I do a similar thing, mounting an extra partition as read-only using /etc/fstab.
I my home, i have a symbol link to the actual startup script on the extra 
partition.
It is easy to remount the extra partition read/write when i have to update a 
project (which is usually simply a transfer from my laptop using rsync)

best, Thomas

Managed to shrink the existing filesystem in /dev/mmcblk0p2 using
resize2fs as well as the partition using fdisk. 
Created yet another partition /dev/mmcblk0p3 with an ext4 filesystem
which now gets mounted as home with the boot option
home=/dev/mmcblk0p3

There might be more elegant ways of doing this, but it works fine for
me.

thanks Chris and list again,

Thanks for that link! In this case I could run the patch as root anyway
I think.

Interestingly, starting pd from /opt/bootlocal.sh as root at startup
will make Pd use all of the CPU and hence produce stuttering audio. When
I change the corresponding line in /opt/bootlocal.sh to start as user tc
sudo -u tc /home/tc/myPdStartupScript.sh
Pd runs normally.

This is what I read from the docs and what I am currently using. Albeit,
I am having a 300MB sound file in my home dir and it being part of the
filetool.sh backup immensely slows down startup as the OS has to
uncompress the audiofile.

This is the method I am trying to use with a directory inside
/dev/mmcblk0p2 (the ext2/3 partition created by piCore itself, which I
did maximize to the full available space on the memory card).
Possibly I have to try to shrink that partition to make space for yet
another partition as dedicated /home. Any hints appreciated!

I think you could do this by settings the rtprio limit directly in: 
/opt/bootscript.sh


It seems that sysctl and ulimit can't set this but maybe this will help:

This might be off-topic, but has anyone managed to create a persisntent

You can use the command `filetool.sh -b` to backup a snapshot of the 
homedir to the SD card and it will be returned to that state on reboot.


There is also a kernel boot parameter to make the homedir persist 
automatically:

Thank you! This runs really great (compared to Pd on raspbian) on my
version 1 RPi!
I am currently wondering about realtime priorities:

When I launch pd as user 'tc' I get
priority 94 scheduling failed.
regardless if I use the -rt flag or not.

When I launch it as root using sudo with or without the -rt flag I get
[...]
priority 92 scheduling enabled.
memory locking enabled.
[...]
audio buffer set to 25
configuring sound output...
Sample width set to 2 bytes
running at normal (non-real-time) priority.
memory locking enabled.
/usr/local/lib/pd/bin/pd-watchdog
[...]
and htop shows a -93 priority value. 
I am curious what the message about non-real-time priority means?

Furthermore, does anyone know if the 'tc' user can be added to an
audiogroup, whose permissions could be elevated through
/etc/security/limits.conf (currently not present in piCore).

This might be off-topic, but has anyone managed to create a persisntent
home directory inside /dev/mmcblk0p2 (the ext2/3 partition created by
piCore itself, which I did maximize already)?

I am so happy my patch runs without dropouts on the RPi 1 and that it
boots so fast!

That's how i performed the compilation - the process, including the separation 
of the results into -bin, -dev and -doc packages should be made reproducible 
with some scripts. That is the wish of the picore repo keepers.

 If you want to install them in the meantime, please grab the files from

 The manual installation procedure is the following:

 Copy the package files from your local machine to the tinycore:

 echo puredata.tcz >> /etc/sysconfig/tcedir/onboot.lst
 
 and reboot the tinycore

 These are just the binary files needed to run pd.
 The doc/help files are in the puredata-doc.tcz package, the development

[Dan Wilcox]

It should work with makefile.gnu in src. We still need to update the autotools 
setup to support the "build in place" approach beyond the halfway symlinking it 
does now, so I wouldn't use the configure script et al. in the package for this 
yet.

 I followed your instructions to build the dist tarball:
 
> ./autogen.sh

 Then copied the tarball pd-0.48.1.tgz to the Raspberry Pi running Tiny 
 Core Linux and ran:
 
 ./configure
 make
 
 The resulting binary successfully runs a test tone Pd patch and outputs a 
 sine wave to the audio jack.
 
 Hope this helps!

The reason is that the "tce-load -i" command doesn't update the onboot.txt file 
which governs which packages are mounted at startup.
Hence the mount is temporary.

Hi Thomas,

Thanks for taking the time to do this.


If you want to install them in the meantime, please grab the files from 
http://l.g.org/puredata_tcz
The manual installation procedure is the following:
I was able to do a manual install quite easily by copying the 
puredata.tcz file over to the RPi and then running:


tce-load -i ./puredata.tcz

The reason this did not work before (which I emailed you about) was I 
had been doing `wget http://l.g.org/puredata_tcz` not realising this 
was your ownCloud server page rather than the package file itself.


One thing I noticed is your package seems to be mounted from a different 
location to all of the other packages:


$ mount | tail -n 4
/mnt/mmcblk0p2/tce/optional/libvorbis.tcz on /tmp/tcloop/libvorbis type 
squashfs (ro,relatime)
/mnt/mmcblk0p2/tce/optional/libogg-dev.tcz on /tmp/tcloop/libogg-dev 
type squashfs (ro,relatime)
/mnt/mmcblk0p2/tce/optional/libogg.tcz on /tmp/tcloop/libogg type 
squashfs (ro,relatime)

/dev/loop108 on /tmp/tcloop/puredata type squashfs (ro,relatime)

Note the mount source of `/dev/loop108` instead of `/mnt/mmcblk0p2...`.

In any case, running running a test tone patch produces sound with your 
package installed (despite the Alsa error):


$ pd -nogui test-tone.pd
priority 92 scheduling failed; running at normal priority
priority 94 scheduling failed.
ALSA input error (snd_pcm_open): No such file or directory

If I run with `sudo` the scheduling messages disappear.

Thanks again. Hope the package gets accepted!

Cheers,

Chris.

Re: [PD] Pd on Tiny Core Linux on Raspberry Pi

[Thomas Grill]

Dear all,
i have just submitted picore extension packages for pd-0.48-1 to the respective 
repertory.
I hope i have met all the requirements, so that the package can become 
canonical very soon.

If you want to install them in the meantime, please grab the files from 
http://l.g.org/puredata_tcz
The manual installation procedure is the following:

---

Copy the package files from your local machine to the tinycore:
scp $SOURCEDIR/puredata.tcz{,.dep,.md5.txt} 
tc@$TINYCOREIP:/etc/sysconfig/tcedir/optional/

then logon to the tinycore:
ssh tc@$TINYCOREIP
chown tc.staff /etc/sysconfig/tcedir/optional/puredata.tcz*
chmod 664 /etc/sysconfig/tcedir/optional/puredata.tcz*
echo puredata.tcz >> /etc/sysconfig/tcedir/onboot.lst

and reboot the tinycore

---

These are just the binary files needed to run pd.
The doc/help files are in the puredata-doc.tcz package, the development header 
m_pd.h is in puredata-dev.tcz .
To install those permanently, follow the procedure from above with changed 
package names.

best, Thomas

Sweet, good to know. I think it would be good if the Pd distribution tarball 
was built this way so you don't need autoconf/autogen installed to build.

Then copied the tarball pd-0.48.1.tgz to the Raspberry Pi running Tiny

Hope this helps!

Re: [PD] Pd on Tiny Core Linux on Raspberry Pi

[Dan Wilcox]

Looks like an issue with autoconf of your system. If we used a dist tarball 
with pregenerated configure scripts, this probably wouldn't be an issue since 
then autoconf and automaker are not needed, just gcc and make.

If you have any more time, you could try building a dist tarball on your main 
system and then build Pd with it using configure/make on the pi. Building the 
tarball is:

./autogen.sh
./configure
make dist

That gives you a pd-0.48.1.tgz with the pregenerated configure scripts.

I got this when I tried:

configure.ac:9: error: possibly undefined macro: AM_INIT_AUTOMAKE
  If this token and others are legitimate, please use m4_pattern_allow.
  See the Autoconf documentation.

Then when I tried to run configure:

tc@box:~/pure-data$ ./configure
configure: error: cannot find install-sh, install.sh, or shtool in 
m4/config "."/m4/config


I guess there are some additional build dependencies I'd need to install 
to get this working.


For now the old makefile.gnu route works great on this platform.

Re: [PD] Pd on Tiny Core Linux on Raspberry Pi

[Thomas Grill]

Dear all,
i have made a picore package for the pure data binaries:
http://l.g.org/puredata_tcz

The files need to be put into the tce/optional folder, and enabled in 
tce/onboot.lst if desired.

It is compiled for alsa only with -Os optimization and no specific architecture.
It can use tcl/tk if installed, fftw3 is currently not used.

Please let me know if it works for you.
If it does i will submit it to the official picore repo.

best, Thomas

Good to know that works Chris. The immutability is a

documentation on making a more standard read-write install?
I kinda gave yp last time I tried.

Out of curiosity, does the autotools build work as well?

And yes, a simple embedded-only distort would be *very* useful as I had 
problems with performance turning Raspbian in the past.

[PD] Pd on Tiny Core Linux on Raspberry Pi

[Chris McCormick]

Hi all,

This is fan mail for Pd on Tiny Core Linux onn Raspberry Pi.

TCL is a 50 megabyte GNU/Linux distribution which is 
immutable-by-default and runs very well on the Raspberry Pi.


I managed to compile Pd and got it to output a test tone which is why I 
am posting here. To do it yourself:


 * Install the alsa packages
 * Install the compiletc package
 * Compile Pd with `make -f makefile.gnu` inside the src directory
 * Run `pd -nogui mypatch.pd` from the bin directory

If you want to launch a Pd patch at startup add your command to 
/opt/bootlocal.sh


So far this seems like fertile ground as an alternative to the Raspbian 
distribution with its multiple-gigabyte bloat. Seems perfect for 
embedded Pd devices like guitar pedals, synths, and what-not.


Tiny Core Linux does not use systemd.

Cheers,

Chris.
