can nowhere find a working boot.cmd for my configuration and there is no proper documentation to write it for my self. To bring it to the point: Could someone help me create a working boot.scr?
Here are the contents of my scripts to build kernel + uboot + writing sd card (ill spare you the content of my boot.cmd because i triend near 20 variations) :

Script to build uboot + mainline kernel:

#!/bin/sh
masterfolder=/builder
finalfolder=/final
mountdir=/mnt/rootfs
export ARCH=arm
export PATH="$PATH":$masterfolder/toolchain/bin/
export CROSS_COMPILE=arm-linux-gnueabihf-
mkdir $finalfolder
##GettingUboot##
cd $masterfolder
git clone git://git.denx.de/u-boot.git mainline-uboot

#make CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make CROSS_COMPILE=arm-linux-gnueabihf-
cp $masterfolder/mainline-uboot/u-boot-sunxi-with-spl.bin $finalfolder/u-boot-sunxi-with-spl.bin
rm -rf $masterfolder/mainline-uboot
##Build Mainline Kernel##
mkdir $finalfolder/output
cd $masterfolder
cp -r mainline-kernel kernelwork
cd kernelwork

#make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage dtbs modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=$finalfolder/output modules_install
cp $masterfolder/kernelwork/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dtb $finalfolder/sun8i-h3-orangepi-pc.dtb
cp $masterfolder/kernelwork/arch/arm/boot/zImage $finalfolder/zImage
cd $masterfolder
#rm -rf kernelwork

After a longer searh ifound the "mainline uboot" site in the sunxi wiki. The boot.cmd works for me with one and two partitions. If someody have the same problem just write.

The kernel will be loaded from the FAT partition, and the Mini Crossword root file system will be mounted from the ext4 partition.
