I have successfully booted up Devuan on the Jornada 720 from a microSDCard (that I partitioned /installed using an older raspberry pi I had laying around). Many Thanks to Stefan's Wiki on installing Devuan on a CFCard....it works with a microSDCard using sdcard adapter to pcmcia slot. (As mentioned elsewhere ...it won't work from the jornada cf card slot).

I can run the apm command...and terminal...but have to learn how to load apps. Anyone help me here?

This is exciting...a new beginning for the J720!

Assuming it has Aptitude installed. Try 
apt-get update 
apt-get install <name>
Which pulls from http://deb.devuan.org/merged/dists/beowulf/main/ e.g. 
apt-get update 
apt-get install nano

Hi!
I dont know why this should not work from the CF slot. Did you get any errors during boot from the CF slot?

Please can you do the steps described here http://www.sp-net.at/wiki/doku.php?id=jornada_j720_linux_cfdriver and send me the output of these two commands?:

cat /sys/bus/pcmcia/devices/0.0/prod_id1
cat /sys/bus/pcmcia/devices/0.0/prod_id2

If you booted from the PCMCIA to CF/SD adapter then you are not able to plug in any network card.
You have two options to get programs to the Jornada:

1. Connect over the serial cable with a Linux host and use the network connection from it. (slow as hell)

2. Copy over the .deb files to your SD card with all required dependencies and install them manually (doable but sometimes very frustrating because some programs have many dependencies)

Regards
Stefan

Stefan...FYI I solved the problem and your great Devuan OS program NOW BOOTS FROM CF SLOT.

I found a solution on some linux website. I had set up the partitions on the Raspberry Pi using the microSDCard slot and made it bootable from the fat partition 1... and then loaded your tar files on it...then the microSDCard was placed in its sdcard adapter...this SDCard was then placed into an SDCard to CF (type 1)card adapter but ==> would stall on boot. When the SDCard (only) was placed in a SDCard to pcmcia adapter==> boots into Devuan desktop.

The FIX: Place the SDCard in the CF Card adapter, place this into a USB to CF Card adapter and plug it back into the Raspberry Pi, open terminal and cfdisk, select partition 1, remove bootable setting by clicking on boot option, then Write to disk...followed by resetting it to bootable...and write to disk(this time in the cf card adapter). It now boots from CF Slot! I then placed an Nec 2000 wired network card into the pcmcia slot and thanks to your preinstalled network driver modules...it connected to the network and internet for downloading!!! Sweet Success!!

Question: I need super user credentials....password...where do I find it???


C:Amie. Thanks for your post...once the above was taken care of I was amazed and pleased when I typed in apt-get update and it really took off updating/downloading files!!

Needless to say, I am quite excited...and will continue my experimentation. Photos will follow with links regarding the various adapters used...but CF cards are no longer required to make the Devuan Os function (from the CF card slot) on the Jornada 720!

You can install packages easily with apt to the CF card when its connected to the PC and mounted as a drive.

Then use qemu and a systemd-container to start a shell running in arm emulation on the CF card and use apt in there to install packages.

Install required SW on the host computer:

$ apt install qemu binfmt-support qemu-user-static systemd-container

Then, assuming your CF card is mounted at /media/CF

$ systemd-nspawn -D /media/CF

Now the filesystem from the CF card is mounted in the container and using qemu to run the binaries in there. You will be in a shell session in on the CF card now, in particular, running apt-get install ... will install binaries from the arm repository on the CF card.
When you‘re done, use exit und umount to correctly unmount the card.

Just to clarify Joval, apt-get update just updates the package list from the repository server. To actually execute the update 
apt-get upgrade 
apt-get dist-upgrade

FYI...Boots readily from the cf slot if the sdcard is partitioned and formatted while its in the sd to cf card adapter and that in turn in a cf card to usb adapter. This done using a Raspberry Pi 2 B+...running their linux/debian derivative OS: Raspian (now Raspberry Pi Os), via the terminal app.

Presently successful using a 16Gb sandisk Ultra plus microSDCard partitioned as follows:

Partition 1 sda1 10 Gb Fat32 (not Fat 16).

One advantage is Windows, Win CE, and linux can read Fat32, (Windows 10 can't read Fat16) ...so easy to transfer files with a USB adapter. This was an older scdard I had previously formatted as Fat32 and 10GB...I did not alter this partition other than to make it bootable and to copy the boot files to...I did not delete and create it...so didn't delete pre-existing data. It has several Gb of music/songs and also the total HP backup for the Jornada...so when I reboot back to wince I can do a fast restore to it's prior state (except time date change etc.)

Partition 2 sda2 5.6Gb ext4 to which all the tar.bz system files were extracted.

Partition 3 sda3 208Mb linuxswap ...all of which seem to be recognized on duvuan boot up.

I'll be trying out some bigger microsd cards later...like the FlashAir wifi sdcard!

This has been as rather FUN, if not intense, journey into the Linux world . Many thanks to Stefan, C:Amie , Ntware and others who somehow saved my hpc's soul...or at least kept me heading in the right direction!!!! Happy Thanksgiving to and for all the HPCFactor members !

More to follow

TimoBO, great suggestion but when I tried it on the raspberry pi I must have the sdcard mounted wrong...it loaded the new apps on the raspberry pi ...not the sc card/cf adapter card. How do I set up the systemd-container and mount the sd card to it. Is there a tutorial somewhere?...you're way ahead of me here. Thanks in advance.
