Absolutely, here it is:
https://mega.nz/folder/UZ1S0TrC#SPdeVesbpTHleJI0UtC5yw
It was installed as separate boot and root partitions. I used dd to archive and save them as .img files. There's a root user and a www user, so I'm guessing it ran/could run some sort of web service but I haven't looked into it. The root user's music folder has a couple scripts that play internet radio stations, not sure if either of those things come standard with Jlime or were from the previous owner.

Hi!
Short update - I got in touch with Arnd Bergmann, for now the Jornada 72x is not removed from the Linux kernel sources. Sadly I got absolutely no time to work on this - maybe someone else can try to get 5.x kernels running on the Jornada - it is definetly something in the Jornada specific code - other SA-1110 systems boot up with no problem.

Stefan is still trying to get this machine working again, so it won't
be removed in this round.

Does anyone have a mirror of the kernel 3.16.81 files as referenced on https://www.sp-net.at/doku.php?id=jornada_j720 ?

Also looking for the files mentioned at https://www.sp-net.at/doku.php?id=jornada_j720_devuanlinux and Bootloader, Kernel and Debian 9 / Devuan 2.1 rootfs.

Not sure if this is all in the files at https://nextcloud.sp-net.at/s/SQbqbX64QdZarop?path=%2Fkernel3.16.81 or not.

Apologies for posting to an old thread and thanks in advance!

Yes the files are all in there (click the "Download all files" button).

You may also be interested in this repository: https://github.com/dev-null2019/jornada7xx-linux

Where can the "Download all files" button be found??

The github repository appears to contain the source which is great, but...

I'd like to find the original kernel, modules, and rootfs as compiled by @_dev-null (Stefan)

I think you can download the whole repository, just click on the green "Code" button and "Download Zip" under that. It has the kernel folder and stuff in it, so. (For source code)

I tried the link for the kernel (3.16.81) from here: https://www.sp-net.at/doku.php?id=jornada_j720_devuanlinux
It takes a while to load, but there is a button on the top right for "Download all files".

From your link - https://nextcloud.sp-net.at/s/SQbqbX64QdZarop?path=%2Fkernel3.16.81

Look in the upper right corner. If you're on PC the button should just appear, on a phone you have to press the menu button as shown in my screenshot.

Whoa! I swear I clicked those links a hundred times but it was a 404

Anyway thanks for the patience, I get worried any time important links like these go dead. The nextcloud thing doesn't appear to be indexable by the archive.org.

Maybe it was temporarily down when you were first looking at it or something.

Hi guys,

I'm coming back to this after being absent from the HPC/Linux world for a while. I finally managed to replace the RAM chips on my J720 ROM board so that it now has 128MB, and then decided to try Linux again as that's is the only way to make use of the extra RAM. I downloaded the latest build from https://nextcloud.sp-net.at/s/SQbqbX64QdZarop?path=%2F and everything worked great (except that on params.txt I had to change "sda" with "hda" in my case). The kernel recognized my full 128MB upgrade and the system is a lot smoother from what I remember. Next step was to go online with it. I tried all my cards (aironet 340, belkin f5d6020 and linksys wpc 11 with prism chip) but none of them worked. I saw that the modules are present on the rootfs, but when I insert the card it can't load any of the modules complaining about missing symbols. It seems that this latest kernel wasn't compiled with support for those modules or some other missing link between them.

I then went on my archives and found a specific kernel version that @_dev-null compiled for me here: https://www.hpcfactor.com/forums/forums/thread-view.asp?tid=18740&st... with built-in aironet drivers. This kernel worked great with my aironet card, and also did work with my linksys prims card as well. I didn't change anything on the rootfs, just replaced the kernel on the FAT partition. I'm wondering if I'm missing anything on the instructions for this newer kernel or if is actually not working with the WiFi cards. Are you guys experiencing the same problem?

Also, is there a place where I can upload my working kernel copy? SCL maybe?
