Parallella Community

Thanks for reminder. To enable serial port you need to edit and compile the device tree. Very simple and fast operation.(2 minutes) I will add instructions. Long term goal is to get serial port working by default.

Thanks that seems like it should be easy enough!

I'll have a look into the device tree edits necessary this weekend, I need to do first power up/test of my Parallella this weekend (received it last Friday and haven't had time yet) so I'll have a play with UART stuff after I've got that all going and report back. The readme here - has instruction for compiling the new device tree so plenty of info to get me started.

I tried latest ubuntu-14.04 using these files, I experienced some issues.

1f4abc33a27770570c235e3e3ccd0af2 ubuntu-14.04-140603.img.gz

1. no network

This is solved by "sudo rm /etc/udev/rules.d/70-persistent-net.rules"

2. no HDMI sound, SMPlayer stuck

not yet solved

3. no usb audio driver

I found that the USB audio driver disabled by kernel config.
Why did you disable it?

4. nano editor is not installed

Nano is a default text editor of Debian/Ubuntu distribution.

5. There are many ~files in the system.

The criminal is Emacs

shodruky,

Thanks for the feedback!!

1.) Sorry, link on the create-sdcard page was outdated, please try again. The right file to download (now linked up):

http://downloads.parallella.org/ubuntu/ ... 611.img.gz

2.) The persistent rule issue should be resolved in the new one.

3). In terms of USB sound, I'll look and see, we might have grabbed an older kernel...stay tuned.

4.) Yes, I also saw the smplayer getting stuck in 14.04 at times. Seemed to be hit and miss? Did you try selecting different sound destinations?

I have tried this out tonight. Downloaded all new bitfiles and Ubuntu release and dd'ed to a new partition

I deleted /etc/udev/rules.d/70-persistent etc file with no effect.

My board is hanging at the following state of the boot.

@timbat, which FPGA bitstream and kernel are you using?

Regards,

Andrew

Hi Tim,

Can you try using the HDMI kernel and FPGA bitstream.

Cheers,

Andrew
