Parabuntu 18.04

[ajtravis]

If you're not aware of it, please have a look at the discussion about Parabuntu 18.04 at:

https://github.com/parallella/parabuntu/issues/19

I've just posted a comment about the USB PHY initialisation.

@xuminready: I believe one reason that Parallella has failed to become an equivalent to the Raspberry-Pi for parallel computing is that its USB PHY does not initialise reliably despite many people, including Adapteva, trying to find out the reason why. I would prioritise re-writing the USB PHY initialisation when you rebuild the FPGA code to make sure that the USB PHY is set up correctly. Adapteva have denied there is a USB issue and recommend the use of specific USB cables and powered hubs to initialise the USB PHY properly. However, in my tests and those of other people using exactly the PSU, powered hub and OTG cable the USB seldom initialises. This makes it very difficult to use the Parallella as a 'desktop' computer with a USB keyboard+mouse. I know it can be used with a serial connection to the UART or SSH if networked, but the USB is there for a reason, as it is on the raspberry Pi: To use the SBC with a USB keyboard+mouse.

Please help us to prevent Parallella fading to black!

Thanks,

Tony.

Hi, heyman.

I've been busy trying to find out why the USB _still_ doesn't work reliably...

The armhf port of "vivid" 15.04 is still available at: http://old-releases.ubuntu.com/ubuntu/dists/vivid/

Not sure if that will help you, but it might be worth a try!

Bye,

Tony.

Thanks Tony!
Will add that repo to the appropriate files and see what I can download.
I wish you luck on solving the USB issue so that we can move to a more modern version of Ubuntu

Unfortunately, that site only contains the Package.gz files - which are pointers to the locations, not the actual binaries.
No luck trying to get vnc4server

Hi, Jerry.

It's an APT deb repository, so you will find the packages in 'pool' e.g.:

http://old-releases.ubuntu.com/ubuntu/pool/main/v/vnc/

Unfortunately, the binary packages are not there for armhf, but you could build it from the sources...

HTH,

Tony.

Tony,

That did it!
Able to download x11vnc and I'm off to the races.
Many thanks again.
