I have installed QNX 6.4.0 neutrino on an unused x86 box. It's all working fine, I can run my test code on there via the network connection (qconn).
However the sound does not work. When I click the audio settings I get an error, similarly if I run my code it can't find an audio card.
I had an on-board sound card (built-in). Running io-audio, I was not able to detect it. So I went a purchased a new off the shelf PCI sound card (CMI-8738), this also failed to be recognized by QNX.
When I run "pci -vvv | less" I am able to see both audio devices are connected (and I can see in the BIOS as well).
I read somewhere that I need to get some driver called deva-ctrl-cmpci.so, but I can't find that anywhere.
What can I do?

I'm looking to install Linux onto an Intel Galileo Gen 2 utilizing this and this via installing onto an SD card.
I believe I have successfully done this, as during the boot sequence I am able to select Linux to boot from, however as soon as it starts booting from Linux, I am unable to interact with the Galileo anymore by say typing in my username and password when it comes time to login.
I'm unsure if my peripheral setup is wrong, if I need to install some more drivers to support I/O or something else.
I am viewing the logs from the Galileo via an FTDI cable and currently have a keyboard plugged directly into the Galileo.
Log data
When I boot the Galileo, this is what is logged.
Interestingly, the
flashing cursor stops flashing and is just steady when I get to the
login screen, as if the device is sort of frozen
However if I then
say connect a keyboard, it recognizes it and outputs this log data.
Solved! Turns out it was a faulty FTDI cable!
For some reason, I can only remotely control a server containing FPGA (Intel Arria 10 GX FPGA). But when I use the command in Intel OpenCL for FPGA to find the driver, I cannot find the FPGA device that can be used.
The command is as follows:
aocl diagnose
Output result:
enter image description here
Later, I used hardinfo to check whether FPGA is included, but unfortunately there is no useful information.
The only thing related to FPGA is that I found two files about fpga under my server (Ubuntu16.04). Since I am using FPGA for the first time, I don't know what this file represents.
enter image description here
In addition, due to network problems, I have not yet been able to install OPAE for testing. I would like to ask if there is an easy way to verify whether the FPGA is successfully inserted into the server.
You can check with lspci | grep "FPGA". The lspci command lists all devices connected to a PCIe slot, whether a driver is installed or not. If you find the FPGA in the list of devices, it is installed in the PCIe slot on the mainboard.
Pretty new to ChromeOS as have tried googling but can't find anything of how to write something to control my USB Nes Controller to use it pretty much as a keyboard to play emulators online, much less system demanding than running it all through linux.
that product page doesn't say how the device presents itself to the OS. is it a keyboard ? if so, it should "just work" ...
you can find out by plugging it in and then going to chrome://system and look at the lsusb and dmesg output. or look at this page for getting a system debug log.
if it is an arbitrary device, there is the Chrome USB API, but that only works for dedicated apps. i don't think you can write an interface as an extension which would allow working with any website.
Recently, my computer has been acting rather strange. All audio is muted and any time I try to watch a Youtube video the player ends up crashing. I can't seem to find anyone who has had a similar problem but I think I may have found some kind of clue: While trying to run a project I made in C++/python for the Panda3d engine I kept on getting these errors:
AL lib: DoReset: Failed to initialize audio client:0x8889000f
:audio(error): alcCreateContext(_device,NULL): Invalid Device
:audio(error): OpenALAudioManager: No open device or context
I have no idea what this means as I am not very knowledgeable of computers.
it is hard to say a lot without more details, but it appears as though the computer is not detecting your audio device. Try right clicking on the computer icon in metro, and selecting manage. Go to the device manager and see if there are any devices that have a yellow exclamation point. if they do, install drivers from the vendor. If not try updating your audio drivers, and restarting.
This issue is driving me nuts. I am working on a project with some other guys who built the electronics. We have custom boards with an atmega 1284p. For USB cummunication with the 1284p we use a FTDI FT230X USB Bridge. This doesn't have DTR; RTS is used to reset the board using a capacitor (pretty much like with off the shelf arduinos).
The arduino bootloader is used, and we use mighty-1284p to upload. The board selected is "Original Mighty 1284p 8MHz". After installing the right FTDI drivers from http://www.ftdichip.com/Drivers/VCP.htm I can upload to the board from a mac. Linux has these drivers built into the kernel. However, I cannot upload to the board. AVR gives the following error:
avrdude: ser_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x00
avrdude: Send: 0 [30] [20]
dmesg gives the following:
...
[ 51.299964] usbcore: registered new interface driver ftdi_sio
[ 51.300088] ftdi_sio 1-1.2:1.0: FTDI USB Serial Device converter detected
...
and lspci:
...
Bus 001 Device 006: ID 0403:6015 Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)
...
The settings for the mac and linux machine are identical. On both I use arduino 1.0.5. Both do see the correct serial port.
I've seen many posts in this forum with similar problems, but have yet to find one with a solution that works for me. Holding reset, or clicking it just before uploading does not work. As suggested in some forums I have tried with removing brltty to no avail. I have tried uploading with the Arduino IDE, Eclipse with AVR plugin and AVR via command-line. None will work. I've tried it on different machines as well with different versions of ubuntu, and uploading works in none of them. Adding -c arduino to avrdude command doesn't do the trick either. Any ideas on how to fix this?
My user is part of the dialout group, and I can upload to other arduino boards (like duemilanove) without problems.
This question was originally asked here: http://forum.arduino.cc/index.php?topic=244363
You mentioned Ubuntu; are you doing this as a normal user?
If so, you may need to add your account to the correct group, the serial port device belongs to.
You can do that like this:
sudo usermod -a -G dialout yourself
then (easiest) logout and log back in again.
However, it is possible that it is called something other than dialout in the latest Ubuntu, I haven't checked. I can confirm it is still dialout here on Debian Wheezy.
(this is a little odd, though, if it works; usually you get a permission error instead...)
I know this is quite an old question, but in addition to the dialout group problem I've had issues with ModemManager interrogating anything that looks like a serial port (and screwing up programmers in particular because they're not expecting those bytes). I don't know if that's what's happening in your case but it's worth a shot for others who end up here.
I just removed it entirely (which is a large hammer, probably temporarily disabling it is best...):
sudo apt-get remove modemmanager
If you want to try disabling it, maybe:
sudo systemctl stop ModemManager.service
