I have (somewhere) a copy of the Linux kernel patch, which should
contain all the necessary information. I gather that copies of the
chipset datasheets were made available by Psion, but only to specific
Linux developers for the purposes of porting Linux, which is a great
shame. Now that Psion no longer exists there's nobody around to ask
about more liberal terms. (And I think it didn't cover some of the
netbook custom chips anyway?)

Hi Tony, David, and list,

Thanks for responding!

Note that there seems to be confusion in your messages between proboot (for the 5mx pro) and bookboot (for the netbook and malaybook).
Or am I missing something?

Other than that:

Adding proboot into a git repo sounds like a very good step!
I would certainly appreciate it.

I have not found time to look into Fuzix (yet) sorry.

Isn't the sourceforge website where we could/should aggregate the info?
https://linux-7110.sourceforge.net/

Sure, as it is now, the webpages need updating, but I would worry that
relocating would be beyond what we can achieve (in 2025). 

I am happy to (contribute to) updating the website, but would prefer to
have some more (positive) feedback from other mailing list participants
(hint hint), before giving that a go.

Note that I have not tested running proglue.pl an a 32-bit system (yet).
It could be that there are other issues than the ones my patch addresses.

Dual boot seems to be covered well enough by arlo (for all epoc-capable
machines), based on my current experience.
One of the main features of proboot is that it serves as good (good
enough?) documentation of the system image format expected by the bootloader 
on the 5mxpro.

Klaasjan

Re: [openpsion] [patch] proboot update for 64-bit systems

[David G. <dg...@co...>]

I do have a plan --- very much delayed, too many projects and not
enough free time --- to try and port Fuzix to my Series 7, so getting
thanks for your work on proboot. You said that it didn't work on 64
bit systems; this means that it generates correct images on a 32-bit
system, right? That should be straightforward to diagnose, then.

I wonder if it's worth trying to aggregate all the Psion programming
information in one place before it all vanishes from history?

Re: [openpsion] [patch] proboot update for 64-bit systems

[Klaasjan <kla...@gm...>]

Dear all,

Happy New Year! 
And apologies for sending too many messages, and for top-posting.

This is just to follow up on my message below, for the record.
Ater some testing: while the patch below allows building sys$rom.bin files 
on an amd64 machine, and the resulting file is recognized by the bootloader 
of my 5mx pro, it does not boot properly. 
Instead, the result is an empty screen, and the 5mx pro needs to be
rebooted to proceed.

Instead, I have now successfully used arlo, combined with the original
(epoc) sys$rom.bin, and the 2.4.37.9-5mx32mbpro linux kernel from 
widearea (http://widearea.org/ste/psion/) to have a dual boot linux/epoc 
system. For now I am happy with this result.

If there is (renewed) interest, I might make further progress and report
back, but for now I'll likely go back to silent mode.

Best, Klaasjan

[openpsion] testing (and proboot) as 2025 draws near....

[Klaasjan <kla...@gm...>]

Dear Tony and list,

As 2025 draws near, I had some spare time and was playing around
with a Psion 5mxpro (32MB). In the process, I found that Tony Lindgren's
proboot at  http://www.muru.com/linux/psion/proboot/current/ has issues
with building an sys$rom.bin file when running the perl script
proglue.pl on an amd64 host. Likely because the script assumes a 32-bit
host when discarding the two most significant bits to turn addresses
into file sizes. 

I'll send a patch file that seems to fix the issue once I have ascertained that this message makes it through to list (and hopefully also to Tony).

Best regards,
Klaasjan

[openpsion] compiler for arm linux 2.4.x kernel via chroot and qemu

[Klaasjan <kla...@gm...>]

Dear list,

Over the past few weeks I have been renewing my interest and experience 
with the openpsion/psilinux kernel source, and compiling and testing it.
Below is a brief summary of the initial steps, hopefully this will raise 
some new/renewed interest.

The first issue was getting a suitable compiler running. It seems the 
2.4 kernels need ancient versions (gcc 2.95 in particular), and 
compiling such an old cross-compiler then requires a chain of compilers 
working backwards from contemporary ones.

Instead, a solution that works for me uses debootstrap, chroot and qemu 
as follows. This seems not only much simpler than installing or building 
a suitable cross-compiler, but also creates a filesystem that is 
suitable for running on your psion device (once you have a booting linux 
kernel).

See below. Feedback appreciated. With enough positive feedback, perhaps 
this should go onto the openpsion website?

Enjoy!
Best,
Klaasjan

*** You need:
- a recent (non-arm!) machine running debian (tested with bullseye), 
with internet access, root access and several GB of free disk space

** On this machine, create a suitable debian arm woody chroot as follows
# most of the below needs to be done as root (use sudo, or sudo -i)

* install the required tools:
- apt install qemu qemu-user-static binfmt-support debootstrap
- update-binfmts --display | grep arm  # this should output:
qemu-arm (enabled):
  interpreter = /usr/libexec/qemu-binfmt/arm-binfmt-P
# also /usr/bin/qemu-arm-static should exist now

* make a filesystem suitable for this old distro (ext2 revision 0)
- dd if=/dev/zero of=./debian-arm-woody.img bs=100M count=20  # creates 
a 2GB file
- mkfs.ext2 -r 0 ./debian-arm-woody.img

* Create a debian distro on the image file (debootstrap first stage)
- losetup -f #  to create /dev/loop devices, only needed if these don't 
exist yet
- mkdir /mnt/debian-arm-woody
- mount -o loop ./debian-arm-woody.img /mnt/debian-arm-woody/
- debootstrap --foreign --arch=arm woody /mnt/debian-arm-woody/ 
http://archive.debian.org/debian/
- cp -i /usr/bin/qemu-arm-static /mnt/debian-arm-woody/usr/bin/
- cp /etc/hosts /mnt/debian-arm-woody/etc/hosts

* Complete initial distro installation (debootsrap second stage)
- chroot /mnt/debian-arm-woody/  /bin/sh
- mount proc /proc -t proc
- /debootstrap/debootstrap --second-stage --keep-debootstrap-dir
# some warnings, like:
apt-config: not found
dpkg: warning, architecture `arm-none' not in remapping table
W: Cannot find binary for checking sha256 checksums, falling back to sha1
I: Installing core packages...
...

* install compiler software
- apt-get install less bison flex gcc
- apt-get install dialog wget bzip2 patch


* check:
- gcc -print-libgcc-file-name
/usr/lib/gcc-lib/arm-linux/2.95.4/libgcc.a

* next steps would be getting a suitable kernel source and try compiling 
it. More detailed instructions for that should probably be a follow-up item.

Re: [openpsion] Kernel source and bookboot

Dear David, Ed and list,

Thanks again for the encouragement!
I have now put Bookboot on github.
See https://github.com/kj4l7k/bookboot
Hopefully this is useful; feedback welcome!
If more of 'my' stuff should be copied there, or if you have 
comments/suggestions, do let me know.

Best regards,
Klaasjan

Re: [openpsion] Kernel source and bookboot

[David G. <dg...@co...>]

A quick glance at that shows lots of juicy hardware details --- thanks very
much!

I can't promise I'll get this done any time soon, but at least I have the
data now. I know how rapidly things bitrot. Also, I will most likely need
to get hold of a serial cable from somewhere as I don't fancy trying to
debug via the screen, and they're going for sixty quid on ebay now...

Re: [openpsion] Kernel source and bookboot

Good news: bookboot was there! Also some different patches. I can't comment
on the patches particularly, Klassjan and Peter would be the best to help
there.

WRT fuzix, the nb can have 64MB RAM BTW!

I should try to scrape the whole of the old website and put it somewhere at

Re: [openpsion] Kernel source and bookboot

[David G. <dg...@co...>]

Thanks!

Looking at the patchsets on the website... there's not much there. In the
S7 patch (
http://www.yipton.net/content/psilinuxs7/patch-2.4.2-rmk2-np1-pvs2.gz) I
can see code for handling the keyboard and remapping the framebuffer, which
I assume is already set up by the ROM in order to display the boot progress
bar, but I'd expect to see some other drivers for things like PCMCIA or
even just turning the LEDs on or off. I know that at least some of this
should be generic SA1100 (serial?) but even if the LEDs are wired up to
SA1100 GPIOs there should be some S7-specific code for identifying which
one. Is there another bit I need?

Let me know if you find bookboot!

Regarding Fuzix: entertainingly, it uses a 16-bit value for memory size in
kilobytes, which means it can't handle anything bigger that 64MB. That's a
bit of a shame on a Raspberry Pi but luckily the netbook is smaller than
that. CF interrupts are a shame but as Fuzix does all I/O via busy waits
anyway I doubt it'll be a problem.

What'd be really nice is to see the documentation provided by Psion.
Unfortunately, as I understand it, this is only available to Linux
developers via a special agreement, and Fuzix isn't Linux... now that the
Symbian Foundation is defunct I doubt there's anybody left who could change
the agreement, sadly.

Re: [openpsion] Kernel source and bookboot

[Edward R. <edd...@go...>]

Sorry David this must have passed me by last time. I will have a look for
bookboot this evening. There's an area of the website that we used to store
files in that is only accessible by ftp by a project member these days
IIRC, which has some stuff that's otherwise lost. As to the kernel source,
that's available on Peter van Sebille's pages here
http://www.yipton.net/content/psilinuxs7/

You should be able to boot using arlo if all else fails.

Note though that Peter never did manage to get the pcmcia interrupts
figured out, since there is an undocumented ASIC on the 7/nb, and that
means the cf/PC card has to run in polling mode, with a significant impact
on performance.

Would be interested to hear of any progress you make, fuzix is a very
interesting project. Though I do think that, having an MMU and relatively
large amounts of ram, the 7/nb are quite overpowered for it!

Best of luck,
Ed

[openpsion] Kernel source and bookboot

[David G. <dg...@co...>]

Hello, assuming there's anyone still alive out there...

I'm interested in doing a Fuzix port to the Series 7; Fuzix should fit in
the limited resources better than Linux. Does anyone know where I can find
a copy of the most recent Linux kernel which I can use for reference? The
Linux-7110 website is pretty much bitrotted.

Also, I can't find a copy of bookboot, the tool for generating a bootable
os.img for the Series 7. The link in the HOWTO is dead and I can't find it
on the SourceForge site. Is that still around anywhere?

Thanks!

Re: [openpsion] Hardware docs & specs

[Ed R. <edd...@go...>]

Hi Paul,
Welcome! The documentation available is limited to the series 5mx. The
series 5 uses the CL-PS7110, which you can find the datasheet for online.
The netbook and netbook pro are documented only by the kernel source, and
there were major issues with the netbook port (interrupts from PCMCIA and
CF were not working, so they had to be constantly polled). The netbook pro
port is more-or-less complete though I think.

The 5mx "windermere" SoC is very similar to the CL-PS7110. In terms of the
documentation, I don't know how important the conditions attached to it are
these days, given how far removed the psion IP owners are from psion, and
perhaps that is a topic for wider discussion here on the list (I believe
there are still quite a few people subscribed here).

But the conditions I got when I received it were essentially to only
distribute it to psion linux developers, not to make it publicly available,
and to make sure that anyone I distributed it to understood and agreed to
the same terms. If you're fine with that I'll send it over.

Best,
Ed

Re: [openpsion] 2018 Psion 5mx & Debian Etch

[Ed R. <edd...@go...>]

Very nice. I have considered trying to update the 5mx kernel and get an
eabi userland on to it. However, I suspect new software would not run
nearly as well, and I now have a planet computers gemini. For reference,
the latest (2.4.27 IIRC) 5mx/revo kernel source can be found at
http://svn.exactcode.de/linux24-psionw . Tony Lindgren's early 2.6 porting
effort is also available at http://www.muru.com/linux/psion/kernel/

BTW: There is now a relatively easy route to wireless networking for the
5mx, in the form of an ESP8266 running SLIP
https://github.com/martin-ger/esp_slip_router

Also, Debian maintains plptools, which includes a fuse filesystem for
mounting EPOC device drivers over serial/IR. I am not sure if it could be
made to work in mac OS or not.

Would be good to see any further developments you make.

Best,
Ed

Hi,

Im sure there are quite a fel people still on the list :-).

I still have my Ericsson branded psion 5mx too, but haven't done anything
with it in years.

That pda looks kind of cool but I want to wait until someone has hands on
experience of it before I decide to buy, many indiegogo devices ended up
either not launching or being gimped, so you never really know.

[openpsion] Gemini PDA

[Ed R. <edd...@go...>]

Hi all,
I don't know if anyone still reads the list, but thought I'd mention this
just in case...

An indiegogo campaign has been started for a new device very much like a
psion. The case has been designed by Martin Riddiford, who also designed
the psion clamshells. It will purportedly dual boot android and Linux.

[openpsion] Linux on Psion 7

[David W. <dav...@ho...>]

Hello All,
                 Just bought a Psion 7 off Ebay and decided to try to 
run Linux on it.

Some questions if I may ?
1    I have formatted a 512Mb CF card with 30Mb vfat partition, 64Mb 
swap and the rest ext3.
       Which files go on which partitions?
2    I have read that a Psion7 won't boot from an OS.img so I am using 
Arlo, is my information correct?


Thanks in advance,

Dave.
