[opensuse-arm] (Untested) RPI3 image - testers wanted
Hi, http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Rasp... (yeah, I know its the Pi2 path, I was lazy) contains an untested raspberrypi3 image. I already know that serial is broken, that seems to be an upstream issue (due to the changed clock frequencies). I haven't tested it further yet, need to buy some HDMI capable screen first. Let me know your findings. Greetings, Dirk -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

I have a patched u-boot version that can use for serial output if you like. In a nutshell, the downstream kernel crashes when used with device tree. Without device tree, it boots successfully (with start.elf). With device tree, it crashes the same way on both start.elf and loaded via u-boot. Below is a kernel log dump. I can't really make sense of it yet. There's probably code missing to deal with failed allocations. But I don't see why there would be any at that early stage of the boot.

I have a patched u-boot version that can use for serial output if you like. In a nutshell, the downstream kernel crashes when used with device tree.
Without device tree, it boots successfully (with start.elf). With device tree, it crashes the same way on both start.elf and loaded via u-boot.
Below is a kernel log dump. I can't really make sense of it yet. There's probably code missing to deal with failed allocations. But I don't see why there would be any at that early stage of the boot.
The current staging image works :). Yay! Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

I have successfully installed this image: http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Rasp... It has several issues with booting. Uboot issues messages for a while and eventually comes to a prompt. If I type "boot", it boots up. At some point I noticed in dmesg a complaint that the first partition was "dirty" and needed an fsck. It is a FAT filesystem and fsck.fat isn't installed. I installed "dosfstools" and checked the file system. One of the uboot messages complained that "usbethaddr" was not set.

Variable "scan_dev_for_efi" is a script that tries to set variable "boot_prefixes" but doesn't get it right. I will read u-boot documentation and try to figure it out but if somebody fixes it I can move on to something else. Thanks.

I don't think we support the usb mac stuff quite yet. If you have great ideas how to make it work with upstream U-Boot, we're more than happy to see patches :).

The way it works without U-Boot is that the RPi bootloader generates the mac address from the pi serial number. We should probably do the same in U-Boot. IIRC it then gets passed to the kernel using the kernel command line. That's a horrible interface, as it breaks any integration with boot loaders (like grub2). So if we want to move this to an efi based boot mechanism, we need to instead inject the mac address into the device tree. I'm not quite sure where though - usb is not described in dt.
There are also messages about variables "bootfile" and "pxeuuid" being missing. Variable "scan_dev_for_efi" is a script that tries to set variable "boot_prefixes" but doesn't get it right.
That's the bug that was fixed in u-boot and stuck in review. Basically the bootfile definition got included in the scan_dev_for_efi variable while it should've been its own variable. I simply forgot the null terminator.
I will read u-boot documentation and try to figure it out but if somebody fixes it I can move on to something else.
That leaves the mac address thing to fix :). Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

The MAC address seems to be RPI's prefix b8:27:eb plus the last 3 bytes of the serial.
This big problem is not how to fetch the 3 bytes. It's how to pass them all the way from u-boot via fdt to the kernel and have the kernel properly use it as the mac address for the usb ethernet adapter.

(yeah, I know its the Pi2 path, I was lazy) contains an untested raspberrypi3 image. I already know that serial is broken, that seems to be an upstream issue (due to the changed clock frequencies).
I haven't tested it further yet, need to buy some HDMI capable screen first. Let me know your findings.
Greetings, Dirk I have successfully installed this image:
http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Rasp...
It has several issues with booting. Uboot issues messages for a while and eventually comes to a prompt. If I type "boot", it boots up. At This is my fault again - as soon as the image got rebuilt with the fixed U-Boot package (that was stuck in Factory review for a week) this error should be gone.
some point I noticed in dmesg a complaint that the first partition was "dirty" and needed an fsck. It is a FAT filesystem and fsck.fat isn't That's weird. Sounds like a flushing bug during build?
installed. I installed "dosfstools" and checked the file system.
One of the uboot messages complained that "usbethaddr" was not set. I don't think we support the usb mac stuff quite yet. If you have great ideas how to make it work with upstream U-Boot, we're more than happy to see patches :).
Every time it boots it chooses a new MAC address which causes the dhcp server to give it a new address every time. I set that variable and did a saveenv. I suppose that is supposed to happen somehow during the first boot. The way it works without U-Boot is that the RPi bootloader generates the mac address from the pi serial number. We should probably do the same in U-Boot.
IIRC it then gets passed to the kernel using the kernel command line. That's a horrible interface, as it breaks any integration with boot loaders (like grub2). So if we want to move this to an efi based boot mechanism, we need to instead inject the mac address into the device tree. I'm not quite sure where though - usb is not described in dt.
There are also messages about variables "bootfile" and "pxeuuid" being missing. Variable "scan_dev_for_efi" is a script that tries to set variable "boot_prefixes" but doesn't get it right. That's the bug that was fixed in u-boot and stuck in review. Basically the bootfile definition got included in the scan_dev_for_efi variable while it should've been its own variable. I simply forgot the null terminator.
I will read u-boot documentation and try to figure it out but if somebody fixes it I can move on to something else. That leaves the mac address thing to fix :).

The MAC address seems to be RPI's prefix b8:27:eb plus the last 3 bytes of the serial. This big problem is not how to fetch the 3 bytes. It's how to pass them all the way from u-boot via fdt to the kernel and have the kernel

I think it passes ethaddr, not usbethaddr. So, you may want to also set ethaddr. Guillaume

The MAC address seems to be RPI's prefix b8:27:eb plus the last 3 bytes of the serial. This big problem is not how to fetch the 3 bytes. It's how to pass them all the way from u-boot via fdt to the kernel and have the kernel

In the version of boot.script (and boot.scr) that I have there is this long statement to set boot args to pass to the kernel. The MAC address for the ethernet adapter is set via "smsc95xx.macaddr" setenv bootargs "root=/dev/disk/by-id/mmc-SE32G_0xa82b1160-part3 loader=uboot disk=/dev/disk/by-id/mmc-SE32G_0xa82b1160 resume=/dev/disk/by-id/mmc-SE32G_0xa82b1160-part4 quiet splash=silen t plymouth.enable=0 dwc_otg.lpm_enable=0 console=ttyAMA0,115200n8 kgdboc=ttyAMA0,115200 rootflags=commit=120,data=writeback smsc95xx.macaddr=${usbethaddr} ${append}" I then set "usbethaddr" as an environment variable and it works nicely. I just used the last random address but I can set the right one that way.

This big problem is not how to fetch the 3 bytes. It's how to pass them all the way from u-boot via fdt to the kernel and have the kernel properly use it as the mac address for the usb ethernet adapter. You may ask on u-boot mailing list. I think u-boot is able to do it more or less automatically. Have a look at fdt_fixup_ethernet(...) function. That only works for devices listed in device tree though, right? The eth adapter is attached to USB which doesn't list its devices in dt.
Yes, I think so. Ask on u-boot ML, maybe people would have some idea.

In the version of boot.script (and boot.scr) that I have there is this long statement to set boot args to pass to the kernel. The MAC address for the ethernet adapter is set via "smsc95xx.macaddr"
setenv bootargs "root=/dev/disk/by-id/mmc-SE32G_0xa82b1160-part3 loader=uboot disk=/dev/disk/by-id/mmc-SE32G_0xa82b1160 resume=/dev/disk/by-id/mmc-SE32G_0xa82b1160-part4 quiet splash=silen t plymouth.enable=0 dwc_otg.lpm_enable=0 console=ttyAMA0,115200n8 kgdboc=ttyAMA0,115200 rootflags=commit=120,data=writeback smsc95xx.macaddr=${usbethaddr} ${append}"
I then set "usbethaddr" as an environment variable and it works nicely. I just used the last random address but I can set the right one that way.
That works only on rpi downstream kernel. Since the smsc driver is modified to get this working. Guillaume

I then set "usbethaddr" as an environment variable and it works nicely. I just used the last random address but I can set the right one that way.
As Guillaume mentioned this is a special hack for the downstream kernel that *should* already work. I'm surprised it doesn't. If you have some time on your hands, please try to debug down why usbethaddr doesn't get set automatically - the code for it is in U-Boot. Going forward, we will move to a more standard EFI based booting mechanism though, which means we can't access U-Boot variables in the kernel command line anymore. So we need a different mechanism to pass the mac address into the kernel. The "usual" way to get things from firmware into the kernel is device tree. The patches I pointed at in the other mail enable support for exactly what we need, so we're getting close to a clean solution. This should also help us on other boards that have ethernet attached via USB, such as the Arndale ones.

The MAC address seems to be RPI's prefix b8:27:eb plus the last 3 bytes of the serial. This big problem is not how to fetch the 3 bytes. It's how to pass

This really is a kernel problem, not a U-Boot one ;). So I asked on the #armlinux channel. Apparently someone else felt the same pain on other boards and so we have all the infrastructure in place soon to deal with this via device tree: http://www.spinics.net/lists/linux-usb/msg136469.html https://lkml.org/lkml/2016/2/3/621 With these (switching to upstream for RPi will only become realistic within the 4.6 time frame anyway) and the existing logic in U-Boot to write the mac address property for ethernet devices, all we need is a small device tree patch to explicitly list the usb ethernet adapter!

What's missing in 4.5? I tried and didn't get any serial output.

Apparently sd card access, touchscreen support and rpi3 support are problematic areas: http://ht4u.net/news/31929_linux_45_mit_support_fuer_uefi_amd_und_raspberry_... 3d acceleration support is also supposed to get a significant boost with 4.6: http://www.phoronix.com/scan.php?page=news_item&px=Linux-4.6-RPi-Faster-3D So I think it's reasonable to provide an upstream based image for the RPi2, but we should hold back with a real switchover until 4.6.
