Could you clarify whether this is NeTV model 1 or model 2? Where in the operating system are you seeing "chumby TV"?

Hi racingsimon,

I'm replying just to say how cool your project is and I hope you're able to get it working.

I've created a virtual machine using VirtualBox that should be a standalone copy of the Amazon EC2 instance.

It is about 18.4GB as a 7zip compressed file so I made a torrent file for it.

     http://www.legittorrents.info/index.php … p;active=1

I made a kernel change to enable CONFIG_USB_EHCI_TT_NEWSCHED to see if it would fix Issue with USB AUDIO but I don't know yet if it worked. I have no special knowledge of NeTV kernel internals; I just followed these steps in the wiki.

I created a grub2 background and after installing XFCE-4/LXDE for the graphical environment, I also created a desktop wallpaper for it.

Hi John,

This is so cool and such a great use of the NeTV!

I thought I heard you mention in your second video about a BIPAP -- just curious to know if you have a link to the unit and maybe its documentation (API?) on how you are reading the settings in realtime? I'm interested in how you accomplish this.

To adam, jjk and gwgchase, and others who might read this message.

A lot seems to have changed with the Amazon AWS console compared with the original Wiki article. I've struggled trying to follow the steps I found at Export Amazon EC2 instance to VirtualBox. I can't seem to get authorized to create a t2.medium instance that would have sufficient EBS disk space for ami-c0b3f692 (netv-prebuild-1.3). I've contacted Amazon's AWS Support but it's been almost a week and I don't have a support contract with them.

So I'm back to square one it seems. I have the bandwidth and would gladly be a torrent seeder for a VirtualBox appliance version.

Is there anyone who can help by exporting their working VirtualBox VM to an .ova file? You can contact me privately to work something out.



Hi DanCBooper,

I'm a very satisfied NeTV1 hobbyist/enthusiast so my feedback is based on my personal experience. I've not used my NeTV1 for a large deployment like what you're considering.

Realistically, you should probably wait until the NeTV2 units are available (I don't know when that will be) because the NeTV1 firmware is no longer maintained. Out of the box, your network connectivity on the NeTV1 is limited to wifi, which has some reliability problems, or via ethernet-over-USB where the current firmware is limited to one NeTV1 per computer (think 10,000 Raspberry Pi's, for example, each with an NeTV1 unit attached). If you have experience with embedded Linux you could customize the NeTV1 firmware however you need to; it is 100% open.

1. If you wanted to get an NeTV1 for a proof-of-concept, you would either create custom javascript on the NeTV1 itself, or use its feature where you can point the NeTV1 to a local server's URL that would also contain your custom code. There is a limit to the supported HDMI resolutions (see here and here) which is important to keep in mind. You would likely want to use the NeTV1 chroma key compositing for the live content.

2. Adafruit is the official (and only, as far as I know) distributor and at the time I'm writing this there are 19 units left for purchase.

The wiki page states the NeTV2 will be in the range $200-$250. You must have come across a more updated price if it is now closer to $650 -- what have you heard or read (do you have a URL?) about the current NeTV2 price, and shipping cost? The BrightSign is way out of my budget range unfortunately.

Hi justaway,

I looked up in the forums to see if there was a fix and I came across this thread.

I know you're saying you got all the same output but can you confirm the firmware version as it is very important:

chumby_version -f

Did you run into any problems at all when updating the firmare?

However, plugging it into the TV, I get a message saying 'Problem detecting input resolution' and it is followed by a blank screen(or the STB content if I plug in the STB as input).

When you get the blank screen, what do you have connected as input? The NeTV does require an input source. For the sake of discussion, what is the make/model of your STB?

I'm also unable to configure the WiFi through the command line.

The steps I use are here. Are these the same steps you're following? If not, could you post a URL to the steps you're using?

I get an error which says something along the lines of 'Read-only filesystem' when I execute the commands to configure the WiFi from ubuntu terminal.

That is very strange. What do you get when you connect via ssh and type the following:

mount | grep psp

For comparison purposes, I get:

root@localhost:~# mount|grep psp
/dev/mmcblk0p3 on /psp type ext4 (rw,noatime,barrier=1,data=ordered)

Hi Alberto,

NeTV user sredmyer was kind enough to document his (successful) efforts to have his NeTV use a remote HTML page. There are two consecutive posts that should get you started, and the first one is here.

One more question: is it possible by any means to use HTML items with transparency, instead of chroma key?

As far as I know, chroma key is the only method supported.

Hi jpencausse,

I'm also interested in seeing the code if you would be willing to share. Can you elaborate on what "hard to share the HTML" means? For example, does it mean you tried to share it already but this forum rejected it for some reason? At least you didn't write, "impossible" to share, so there's hope that it's some sort of obstacle that can be overcome. big_smile

Hi cavs,

I don't have DirecTV so all I can think of is to ask if it supports any of the resolutions the NeTV supports? Here's the list from Adafruit:

480p, 576p, 720p, 1080p/24, 1080i/60

If you can put the graphics on a web page, and the DirecTV can be configured for one of the above resolutions, it will probably work fine.

Hi lostphoenix,

I haven't experienced the issue you're having but you might be able to gather more info about what's happening if you monitor the NeTV's syslog port. If you go to the wiki section on USB Ethernet support and scroll to the paragraph that starts, "The NeTV makes extensive use of syslog" you'll have the info to get started.

Hi Mike,

Other than trying different HDMI cables, at this point I would suggest returning it for a replacement. The symptoms are sufficiently weird enough that there's more than just the no-video problem. The level of hardware experience and knowledge to troubleshoot this further is over my head unfortunately.


(7 replies, posted in General)

Hi Mike,

This is a good head scratcher. big_smile

1) It's a long shot, and I've only had this happen once, but check the disk utilization and see if any lines are at or close to 100%. This could cause the internal web server to not be able to start up.

df -h

2) Regarding the no-video problem, the thread How to debug input signal might be useful, but I think it more likely you'll want to read this post and use the  matchmoded utility to show what the NeTV thinks is the source resolution.

Hi Mike,

wasn't sure if it needed to be set up before it would pass the video through

Nope. Provided the video source (in this case, the cable box) is one of the resolutions the NeTV supports, you should see "Loading NeTV..." immediately as it starts to boot up. Click here for screen capture of what this looks like.

The default is for SSH to always be enabled when connecting via, but for wifi access you must first enable SSH. Since one of the main issues you are having is no video, I'm assuming you enabled wifi, and SSH over wifi, by doing something like the steps here and here.

We need to make sure you are on firmware version 43 before continuing to troubleshoot.

Without video, there are two ways I know of to check the firmware level.

You can type the following at the SSH prompt:

chumby_version -f

I acknowledge your statement that you can't bring up the NeTV web page, but for the sake of completeness and for the benefit of others who might read this thread, the firmware version can also be seen if you browse to, or on your LAN, Click here for screen capture showing the location of the firmware version.

Fantastic news! I'm particularly eager to read about the HTML API for NeTV2.

Hi jjk and jpencausse,

jjk: It sounds like you might have done this as part of a commercial product? If you can provide details on what you changed and how you did it, the rest of us might be able to make generic changes so you wouldn't have to worry about revealing too much. I might have enough C experience to help. Can't promise anything. I don't know java or javascript.

jpencausse: Do you mean you're using the "Remote"  event sources described at https://kosagi.com/w/index.php?title="App"_development ? What is the limitation you're running into?

(Note to myself: Never got email notification about any of the activity on this thread. Stumbled on this by accident.)

Hi Donnie,

I had the same experience in having to disassemble my NeTV in order to update the firmware. I inserted a new step 2 in the assembly instructions.

The Twitter login authentication is broken. The widgets that do a search-only do not require authentication and should work.

You can permanently configure wifi by following these steps.

For anyone else interested, I believe jpencausse is referring to NeTV2 Main page.

Hi CC,

I don't know why you'd be getting "unable to fetch packages." The way I've upgraded firmware that has always worked for me is to follow the steps in this post. You will lose any changes you've already made on the microSD card.

Hi RandyInLA,

As far as I know Adafruit is the only distributor.
