Is the GRIII linux based!?

I've downloaded the GPL sources tar from the link on the manual, and got this... a linux-kernel-v1.0.0.tar.gz file!

Code:

Best,

...but it also has systemd so we might just say "PENTAX IS DOOMED™ " and call it a day

The Squirrel Mafia · 03-15-2019, 07:59 AM

Interesting! I Linux, you Linux, even Ricoh Linux! Hahaha!

But yeah! That could bring up some interesting "hacks" in the future.

**bobbotron** · 03-15-2019, 08:08 AM

Very interesting! Man, that's weird to think that a whole OS would boot up when you turn the camera on... I mean I get this is technically what always happens, but my experience with linux is something that's running a lot of services.

Super neat.

aaacb · 03-15-2019, 08:49 AM

Someone needs to allocate memory and handle interruptions, so why not use the option that's free and stable. There are embedded Linux distributions, wondering if one could figure out what this is based on. Nice find!

danielblues · 03-15-2019, 09:16 AM

Here goes the link Open Source Software (OSS) | RICOH IMAGING
Kudos to Ricoh for releasing it.

Embedded Linux is fairly common*, though it is probably a bit premature to suggest that the camera's firmware in general is Linux-based or even exposed at any level to running modified or side-car code ala Magic Lantern.

Still though, this discovery is very interesting indeed.

* The Android operating system is based on Linux kernal. Note the busybox archive to get a clue as to the flavor of the embed and how it is being used. It is possible that it the presence of this tarball is the reason for the extra effort for license disclosure. The folk at BusyBox are famously litigious.

The nearest experience I have with embedded linux was recompiling a custom openwrt, not very useful, maybe a change to the milbeaut architecture.

Code:

A hack friendly Ricoh/Pentax future would be great!

It likely boots as BusyBox. My DSL router runs on that package and it is unremarkable once that part is understood.

Na, they're just part of an old Debian group

Will you be making a GIII emulator?

Sorry, no time or knowledge for that. But would give a try on adding some thing basic like a delete option to the wireless api web services (with and option for raw+jpg deletion)

This is really awesome! It'd be cool to learn more about it and see what level of changes one could make...

This is hilarious!

Edit for those unfamiliar with Linux:
systemd is/was a core part of Gnu/Linux operating system that there is a lot of controversy over. People have had to make the choice whether to use it or move to something else in many different versions of Linux, so it's a bit of a recurring topic or 'meme'.

**kiwi_jono** · 03-15-2019, 03:07 PM

Thats great! I love open source software.
