Thank you Andrew. Yes, after changing the resolution down to 1280x720 via ssh & reboot, the display was up & running!

And, thanks to all especially Diana for your constant follow-up.

If the system is booting, then it will get an IP address via DHCP and should be pingable - else there is a basic issue with the boot and it is not even getting started.

Hi all!

Same problem here: I burned the ubuntu-lxde-14.03.06-p16g1.img image, I can access it by ssh but I got no hdmi signal.
Power led is green on, ethernet green led is on and stable and the amber one is blinking sometimes as it should be I guess...

I tried this xorg.conf:

Section "Device"
Identifier "Card0"
Driver "modesetting"
Option "ShadowFB" "True"
Option "SWCursor" "True"
Option "HWCursor" "False"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
SubSection "Display"
Modes "1280x720"
EndSubSection
EndSection

Nothing again....:( Could you please give me some directions? I want to use my parallela as a desktop machine.

p.s.: I noticed that xorg.conf file was empty before my editing above
I got an asus hd multimedia monitor

EDIT: parallela board doesn't work with my asus hd monitor but it worked with a recent lg hd tv. The NON COMPATIBLE monitor is: ASUS VE228HR multimedia
Could you please try to improve the hdmi compatibility with the next ubuntu images? thanx.

thanx, all the best.

The "offical" image is this one.

http://downloads.parallella.org/ubuntu/ ... sty/image/

Can you help out and tell me why you used the ubuntu-lxde-14.03.06-p16g1.img?

Seems like we may need to clean up some links...

Hello,

thanx Andreas. I tried the official image but I get the same no hdmi signal. I changed nothing inside the original xorg.conf that comes within the image. Everything seems to be fine except for the video output 'cause I can reach parallela board by ssh and all the leds are ok. Some tips for fixing the hdmi issue? My asus hd monitor is fine with an odroid arm device, cables are ok.

EDIT: Tried the 1280 resolution mode editing the xorg.conf. via ssh, nothing new: HDMI NO SIGNAL :(
please help

all the best

Hi,

I got my image from here : - ftp://ftp.parallella.org/sd_images

That link is still active.

I was blaming my HDMI problems on my monitor, but on reading the above have downloaded the current file :D . However while I have no problem downloading, unzipping and writing ubuntu-lxde-14.03.06-p16g1.img to the flash drive and getting the computer to boot and appear on the network, I cannot say the same for the official current image :? .

I have now downloaded the current image 4 times now and still do not get a bootable image on the flash drive :!: . I have rewritten ubuntu-lxde-14.03.06-p16g1.img to the flash card and the computer boots as I am writing this message :D

I am using Windows Vista 64 bit ultimate, winzip and win32 disk imager. The flash drive/card was supplied in the accessory kit I bought.

Could the current image be checked please?

Regards,

Paul

Ok, so I managed to get the necessary stuff for my Parallella a month after receiving it, and HDMI is no worky:

1. Parallella SKU? (SKU A1010X0?)


SKUA101020 (edit: I just checked, the chip is definitely XC7Z010, not sure what's with the SKU; also, that aluminium adhesive pad on the heatsink doesn't seem to make contact very well, it's sticking mostly around the edges)

2. What type of fan are you using? (e.g. 40mm, 5V, 0.2A)


100mm USB fan, powered separately, stock heatsink stays cool to the touch (haven't had time to machine an adapter for a chipset-style 50x50mm cooler - those giant caps are annoying)

3. What PSU are you using? (e.g. 5V, 3A)


5V, 2.5A

4. What HDMI cable are you using? (e.g. microHDMI-HDMI, microHDMI-DVI)


microHDMI-HDMI->HDMI-DVI adapter

5. What monitor are you using?


Dell 2001FP - another HDMI-DVI cable works fine with desktop (some cheap Radeon card with HDMI output) and Raspberry Pi; I have another DVI-DVI cable somewhere, so I can test the adapter when / if I find it, but I kinda doubt it's the adapter or the cable (both are brand new)

6. Linux image? (e.g. ubuntu-14.04-140611.img.gz)


ubuntu-14.04-140611.img.gz

7. Kernel? (e.g. kernel-hdmi-140603.tgz)


kernel-hdmi-default.tgz, as linked from the quickstart page (symlink to kernel-hdmi-140603.tgz? http://downloads.parallella.org/boot/linux/ says they have the same mtime / size)

Code: Select all
root@linaro-nano:~# uname -a
Linux linaro-nano 3.12.0-g0bc9c3a-dirty #6 SMP PREEMPT Wed Jan 29 10:25:25 CET 2014 armv7l armv7l armv7l GNU/Linux


8. FPGA bitstream? (e.g. parallella_e16_hdmi_gpiose_7020.bit.bin)


parallella_e16_hdmi_gpiose_7010.bit.bin

9. Login via ssh, type this command and post the output. (Make sure you are connecting the monitor to the Parallella)


basically the same thing as whitlom on page 2: it thinks HDMI is disconnected (it's definitely not, and the monitor goes into standby when the cable is connected instead of displaying the usual colour test image that bounces around when there's nothing connected)

Re: HDMI Not Working

Postby m0n5t3r » Wed Aug 27, 2014 2:14 pm

All righty, the plot thickens: I tested with my other monitor (also from the last decade) and a bunch of monitors at work (microHDMI-HDMI -> HDMI-DVI adapter), no luck; tried the big-ass TV in a conference room (it has 2 HDMI inputs), it worked.

The adapter is female HDMI to 24+1 DVI (unlike my other HDMI-DVI cable, this one has all of the DVI pins populated); is this the wrong adapter, or is the Parallella not outputting the right signals for DVI?

Edit: the adapter is fine, I just tested (PC -> HDMI cable -> HDMI-DVI adapter); so, it must be Parallella not providing the right signals somehow. The question is: is this fixable in the code / zynq bitstream, or am I out of luck? I assume the HDMI transmitter knows how to send what's needed, but maybe it's hardwired in a certain configuration, or it only implements part of the spec...

I have tried three different DVI monitors and not had luck with any of them. However I have been able to use 2 different HDMI input monitors and have not had any problems.
