I tested the Alpine distribution. So far I'm very satisfied with it.
Just a few things I noticed at usage:
- the embedded onscreen keyboard is less pratical than the kindle or kterm ones.
I don't know if there would be a way to use them instead...
- the power button doesn't put the device into sleep. Maybe just an option to configure.
On the other hand the nice thing is when the device goes into sleep after a while, it no longer display kindle ads but a custom screensaver
- also the limited space in /mnt/us... due to alpine image and installation files.
As I used automatic installation with kual extensions, I didn't see it put alpine.zip taking 300mb+ for installation.. Then I saw it could be deleted. So I got some storage space back then.
The things I could do so far which were not possible or straightforward before:
- install linux packages using alpine apk (could make git works )
- web app works out of the box in chromium which I consider a great improvement for projects
The things I'm still looking to do:
having usb serial communication works... need to investigate further...
At last resort I remember someone during serial jailbreaking including a bluetooth serial transmitter inside.. but I hope a simpler software solution exists...
