[BPI-R2] Kernel Development

Strange I cannot see any kernel inside the tar.gz archive This is the folder content

It is only rootfs…i use my existing kernel (used for debian) but load rootfs of openwrt…

So I should unpack your 5.4 kernel from your github repo into the sdcard partition ?

I see OpenWRT has 5.4.28 as latest kernel but your repo has released 5.4.27 then 5.4.30

you can install my kernel on BPI-BOOT-partition and unpack tar.gz to another partition (in my case newly created 3rd partition), change uenv.txt (root to mmcblk0p3 and console to make ttyS0 first)

i guess you need to copy modules from debian to openwrt too, but this is only a quick test for building dual-boot function on existing image till openwrt can build a complete image

i have not found out how to select some packages without selecting them in menuconfig…i’m searching for a kind of defconfig for the selected arch/soc/board

I managed to boot using your latest 5.4.30 kernel and it almost completed but the i did not get to the CLI when connected to the serial port. I can type but do not see any shell prompt. Below is the boot log.

As i said above…you need to swap tty1 (hdmi) and ttyS0 (serial)

console=ttyS0,115200 console=tty1 fbcon=map:0

In your uEnv.txt (BPI-BOOT/bananapi/bpi-r2/linux/uEnv.txt

Have started work on 5.7…i used different vlan-patch than on 5.4 but seems to work well

https://github.com/frank-w/BPI-R2-4.14/tree/5.7-rc?files=1

Wifi/hdmi also ported, quick-tested and merged to rc-tree…

i have also replaced old vlan-patch in 5.4 with the new one because old one have problems on deleting vlans (all vlan are disabled)…have also ported vlan-patch to 4.19 to have vlan also working there

Hi Frank,

Sorry but I don’t understand the new build system (on the 5.7-rc kernel branch, I’m not very familiar with ARM boot too^).

With the old system, when I build my kernel, I could choose to generate deb packages and installed it on my board, on the next reboot, I was on the new kernel.

Now, I built my kernel, generated deb packages with pack_debs command (only 12M when old 5.5 and 5.4 was 50/60Mo ?) but when I installed them on board and reboot, i boot only on the old kernel. Deb package does’t install uImage on /boot/bananapi/bpi-r2/linux folder but vmlinuz and systemmap on /boot folder (like a classic linux).

Can I have the good procedure to install the new kernel ?

5.4 has additional patches for deb creation i have not yet merged…

just install directly to sd-card (option 2 in build.sh)

if you install debs you need to change uenv.txt to boot to new kernel

you can do also use pack-option… basicly there is for r2 only 1 uImage-file needs to be copied to BPI-BOOT-partititon (bananapi/bpi-r2/linux/) and modules-folder have to be copied to BPI-ROOT-partition (/lib/modules/) the tar.gz contains folders BPI-BOOT and BPI-ROOT…just unpack to the named partition on your SD…but install to SD-card is easier

Maybe it is right here, maybe it isn’t.

@frank-w Your Kernel README says, there is crypto support on 4.14. I just did a quick test.

Ensure you have algif_skcipher kernel module loaded.

Is the intention to compile it manually?

Cryptodev needs to be compiled separately,but is packed/installed if ko exists

Can anyone help me with the cfg80211 api-change for r2 internal wifi (mt6625)?

[BPI-R2] internal Wifi/BT (MT6625L) - Kernel

5.8-wifi and 5.8-hdmi are working in my quick test

It works, if kernel modules like described HERE are enabled.

Hi, everyone!

Today i got my R2 halted with 5.8 kernel for 1st time ever.

  1. Firstly network gone down (wifi, i didn’t test ethernet)
  2. I got dmesg dump using serial console: 5.8-dmesg.txt (72.9 КБ) (dump started from 1st trace after reboot, tha last one is incomplete)
  3. After reboot everything seems good for now, i cant reproduce the bug.

No 3rd party modules/drivers were used.

uptime 1 day and ~1 hr

seems like rcu-stall bug in mt76 wifi-driver, some before are warnings in clock/reset-driver caused by lima_clk_disable

i see you have 5.8.0-rc6, could you try with 5.8-main tree?

Sure, I’ll try to update it nearest weekend.

A couple of errors with self-reboot in 2 days 5.8-rc-fails.txt (23.1 КБ)

Now downgraded to 5.5, and 5.8-main compilation in progress…

P.S. Not actively used (as a PC ;)), not even logged in, just acted as a router (3-6 wifi clients both internal wifi and mt76), with serial console attached.

P.P.S BPI-MT7615 wifi card ( MT7612 wifi card replacement) is on the way, and as i understood it uses the same wifi driver as MT7612, is it correct?

Mt7615 uses also mt76 wifi driver right,but separate folder/CONFIG_option/module

I hope error is fixed in 5.8 final… maybe this: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/wireless/mediatek/mt76?h=linux-5.8.y&id=4ac668a3b8c9d3477a3fe162c1cfeb867dd65de8

else it will be interesting if error is in 5.7,5.6,… just to get the breaking commit

For lima i guess we need the power-commit i added to 5.4-main

I’ve switched to 5.8.0 release. I’ll update on any errors/stability issues.

Yep, or dts-mod from 4.4 kernel which is in my 5.5-lima branch, I’m not sure which way is better, but both seems to be working.
