Hi, everyone!

AFAIK openSUSE does not support Raspberry Pi 4 Model B yet. [1]

I’ve bought that board, I know the very basics on how to use it [2] and I want to help to port openSUSE to it. How can I start?

I'm working on some (still hacky) support for RPi4. You can find the JeOS image in my home project [1]. Beware that I was able to break the build of U-Boot yesterday. I'll try to fix this tonight.

I just gave that image a try and after a while staring at a console with no activity I noticed that it's the JeOS with jeos-firstboot, so I had to remove "console=tty" to actually see anything. Using the HDMI console won't really work without USB support. Also, chrony-wait should be disabled, it delays booting by 10min as no network is currently working. What doesn't work: - USB (expected), but the OTG port seems to be available. It's forced to host mode by the kernel though as gadget support is not enabled - WiFi: brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50 I see that you force-disabled WiFi stuff in JeOS.kiwi, I had to copy over the firmware manually - Ethernet: Gets detected just fine, but when actually sending packets the kernel freezes (sometimes with NETDEV WATCHDOG: eth0 (bcmgenet): transmit queue 1 timed out) - Sometimes the UART (clock?) glitches and there's garbled text What does work: - u-boot, grub, kernel, sd card, serial - I/O activity LED :D - cpufreq: Speed of "bc" corresponds roughly to CPU frequency So very nice progress already!

SLES doesn't support USB gadget mode AFAIK, so I didn't do anything there.

Hmm, looks like it should be changed, no?

SLE has CONFIG_USB_GADGET=n, so doing that would be a rather big change which needs discussion. It's not just a module which can be marked as unsupported. I don't know whether any platform currently supported by SLE even has USB device controllers. Cheers, Fabian Currently SLE has CONFIG_USB_GADGET=n. Cheers, Fabian

- Ethernet: Gets detected just fine, but when actually sending packets the kernel freezes (sometimes with NETDEV WATCHDOG: eth0 (bcmgenet): transmit queue 1 timed out) - Sometimes the UART (clock?) glitches and there's garbled text

Really? Did you change anything in the config.txt? I haven't experienced this up to now.

Nope. I see it occasionally after between grub and the login prompt. I can't 100% rule out a bad connection, but as it doesn't glitch out after logging in at all I think that's unlikely.

...

...

What does work: - u-boot, grub, kernel, sd card, serial - I/O activity LED :D - cpufreq: Speed of "bc" corresponds roughly to CPU frequency

So very nice progress already!

Thanks :)

...

I'll try to build a kernel with dwc2 peripheral support, maybe that's enough. Probably not though, considering it's USB-C...

That's not enough. Nicolas is working on some patches to enable PCI, which is needed by USB.

For the USB-A ports, yes. Also for USB-C which is connected to the dwc2 which the kernel already initializes properly?

My kernel-default wasn't picked up by OBS yet for the last three hours :-/

Success! It works fine with a USB-C -> USB-A cable. Run:

-CONFIG_USB_DWC2_HOST=y +# CONFIG_USB_DWC2_HOST is not set -# CONFIG_USB_DWC2_DUAL_ROLE is not set +CONFIG_USB_DWC2_DUAL_ROLE=y

modprobe libcomposite u_ether mount none -t configfs /mnt cd /mnt/usb_gadget mkdir g1 cd g1 mkdir configs/c.1 functions/eem.usb0 ln -s functions/eem.usb0 configs/c.1/ echo fe980000.usb > UDC

Forward a network connection, then:

echo "BOOTPROTO=dhcp" > /etc/sysconfig/network/ifcfg-usb0 ifup usb0

and you can ssh onto the pi4 and download stuff.

localhost:~ # hdparm -tT /dev/mmcblk1 /dev/mmcblk1: Timing cached reads: 1632 MB in 2.00 seconds = 816.32 MB/sec HDIO_DRIVE_CMD(identify) failed: Invalid argument Timing buffered disk reads: 126 MB in 3.01 seconds = 41.90 MB/sec

I played around with some other programs and it seems like CPU performance has roughly doubled compared to a 3B+.

A72 vs A53. 😉 You may also have CPUFreq which boost perfs, if you are running a 5.3+ kernel. Cheers, Guillaume

Even over X11 forwarding applications run very smoothly.

On my wish list is now to have u-boot use the device tree from the firmware for its own initialization as well, so that hardcoding of addresses isn't necessary anymore. That way we wouldn't need a new u-boot-rpi4 flavor and new JeOS flavors installing it instead of u-boot-rpi3.

Hi, folks! I know how to use OBS and KIWI, but when it comes to compile kernels, I'm a complete noob... also, I'm getting started with Raspberry Pi. I thought that would be easier, as there are at least three Linux distributions now (Raspbian [1], LibreELEC and Manjaro) supporting Raspberry Pi 4. Isn't there a kind of copy/paste that could allow us to boot openSUSE reusing Raspbian configs, for instance? What I've done so far... I downloaded Matthias' image: openSUSE-Tumbleweed-JeOS.aarch64-15.1.0-RaspberryPi4-Build61.1.raw.xz (did I choose the right one?) and flashed into the SD card using balenaEtcher [2]. During boot, I saw something like GRUB (did you say U-Boot?). My RPi4 is connected to a HDMI monitor, which worked, but USB keyboard did not respond and I got only this: https://paste.opensuse.org/42439427 Am I doing something wrong?

What do you mean by Rasbian configs? Do you mean the kernel config? We are trying to support RPi4 with the mainline kernel. Raspbian uses a downstream kernel which only works on RPis, so the kernel config won't work on our mainline kernel.

Yes, that's what I meant: kernel config :) I thought about, using openSUSE tools, build a kernel close to the Raspbian's one. Maybe that's what Manjaro did. Now I have 3 SD cards with Raspbian, Manjaro and openSUSE (your in development port). Talking about kernel versions... openSUSE Leap 15.1 for x86-64 - 4.12.14 (I use it on my laptop) Manjaro ARM 19.08 with XFCE - 4.19.65 * Raspbian Buster (10.0) - 4.19.66 * see they are close? Your latest build - 5.3.rc8 (according to openSUSE-Tumbleweed-JeOS ... .packages) openSUSE Tumbleweed for x86-64 - 5.3.1 (according to software.opensuse.org) In kernel.org: stable - 5.3.2 longterm - 4.19.76 I think I'm going to follow your work, but in parallel I will try to port openSUSE Leap 15.1 to RPi4 using an older kernel (4.19.x). Or maybe I will work on 15.2, it seems people are already working on it. I've got a lot to study: how to build ARM packages with OBS, how to compile kernels, how to build OEM images with KIWI / OBS (I'm used to build live ISOs)...

Also, I was able to build something at OBS: https://build.opensuse.org/package/show/home:kamarada:15.1:dev:RPi4/raspberr... But OBS built it for x86_64, while armv7l and aarch64 were excluded.

Why are you doing this?

Although I agree the best way is what you are doing (trying to integrate the RPi4 modules into the upstream Linux kernel), I believe the fastest way of getting a working Leap 15.1 on a RPi4 is to use the same kernel provided by the Raspberry Pi Foundation and already used by Raspbian and Manjaro. So, I decided to try that other direction.

You need to change the the project's meta and add a repository for arm. This should give you the idea: https://build.opensuse.org/projects/hardware:boot/meta

Keyboard and mouse will need to get connected to the USB3.0 port, or are you able to connect and power the deivce via the type-C connector?

Yes. I power the device via the USB-C with a 5V 3A unit with a converter cable.

OK. I am patiently waiting. Indeed the message Chester Lin mentioned is found in the journal. But I do not have the skills to do anything with his suggestion. I even have a problem with screen to connect via my USB serial line to the RPi4. I can't find how to change the window size from 24x80 to something larger. I tried "C-a : width -w 132 48" and "C-a : displays" these values, but my lines are cut off at 80.

Hi,

I'm working on some (still hacky) support for RPi4. You can find the JeOS image in my home project [1]. Beware that I was able to break the build of U-Boot yesterday. I'll try to fix this tonight.

Regards, Matthias

I am still unable to get any output on an attached HDMI monitor. Also using Raspbian Buster is not showing anything on the screen.

If you don't see any output with Raspbian than this hints to a problem with your HW setup. Check the cable/monitor etc. Regards, Matthias

This last system has a application, tvservice, to manipulate the output to the screen. It shows HDMI0 is active.

Is there something in openSUSE which does the same?
