Good to know, it bugs me that I haven't been using my M300's for
anything, old tech but nice looking enclosure!

Yes, I'm still using it with the hard disk connected to the sata port
without any issues.

The only alpine packages I've updated are squeezelite and the kernel to
5.5.19.  I really should update the kernel but the m300 has been solid.

I'm running LMS from git on it now so I haven't been updating those.

Cool! I was watching this thread but didn't have any ideas to jump in
with, glad you got it working. Your timing is funny because I was just
thinking about the stack of M300's I have and whether I should go back
and update all the armel packages to see if I was still having the data
corruption issues that made me give up the first time around.

@ralphy, are you still using the M300's with Alpine? Any issues?

Dug through the /var/log/message file on rootfs, turns out the pogoplug
could not get a DHCP address from the router.

Assigned a static one at /etc/network/interfaces, and lo and behold:


Code:

Welcome to Alpine!
  
  The Alpine Wiki contains a large amount of how-to guides and general
  information about administrating Alpine systems.
  See .
  
  You can setup the system with the command: setup-alpine
  
  You may change this message by editing /etc/motd.

Re: [SlimDevices: Unix] Alpine Linux on Dell M300

[pseudov]

Thanks for the quick reply.

I believe sodface's armel_genrootfs.sh already enables PermitRootLogin.

I also tried adding those 4 lines to /etc/securetty, but still couldn't
ssh.

Here's how the boot process goes on the pogoplug_v4:
1. power up, blinking green led light
2. netconsole begins to display u-boot log | blinking green led light,
pogoplug can be pinged
3. after netconsole logs end with "Starting kernel...", led light turns
to solid orange, pogoplug cannot be pinged (Destination Host
Unreachable)
4. after a while, led light turns solid green, but pogoplug still cannot
be pinged

Looks like the boot loader was successful.

That's all the messages you'll get using netconsole.  Output from the
kernel booting is not displayed.


Did you enable ssh connections as root by adding

PermitRootLogin yes

in /etc/ssh/sshd_config

and these lines to the bottom of /etc/securetty

pts/0
pts/1
pts/2
pts/3

in the rootfs before trying to boot?

Hi ralphy,

Sorry for reviving this old thread. I, too, have a dockstar running with
bodhi's latest kernel and u-boot. I think running Alpine on the dockstar
would really help, given the limited memory on this device.

I've been trying to get Alpine to run on my dockstar for a week, but I
seem to have run into a dead end. I'm kind of new to u-boot, and
troubleshooting is hard without a serial connection.

I have netconsole enabled on a very similarly configured pogoplug_v4,
and here is as far as I get:

As per bodhi's installation guide, everything is just on sda1, formatted

No other partitions on the drive. So far, I've tried the following:

Used sodface's armel_genrootfs.sh to generate the Alpine rootfs
Added alignment=2 to uEnv.txt
Played around with /etc/fstab

I would appreciate if you or sodface could point me in the right
direction. Thank you.

There's only 650 .apk files in the directory though which has me a
little confused.  The APKINDEX file must have more entries than there
are actual packages.  Need to figure that out.


Code:

[sodface@www armel]$ ls *.apk | wc -l
  650

Thanks for building the tzdata package.  I just installed it on the
dockstar and pogoplug pro.

As a test I have the pogoplug building alsa-utils and all the
dependencies ATM and there are a lot.

If it completes successfully I can zip up the lot and PM you a download

The M300 pictured in post 1 needs to be reloaded so I will test the
build script and post back.  I've setup another M300 as a build machine
just using the 16GB ssd that came with it, ok on space so far.

I'll get it added, I haven't really done a lot of testing so there's
probably more stuff like that that I've overlooked.

I don't have a problem sharing the key with you. I haven't really
thought through how that work.  I posted up all the packages I had last
night.  There's a APKINDEX.tar.gz file in the root of the repo that
reflects the contents of the repo.  I build some more packages locally
this morning and rsync'd my local build repo with the remote one.  That
works ok when there's only one local and one remote repo but with two
different locals updating the same remote I imagine it would be possible
to get some inconsistencies since there's only the one index file.  I'm
sure this is a solved problem I'm just not sure what the solution is.

Re: [SlimDevices: Unix] Alpine Linux on Dell M300

[ralphy]

Thanks for getting the repo setup and the rootfs creation script.  I did
script all the steps to create the dockstar fs using the rootfs file you
posted earlier, but that's a better option.

To set the timezone I had to download the tzdata armv7 package and
extract just the zoneinfo file for my timezone into the filesystem to be
able to set the clock correctly with ntpd.  Perhaps that would be a
package that could be added to the repo eventually?

I've had squeezelite playing on the dockstar with a Behringer UCA-202
all morning without a tick/pop using -a 120:::0.

I have a 2 core 850Mhz pogoplug pro that I'm thinking of setting up as
an alpine armel package build system, I used to use it for squeezeplug
builds back in the day.  If I do, perhaps we could coordinate using the
same signing key so I can contribute them to the repo?

Re: [SlimDevices: Unix] Alpine Linux on Dell M300

[sodface]

Here's a tarball for a script to create a root file system from the
repo:

http://www.sodface.com/repo/armel-rootfs-x86_64.tar.gz

It consists of the following:


Code:


  .
   apk-tools-2.10.4
  apk
   armel_genrootfs.sh
   busybox-links.txt
   keys
   s...@sodface.com-5e51d361.rsa.pub
  



I tested this on my Fedora x86_64 laptop, the included apk is Alpine's
static binary for x86_64.

Take a look at armel_genrootfs.sh and tweak as needed!  I think you need
to run it as root, not via sudo.

I think I have a partial repo ready, and by partial I just mean
everything I have built but not everything that's in the normal Alpine
repos.  It took me a bit to figure out a script to re-sign a lot of
packages so they are all under one key without having to recompile them.
I think I have it sorted.

Add the repo:

Code:


  m300-01:~$ cat /etc/apk/repositories 
  http://www.sodface.com/repo
  



My public key is available here:
http://www.sodface.com/repo/sodface-pub-key.tar.gz

Extract to /etc/apk/keys/

Code:


  m300-01:~$ sudo tar xzvf sodface-pub-key.tar.gz -C /etc/apk/keys/
  s...@sodface.com-5e51d361.rsa.pub
  



Run apk update:

Code:


  m300-01:~$ sudo apk update
  fetch http://www.sodface.com/repo/armel/APKINDEX.tar.gz
  main  [http://www.sodface.com/repo]

  dockstar:~#



Had to modify the rootfs to allow remote root ssh login as I don't have
the serial console cable connected.

I put boot and root on sda1 as that's how I already had u-boot
configured and I set alignment=2.


Code:

dockstar:~# cat /proc/cmdline 
  console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 
mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data) alignment=2

  Half:   0
  Word:   0
  DWord:  0
  Multi:  0
  User faults:2 (fixup)
  



A linux system using 7MB of memory, nice!  Well, 17 really, but 10 is
cache. Makes the 114MB free in the dockstar seem excessive.


Code:

Could you provide squeezelite and prerequisites packages? That will give
me something usefull to test with until the repo is ready.

Quick testing indicates this may have fixed it!  In fact, just :::0
seems to fix it also.  Thanks ralphy.

Will continue to test.  I was originally only planning on using this as
an LMS / file server but it would be a nice bonus to have working audio
out too.

I've learned a lot working on this.  One thing that initially almost
made me give up was issues I had with Alpine's apk package manager.  It
took me a while to get to the point where I had a bootable base system
and then the one application that I wanted to work correctly, the
package manager, didn't.

If you are interested, you can read about it here:
https://lists.alpinelinux.org/~alpine/apk-tools

Subject is "APK Package Name Issue on armel port".  The developers were
great and commited some patches to fix the problem (fixes included in
the tar ball you got.)  It was down to unaligned memory access, which
after I knew what I was looking for I was able to read up about but I
wouldn't have figured it out without the Alpine dev diagnosing it.

I haven't quite figure out why yet, but, Alpine on the pi zero w
defaults /proc/cpu/alignment to 2 (fixup) and I don't even think
unaligned access is an issue on that architecture (not sure) but on the
armel port I'm working on it was defaulting to 0 (ignore) which
basically caused all the weird stuff with the package manager.  I'm
setting alignment=2 now as a kernel boot param, even though they fixed
it in apk's code, just in case there are other apps that might cause
problems.

I tried to convince the guys over at the doozan forum where they were
working on this device (I used the .dts and kernel config there as a
starting point) that it was a potential problem on their Debian loads
but I don't think I was able to get my point across.  Not even 100% sure
I'm right but I think I am.

See starting here and on:
https://forum.doozan.com/read.php?2,61344,96059#msg-96059

Anyway, just food for thought and if you have any opinions on anything
I'd like to hear them!

Guess I jumped the gun!  Something to look forward to.

That's no problem. Kernels tend to be device specific and I already have
a couple kernels for the devices I want to try.

Try turning mmap off -a 120:::0 and if still no difference try
increasing 120 to 200, 300 and 400 just to see if you can get clean
audio with -a.  Beyond 200ms is really much higher than should be
needed.  Could be a specific decoder issue as well, try several
different audio formats if possible.

Re: [SlimDevices: Unix] Alpine Linux on Dell M300

[sodface]

@ralphy, here's a link to download the basic root filesystem that I last
used to boot from (I made a bunch, this is the most recent):

http://www.sodface.com/res/tmp/202002270337-armel.tar.gz

Let me know when you have it and I'm going to take the link down.  I was
going to post all this stuff up and put a repo online etc. but I wasn't
quite ready to go just yet.  A few notes on the tar ball:

- root password is alpine
- the fstab is setup for my m300, a small partition for /boot on
/dev/sda1 and / on /dev/sda2
- I was having the script create a 1GB swapfile but I disabled that for
this download and commented it out in the fstab creation
- I didn't add any kernel modules
- no kernel or initramfs

Here's the list of packages in the download:

I don't know if this is of any use to you in this form, maybe for
initial testing?  I've got 400+ packages built so far but like I said
I'm sort of still in the process of organizing the stuff and prepping
the website.  I've also put myself in a silly spot because I cross
compiled a bunch of packages on my laptop with one public/private key
pair and compiled a bunch more packages natively on the m300 with a
different public/private key pair.  I think I've figured out a way to
re-sign all the packages to be under one key but I haven't done it yet. 
Still need to test it some more.

In the meantime, let me know if there's something specific you need.

Would you be willing to share a tarball of your Alpine armel root
filesystem?  I have several armel based systems that I'd like to use
with Alpine linux.

Make sure your squeezelite process has permissions to raise the thread
priority, or just run it as root.

Try adding *-a 120* to the squeezelite command line.  If you still
experience the pops/clicks then try *-a 16384:4096*
