OptWare for Kindle

[knc1]

You are bumping a 5 year old thread here.

No, not anything posted here.

You are mistaken.
Kindles more recent than the PW-1 are running the NXP (previously Freescale, previously Motorola), i.MX6 sololite soc, see:
https://cache.freescale.com/files/32.../IMX6SRSFS.pdf

The ARM, Cortex-A9, implements the ARMv7-A architecture.

Up until the K4, they were using ARMv6 CPUs, yeah (v6j, arm 1136jf-s). Since the K4, they switched to ARMv7 (Cortex A8, then A9).

EDIT: Missed a new page again, yay! ^^.

I'm aware. This was the most relevant place to ask the question. I'm not worried about arbitrary enforcement of ancient forum etiquette, although I'm sure you have some logical reason for being concerned.

Thanks for the info. I should have clarified, I'm running a K3. So long as optware-ng doesn't have v6 compatible builds, I won't be able to use it. If anyone has indeed figured out a way to run optware-ng on the K3, please let me know!

[geekmaster]

I bump ancient threads too if they are the most relevant.

Most social conventions and unofficial rules never made much sense to me, because they are all-too-often based on the same principles as the Five Monkeys Experiment and the Pot Roast Story. Standards however, an entirely different matter.

There is no need to limit yourself to Optware. I made a full debian root that works in my kindles, based on instructions posted elsewhere by twobob. More flexibility but (if not careful) more memory usage too. Swap files are the key...

Please start a new thread.
They are very cheap here.

New situation, new topic == new thread.

You said that v5 builds are available - use those.

Note:
There are reasons this thread has remained idle for five years.
But since you are convinced that only 'ancient forum etiquette' is involved, I will let you discover them yourself.

Some people bricked their kindles with optware loop mounts. A good (but hard) lesson to learn...

[knc1]

Plus, you can run 'normal' Linux distribution binaries from user storage, even when that requires using different system libraries.
I.E:
Use different system libraries **concurrently** with those the Kindle's firmware is built against.

The one worked example I provided can be found in the "ARMhf on Kindles" thread.

The maintainers of Buildroot even extended it to support the tool(s) required for the purpose.

Translation:
You are trying to re-invent a really bad wheel that has long ago been superseded.

To be fair, the last post before mine was a little under 2.5 years old but I understand it has been idle for a long time, and for what sounds like good reasons. The main reason I posted here was that I was directed to this thread via the Kindle Hacks Information wiki page, which presents this thread and optware as the most current package management solution. I figured other lurkers (as I formerly was) who are being directed here might benefit from some updated info.

I wasn't sure if ARM was legacy compatible, but now I will give that a try, along with researching some of the other methods that you and geekmaster have mentioned here. If I figure anything out or have any questions I will post a new thread.

Thanks all for the info

[NiLuJe]

As @GM experimented, unless you go so far back as to hit an ARM ABI switch, then, yeah, it's fully backwards compatible .

[geekmaster]

The ABI changed after the K1, but gmplay built for the K3 works fine on everything from the K2 to the KV (and probably the Oasis, though I need to publish my KUAL extension so somebody can try it without needing SSH).

I was rather difficult finding a toolchain that works on the K1, but I ultimately succeeded (as can be seen from the thread linked to the K1 "jailbreak" in the jailbreak index sticky thread.

I am curious though why some extensions pack two versions of executables for older and newer kindles (perhaps three versions if I add K1 support to them).

[knc1]

If the executables use Java, then it is because the libraries are different between keyboard devices and touchscreen devices.

Here is a little script to automate everything sorry for the multiple posts on an old thread but I can't seem to edit them.

Copy the script onto /mnt/us/ and make sure to chmod +x

[#] First run

./ipkg.sh

[#] After restart to mount only and export PATH
-m param i.e

./ipkg.sh -m

[#] Installing a package

ipkg -t /opt/tmp install nmap

[#]If you use a different console make sure to

export PATH=$PATH:/opt/bin

ipkg -t /opt/tmp update

Ipkg.sh
