Upgrading uboot has its risks. Unless you really know what you are doing, it is probably safer to put the wrapper around the kernel as described in the Debian email i included a link to.

What would be nice is if excito invested some time to really test this kernel, and package it up cleanly in a Debian package and put out an experimental update to use it.

There is talk of a new long term kernel coming soon, maybe v3.16 or v3.17, which Debian would adopt. It would be nice if B3 was ...

It depends on how old your uboot is. If it is too old, you need to put a wrapper around the kernel. See:

http://lists.debian.org/debian-arm/2012/08/msg00128.html

You also need to enable CONFIG_ARM_APPENDED_DTB and make sure the .dtb file is appended to the kernel. I've not used archlinux so i have ...

In light of the recent Heartbleed-Bug I feel a little uncomfortable with my B3 running Mouette's 3.0.xyz Custom Wheezy Kernel which is unable to update OpenSSL to a safe version.


There should be no relationship between kernel version and openssl version. You should be able to upgrade OpenSSL ...

@asl did you submit that patch? Did it get accepted?

Yes, it is in linux-next now, and should be part of v3.15.
So that means the B3 is probably able to boot Kernel 3.15+ without updating the uboot-image?

You need a bit of magic when creating the image. See:

Here is how i build the uImage:


/#!/bin/bash

tmp=$(tempfile)

# disable l2 caches
devio >> $tmp "wl 0xee3f3f11,4" # mrc 15, 1, r3, cr15, cr1, {0}
devio >> $tmp "wl 0xe3c33501,4" # bic r3, r3, #0x400000
devio >> $tmp "wl 0xee2f3f11,4" # mcr 15, 1, r3, cr15, cr1, {0}

# flush caches
devio >> $tmp ...

It is not possible to turn L2 cache off in the kernel. By the time the kernel is running, it is too late, corruption has already happened. There is some discussion of this here:

http://www.spinics.net/lists/arm-kernel/msg297709.html

What i do on my hardware, which has the broken u-boot, is ...

I think you missed the part about uboot.

Anyway, i went back to the broken u-boot and appended the necessary hacks to turn off the L2 cache so that a modern kernel will boot.

My port for mainline will probably appear in Linux kernel 3.15. You can see the patches here:

http://www.spinics.net/lists ...

Did you ever get networking working in uboot?

I have the same issue:

• Net: Net Initialization Skipped
  No ethernet found.

Looks like some configuration is missing somewhere.

You can use any of the standard LED trippers:

lunn@b3:/sys/class/leds/bubba3:blue:active$ cat trigger
[none] timer heartbeat default-on phy0rx phy0tx phy0assoc phy0radio phy0tpt

Here phy* is referring to the wlan PHY.

However, this is only currently available in my kernel. I ran into problems ...

Hi Johannes

Yes, i'm on a B3.

WiFi? Is this the EEPROM containing the regulatory information?

Do you use a COTS card? Can you tell me what it is? Where i can get a data sheet?

Humm, interesting. In syslog i see:

Mar 29 14:48:31 b3 ftd: Torrent Chown failed: No such file or directory
Mar 29 14:54:47 b3 ftd: Torrent Chown failed: No such file or directory

So it tried to chown() some files, but hard to know which. Looking at the code, it chown()s a few different things ...

Hi Cheeseboy

Thanks for your reply.

I put this into hacking/development because i think it is a bug. I would of preferred to of put it into a bug tracking system like bugzilla, but i've not yet found one. Also, it probably does not affect many people, only those with NFS server to export the ...

This is something on my TODO list, but for B3. Since this is basically a Debian image, and my current tunnel end point is a debian machine, i'm not expecting too many problems.

What i can say is that B3 works fine as a simple IPv6 device. It got an IPv6 via router advertisement. ssh, www, ntp etc ...
