Installation on Cubietruck Plus

Postby DocBoolean » Tue Jul 03, 2018 8:22 am

Dear Community,

I know the Cubietruck Plus isn't supported right now, but I want to contribute to change that. I've been testing multiple distributions in the past days and already got fedora server and centos running on this device...now I want more...I want Arch Linux Arm! :)

I've cross compiled the latest u-boot for CT Plus, downloaded the latest armv7 build (ArchLinuxARM-armv7-latest), written both to sdcard, but - of course - the boot parameters are missing and that's what I wanted to ask you. How can I adjust settings for root partition and /boot ?

My sdcard layout is: one ext4 partition (mmcblk0p1) with u-boot dd-ed to mmcblk0 (bs=1024 seek=8).

U-boot starts, but due to missing configuration doesn't load the arch kernel.

I think it should be pretty similar to the Cubietruck config, but I don't know how to generate the config from source.

Please help :)

You'll need to look into the uboot source - to see how it is configured for the cubietruck. Different machines have it set up differently.

1) Beagle familly uboot reads the eeprom to get the machine and loads a device tree for the device
2) many machines look for /boot/boot.src and run that
3) some machine read /boot/uEnv.txt
4) many machine read the uboot enviromental varibales, that are saver to the HDD, in an area uboot owns

So you need to understand what your uboot expects - and then set that up correctly.

So from what I can see on: https://github.com/u-boot/u-boot/blob/master/configs/Cubietruck_plus_defconfig its a sunxi style set up.

I'g guess that this uses the include file https://github.com/u-boot/u-boot/blob/master/include/configs/sunxi-common.h.

That says that it expects the 1st partition on the mmc to be the /boot partition, to be ext2 formatted, and to contain uEnv.txt (used to set up whatever parameters you need) and to boot uImage (so that needs creating).

So this suggests it is old style.

Dear summers,

thank you for these information, according to the CT Plus u-boot, kernel loadaddr is 0x40007800, the settings for uEnv.txt are explained in the sun8iw6p1.h file; I've set up my sdcard using a boot partition starting at 8192 (1024*8 <-u-boot-dd-params seek=8) with 30M size, formatted ext2 and a / partition formatted ext4. I'm currently cross-compiling kernel 4.17.2, hopefully everything will be working, I'll report back as soon as I've tested. :)

EDIT: The system still is not booting, I'm afraid. On my boot partition I have uImage, boot.cmd and uEnv.txt, the partition is marked bootable via fdisk.

Contens of boot.cmd:
Code: Select all
setenv bootargs console=ttyS0,115200  console1=tty0 root=/dev/mmcblk0p2 rootwait panic=10
load mmc 0:1 0x40007800 uImage || load mmc 0:1 0x40007800 boot/uImage
bootm 0x40007800


This is according to the sunxi u-boot mainline configuration

Contents of uEnv.txt:
Code: Select all
bootdelay=3\0
bootcmd=run setargs_mmc boot_normal\0
console=ttyS0,115200\0
console1=tty0\0
mmc_root=/dev/mmcblk0p2\0
loglevel=8\0
setargs_mmc=setenv bootargs console=${console1} console=${console} root=${mmc_root}
loglevel=${loglevel}\0
boot_normal=fatload mmc 0 40007800 uImage;bootm 40007800\0


CAVE: Doesn't fatload mean that the boot partition has to be FAT and not ext2 ? (I'll try with ext2load) -> didn't work
->created FAT partition and fs using fatload -> didn't work either

This is according to the sun8iw6p1.h

What can I do to resolve this issue ?

EDIT: I created a boot.cmd file containing:
Code: Select all
fatload mmc 0 0x46000000 uImage
fatload mmc 0 0x49000000 sun8i-a83t-cubietruck-plus.dtb
setenv bootargs console=tty0 earlyprintk root=/dev/mmcblk0p2 rootwait panic=10 ${extra}
bootm 0x46000000 - 0x49000000


and created the boot.scr via (sunxi-tools):
Code: Select all
mkimage -C none -A arm -T script -d boot.cmd boot.scr


Copying the boot.scr file to my boot partition, the kernel starts to load, but stops at this point:

EDIT -> -> EDIT:

I finally got it working, not with my compiled custom kernel, but with the one provided in the package. :)
It took a little work, but this is what I did:

- I copied /boot/zImage to my boot partition
- I adapted my boot.cmd :

Code: Select all
fatload mmc 0 0x46000000 zImage
fatload mmc 0 0x49000000 sun8i-a83t-cubietruck-plus.dtb
setenv bootargs console=ttyS0,115200 console1=tty0 earlyprintk root=/dev/mmcblk0p2 rootwait panic=5 ${extra}
bootz 0x46000000 - 0x49000000


- created the new boot.scr (see above), copied it to my boot partition

Then I inserted the microSDcard into my CT Plus, pressed power button and everything booted just fine.

I think I will create a short howto ouf of this, because now as I have gone through all of this, it seems pretty easy. :)

That would be fantastic! Thanks in advance.
