[BPI-R64] Kernel-Development

Ilya_Murav_jov · February 2, 2020, 9:58am

After some poking I got compatible linux-headers, I think:

$ bash build.sh build
...
$ cat include/config/kernel.release
5.4.0-bpi-r64-r64-main

$ LOCALVERSION=-r64-main ./scripts/setlocalversion .
-bpi-r64-r64-main

$ LOCALVERSION=-r64-main ARCH=arm64 CROSS_COMPILE='ccache aarch64-linux-gnu-' make bindeb-pkg

$ ls -lah ../*.deb

imho it works, e.g. https://linux-sunxi.org/Mainline_Kernel_Howto#Specific_Debian_kernel_notes

Then, to make the kernel, use; substituting your cross compiler;:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- deb-pkg

Note: if you want to build, but not start from scratch, the target bindeb-pkg does not do a clean first, whereas deb-pkg does.

I’ll later try to adapt to banana pi reality.

“works” is relative it does not create an uImage and path for kernel-image is not the one used by bpi-images (/boot/bananapi/bpi-r*/linux/).

for r2 you need 32bit uImage/kernel with appended dtb
for r64 you need 32bit uImage with 64bit kernel and with dtb in dtb-folder

if we solve this we can use

ARCH=arm CROSS_COMPILE='ccache arm-linux-gnueabihf-' LOCALVERSION=-main make bindeb-pkg #r2
ARCH=arm64 CROSS_COMPILE='ccache aarch64-linux-gnu-' LOCALVERSION=-r64-main make bindeb-pkg #r64

after importconfig

but for linux-headers i can add it to build.sh/travis, if i found out how to build/upload only the headers-deb

scripts/Makefile.package:

KBUILD_PKG_ROOTCMD ?="fakeroot -u"

deb-pkg:
        $(MAKE) clean
        $(CONFIG_SHELL) $(srctree)/scripts/package/mkdebian
        $(call cmd,src_tar,$(KDEB_SOURCENAME))
        origversion=$$(dpkg-parsechangelog -SVersion |sed 's/-[^-]*$$//');\
                mv $(KDEB_SOURCENAME).tar.gz ../$(KDEB_SOURCENAME)_$${origversion}.orig.tar.gz
        +dpkg-buildpackage -r$(KBUILD_PKG_ROOTCMD) -a$$(cat debian/arch) $(DPKG_FLAGS) -i.git -us -uc

bindeb-pkg:
        $(CONFIG_SHELL) $(srctree)/scripts/package/mkdebian
        +dpkg-buildpackage -r$(KBUILD_PKG_ROOTCMD) -a$$(cat debian/arch) $(DPKG_FLAGS) -b -nc -uc

maybe we can set KBUILD_PKG_ROOTCMD or DPKG_FLAGS to create source-only or using script before to generate uImage…DPKG_FLAGS seem not to be set anywhere

btw. bindeb-pkg should build only binary package (not source), see help at the end of makefile…but in my test it also creates the source-deb, but deb-pkg makes clean before and seem to create a source tarball. filename ($kernel_headers_packagename) for source-deb is set in the mkdebian script, but i have not found where it was used to create the headers-file…i guess somewhere with the debian/control file, where also the others are listed.

some of the magic (including collecting files for headers-package) seems to be in this script: scripts/package/builddeb

imho adding mkimage and patchs for dtb should be added here. there is also a section about location for image…there is no arm/arm64-part…maybe we can add one using an ENV-Variable to set target-directory

diff --git a/scripts/package/builddeb b/scripts/package/builddeb
index c4c580f547ef..5ca7d49e1227 100755

 esac

but we need to build uImage before…but how

the build itself seems to be done in same file

cp "$($MAKE -s -f $srctree/Makefile image_name)" "$tmpdir/$installed_image_path"

we could call dtbs/mkimage after it or passing all options to the existing make

maybe it’s easier to unpack the deb after generation, remove the wrong vmlinux and adding missing files

Ilya_Murav_jov · February 5, 2020, 2:33pm

@frank-w I’ve changed builddeb a little, so one may build linux-image, linux-headers and linux-libc-dev like so

bash build.sh importconfig
bash build.sh build
bash build.sh cryptodev
bash build.sh pack
bash build.sh pack_debs
ls ../*.deb
../linux-headers-5.4.17-bpi-r64-main-packaged_5.4.17-bpi-r64-main-packaged-1_arm64.deb  ../linux-libc-dev_5.4.17-bpi-r64-main-packaged-1_arm64.deb
../linux-image-5.4.17-bpi-r64-main-packaged_5.4.17-bpi-r64-main-packaged-1_arm64.deb
...

I think it is a good idea add the command to https://github.com/frank-w/BPI-R2-4.14/releases

Meanwhile, I’ve tried the last commit 2e4b86dfcf329f94ac123175b3eed5231b77bbf6 for my BPI-R64 and it doesn’t work for me because DHCP/WAN=eth1 doesn’t work:

Was in 5.4-r64-main:

Any clues?

In 5.4-main i merged dsa driver for r64 and did not merged openwrt phy driver for r64.

You can now work with wan instead of eth1,but need to set eth0 up before…config like for r2. Have you tried working on wan?

Eth is defined in dts only for soc-side (thats why it is visible in ip a),but switchside (port5) is not defined

		phy-mode = "rgmii";


		fixed-link {

	};

Just try wan/lanX instead of ethX

For internal wifi…i see a semaphore error on boot,but if i unload module and load again it works in my quick tests…have not found cause of it…[BPI-R64] mt7622 mac80211 WiFi driver

@Ilya_Murav_jov

i have applied your patches to new branch 5.4-deb with changes for r2 (using uImage instead of uImage_nodt). have not tested much due to less time

Ok, wan works. About lanX, I couldn’t use them with dnsmasq to connect clients to the BPI, do you mean it is not ready now? My configs is:

Earlier I used eth0 in dnsmasq’ config and that worked, now I tried lanX instead and failed.

About internal Wifi, yes sometimes reloading works, but in most cases not

The tag: looks wrong

Here is my config for r2…should work for r64 too

http://fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:network:start#dhcp

Have you set them up via interfaces/manual? For dhcp you should set fixed ip to lanport and run dnsmasq on this interface with same subnet and extending range

For wifi…if i understand you right it sounds like timing issue…maybe we can fix it with a delay before semaphore/firmware-load

Hi,

My R64 after some time of working (1-2 days) throws the following, and after that I cannot use ethernet till I restart the system:

The kernel is 5.4 from @frank-w repo,

What does this error mean?

Hmm, something wrong with

Afair 5.4 has no second gmac support…so no eth1.

Could you try if network is broken on 5.6-main? I have 3 patches merged that were missing while phylink conversion

Ilya_Murav_jov · April 10, 2020, 8:13pm

Thanks, I’ll try.

By the way, what is gmac and why one doesn’t suffice?

frank-w · April 11, 2020, 6:54am

Gmac is the ethernet-lane between soc and switch. There are 2,but gmac #0 on r64 works in sgmii-mode (2.5gbit/s) where the other supports only rgmii (1gbit/s). On r64 basicly 1 is enough for common uses…currently dsa-framework does not support more than 1. So i wonder why your output shows 2…i guess you use the older openwrt driver i had in my repo till 5.4 was released. This had not used dsa-framework and hardwired lan-ports to eth0 and wan to eth1

Ilya_Murav_jov · April 11, 2020, 7:55am

No, I don’t ~~use~~ touch eth1 myself

I’ll check it again.

frank-w · April 11, 2020, 7:57am

Can you show uname -r? That should be 5.4-rcx

Ilya_Murav_jov · April 11, 2020, 7:57am

root@bananapir64:~# uname -r
5.4.24-bpi-r64-main

Most likely the kernel is from https://github.com/frank-w/BPI-R2-4.14/releases

frank-w · April 11, 2020, 9:29am

mhm, ok, i see in r64 dts that second gmac is defined but not defined on switch-side (port 5), so it appears in “ip a” but it’s not usable

I am using 5.6-main now, it is ok (now, without wifi=mt7622.ko).

frank-w · April 11, 2020, 12:18pm

right, have not merged mt7622 wifi-driver to this tree due to missing freetime, but your watchdog-warning/crash was in ethernet-driver ( mtk_soc_eth)

if it is working you can try adding these 2 Patches to 5.4:

05f57ab128ce net: ethernet: mediatek: move mt7623 settings out off the mt7530
903987b837eb net: dsa: mt7530: move mt7623 settings out off the mt7530

currently try to add mt7622, changed Kconfig/Makefile to new folder containing driver, but still old folder is used

edit: have found the problem…mt76_new/Kconfig still referred the Kconfig in mt76/* have fixed it and do a test-build and then upload. btw. have added the 2 Patches from rene in 5.4-main

Ilya_Murav_jov · April 12, 2020, 11:54am

You mean 5.6 I think… Ok, but i’ll wait one more day or two to see if it is working more stable than 5.4
