Any plan for basic mainline linux support?

[gneville]

So I built from miskol's Armbian fork but it resulted in the device not being able to boot, nothing appeared on the screen via HDMI.

Code: Select all

git clone https://github.com/xlazom00/build.git -b odroidn2-linux-5-13
git branch
./compile.sh
sudo BETA=yes EXPERT=yes ./compile.sh

Which gave me:

Code: Select all

Armbian_5.88.190614_Odroidn2_Ubuntu_bionic_dev_5.1.0.img

sudo BETA=yes EXPERT=yes BOARD=odroidn2 BRANCH=dev RELEASE=bionic BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no ./compile.sh
booting fine
you should build development kernel
https://github.com/xlazom00/build/blob/ ... 2.conf#L32

That's pretty much what the summary out showed my build options were for doing a repeat build. I ran ./compile and I wanted to change the kernel config as I needed some modules for kubernetes. If I wanted to run your CLI command which .config file should I edit to manually add the modules I want to build first (ie. What's the location of the .config file that the script uses to build from for an odroid n2?) It looks like it's https://github.com/xlazom00/build/blob/ ... dev.config

Thanks

sorry I got it
git clone https://github.com/xlazom00/build.git -b odroidn2-linux-5-13

touch .ignore_changes # this is important!!!
sudo BETA=yes EXPERT=yes BOARD=odroidn2 BRANCH=dev RELEASE=bionic BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no ./compile.sh



armbian will switch to git master
but when you create file .ignore_changes, it will ignore all changes/branches
soooooooorrrrrrrryyyyy

[gneville]

Thanks miskol, Creating the .ignore_changes file now produces an image name of Armbian_5.88.190615_Odroidn2_Ubuntu_bionic_dev_5.2.0-rc2.img

This now successfully boots! However I've still got the same network issues as before where the NIC isn't picking up a DHCP address. It still doesn't work with a static IP.

Build steps:

Code: Select all

git clone https://github.com/xlazom00/build.git -b odroidn2-linux-5-13

git checkout odroidn2-linux-5-13
sudo BETA=yes EXPERT=yes BOARD=odroidn2 BRANCH=dev RELEASE=bionic BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no ./compile.sh

Select "Full OS image for flashing"
Select "Show a kernel configuration menu before compilation"

Set the following options for kubernetes:

Code: Select all

General Setup > Control Group Support > PIDs controller - Should have a star already
Networking support > Networking Options > Network packet filtering framework (Netfilter) > IP set support - Set to star 
Networking support > Networking Options > Network packet filtering framework (Netfilter) > Core Netfilter Configuration > Netfilter Xtables support (required for ip_tables) - set to star
Networking support > Networking Options > Network packet filtering framework (Netfilter) > Core Netfilter Configuration > set target and match support - Set to star

Save as .config and exit

I don't have any problem with NIC
but I didn't change anything in kernel config. kernel config is same as for Ondroid C2 with N2 hw enabled

[gneville]

I did try a build with no modifications but still networking doesn't work.

[gneville]

I've managed to get networking working by hard coding speed and duplex to 100M, if I try 1G it fails to work, Very odd!

Code: Select all

ethtool -s eth0 speed 100 duplex full autoneg off

Anyone else successfully running at 1G full duplex?

[mad_ady]

If you're not using Hardkernel's stock uboot, there's a patch to increase tx voltage, without witch some boards have problems at gigabit. I don't have the patch offhand, but it's a one-line change in u-boot.

[elatllat]

https://github.com/hardkernel/u-boot/co ... b29f835b98

Maybe?

[mad_ady]

Yes, that one, thanks!

[back2future]

Compilation environment doesn't accept default ntfs filesystem, because of wrong directory permissions.
[ dpkg-deb: error: control directory has bad permissions ]
Just in case somebody starts downloads and compilation attempt on ntfs (12.6 GiB disk usage til that point): copy build folder to ext4 fs and restart compiling, works (xz standard compresses 15.9GiB to 3.5GiB)
[ while ntfs is a posix compatible filesystem, learned, that (re)mounting with UUID=partitionsUUID /mountable_directory ntfs-3g auto,users,permissions 0 0 (e.g. fstab line) can be another possibility enabling chmod/chown, but have not tried yet. ]

armbian and my fork use hardkernel's u-boot so that patch is there

I'm on 1GBit ethernet but my switch is like 50cm from board

My 5.2 crypto (xts) speed is about half of 4.9. anyone know a config or commit that might help?

[balbes150]

My 5.2 crypto (xts) speed is about half of 4.9. anyone know a config or commit that might help?

The main kernel is only running all core at 1.2 (not 1.8\1.9), so the performance will be lower.

cpufreq-info said "no or unknown cpufreq driver is active on this CPU"
This dts commit looks relevant, not sure how to translate that to upstream.

Hello elatllat,

woof! Thank you!
I will try it!

Best regards, johno

[maier-johno]

hm, the script doesn't work. Is there an explanation for the script?

I would like to do it manually so I understand what is important. But thanks anyway!

[elatllat]

...doesn't work...

hard to help with so little information. (bash -x script)

...explanation...?

just read the man page of any command you don't understand.

... when the kernel is ready for users that don't understand some basics there will be an easy installation method.

[Nuems]

...doesn't work...

hard to help with so little information. (bash -x script)

There are four "if"s but just three "fi"s. Just saying.

[elatllat]

..."if"s...

Thanks, I fixed that copy paste fail.

[maier-johno]

Thanks guys for the help! I will try it again soon (when I have a backup). I'm not sure because i'm booting from a USB harddisk. If the script works, then it's really fantastic!

Still, I want to understand what it does exactly and how it works. I'm new and things like "UBOOT" etc. doesn't tell me much....

it now possible to use the current kernel 5.2?
Only if you apply some patches aimed at 5.3

Does this mean that the N2 might be able to run 5.3 without user hacks?

[Rising_Sun]

Hey,

I used elatllat script, had to change linux to linux-amlogic at "if [ ! -d "$F/linux" ] ; then" and "cd linux". #Not needed anymore with the updated script
It compiled and rebooted succesfully but the device outputs only a black screen and network does not come up.

[aplund]

I'm still struggling with this. Using the linux-amlogic branch of khilman referred to by elatllat above, I get the below output and nothing further.

It's the "FDT_ERR_NOTFOUND" and "[rsvmem] fdt get prop fail." that make me wonder.

The dts got merged into next,

I'll check again at 5.3-rc1 for a 100% mainline boot,
back to the patched 5.2 for now.

I haven't been using the N2 for a while and this all all from memory but the FDT_ERR_NOTFOUND / rsvmem I remember is nothing to worry about it just means that uboot cannot read / modify the dtb file (different format in mainline) and can be ignored as we don't really need to modify it within uboot environment. its still loaded and passed onto the kernel

In regards to waiting "Waiting for root device /dev/mmcblk1p2" a couple of things

- this is waiting for an sdcard. Are you using sd card or mmc? For emmc you need to specific root=/dev/mmcblk0p2 instead
- As you are not running a ramdisk we need to have all the emmc / sd drivers built into to kernel as we can not load modules until the disk is mounted. I think this is the main one
CONFIG_MMC_MESON_GX=y
- We need to have "rootwait" option set also in the boot for some cards to tell the kernel to wait for a bit until driver has initialised or we see the message you received
- If you are booting an image like armbian with no fat partition then you might need to modify the partition being used as there is only 1 ext partition. root would like something like /dev/mmcblk0p1

As an example my bootargs for hardkernel ubuntu are (This is emmc with rootwait set)...

setenv bootargs "console=ttyAML0,115200 root=/dev/mmcblk0p2 rw rootwait"

As a side note, emmc / sd numbers in uboot / mmc are swapped. mmc 1 (eg fatload 1:1) is emmc card but in linux it is 0 eg mmcblk0, sd is 0 in uboot but 1 in kernel

[aplund]

The dts got merged into next,
but boot stops at the rtc.
I'll check again at 5.3-rc1 for a 100% mainline boot,
back to the patched 5.2 for now.

I'm running into this now that I have a working kernel output. This can be bypassed by adding 'clk_ignore_unused' into your cmdline. There must be something missing from the dtb.

[sbi]

I also managed to get to this point where the boot stopps at the rtc.

This can be bypassed by adding 'clk_ignore_unused' into your cmdline. There must be something missing from the dtb.

With clk_ignore_unused, the boot continues and later when my root fs is setup I get

I must have overlooked the config adaptations in your script . Mine was with bare defconfig + btrfs enabled. I will give it a try (also with the next branch).

Had to put make olddefconfig into your new script.

Now its compiling. Testing soon.

Its booting fine and network is up too.

[aplund]

Has anyone with the ethernet problem tried the amlogic/v5.3/dt64 branch from git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git?

There seems to have been some issue with the ethernet reset line and the device trees were changed very recently to address the issue.

Have you checked if you have included the voltage regulator drivers? Even though most of them a "fixed", drivers won't probe if you don't include the regulator drivers.

I think 0x70000000 (0x80000000-0x10000000) would be more safe in the script because there are devices with 2GB. Maybe a switch?

I changed the value to 0xefd00000 for testing. (4GB-256MB-3MB)
Made more sense for me because in meson-g12a.dtsi the reserved memory is 256MB+3MB.
Is this unnecessary? Does secmon use the memory of cma anyway? I dont see any differences other than loss of 3MB memory.
