[SOLVED] [trimeslice] 3.1.10 kernel, systemd & avahi

[wonko7]

Hi all,

I've just installed arch on my trimslice. I want to use avahi so it can publish its services on my local network. Here's my problem: Avahi starts up fine, but after a while systemd kills it because of a timeout.

From the journal, it looks like the kernel is too old (but it's the latest available one on arch).
Is there a workaround for this?

Thanks.

The package linux-armv7 (3.17.2-1) works on this
You have to create your own boot.scr though, to load dtb and zImage
I have done it, look for sirderpalot on irc for help

[wonko7]

Ok, thanks, I got the latest kernel working with the following boot.script:

$this->bbcode_second_pass_code('', 'setenv bootargs 'console=ttyS0,115200n8 root=/dev/mmcblk0p1 rw rootwait'
setenv fdt_high 0x2C000000
setenv initrd_high 0x2C000000
ext2load mmc 1:1 4080000 /boot/zImage
ext2load mmc 1:1 5880000 /boot/dtbs/tegra20-trimslice.dtb
bootz 4080000 - 5880000')

[wonko7]

By the way, shouldn't this be documented on http://archlinuxarm.org/platforms/armv7/nvidia/trimslice?

[pepedog]

I could be. I could do that.
Can you say what doesn't work, ie sound/hdmi? Or is everything working ok?

[wonko7]

Everything works, sound, wifi (with the dongle), but I don't have a hdmi set up, so I can't say for that.

[cchandel]

I can confirm that hdmi works too.

This information should be on the trimslice page on archlinuxarm. Could have saved me the time and effort in trying to get the Fedora kernel installed just to get a modern kernel on this machine.

[pepedog]

Do you think the rootfs should have this as default, along with second boot.scr for sata?
Can't see anyone would have old uboot, but still......

[kmihelich]

The installation page has been updated with all new installation procedures, using our own mainline U-Boot (2014.10) and the linux-armv7 kernel. The default provided boot.scr will boot a rootfs from either the front full size SD slot, the side micro SD slot, or the first USB device it finds (which would typically be the internal drive if available).

Hi,
I'm getting the following errors :-

$this->bbcode_second_pass_code('', 'Scanning MMC card ...

Had to change boot.txt to

$this->bbcode_second_pass_code('', '
setenv bootargs "root=/dev/mmcblk0p1 rw rootwait console=tty1 console=ttyS0,115200n8 mem=384M@0M mem=512M@512M nvmem=128M@384M vmalloc=248M video=tegrafb"

ext2load mmc 0:1 5880000 /boot/dtbs/tegra20-trimslice.dtb
bootz 4080000 - 5880000')

To be able to boot. Rest all seems to be working fine for now.

Thanks for updating the wiki.
