Raspberry Pi B+ "Illegal instruction" #2

Closed dseven closed 7 years ago

dseven commented 7 years ago

Should the v0.1.2 ARM build run on a Raspberry Pi B+ ? I get:

You are trying to execute a 32-bit Intel binary on tour Raspberry Pi, that won't work

dh1tw commented 7 years ago

@tehmaze is correct. Please download and use the ARM binary from the release page. If you then still have problems, feel free to open another issue!

dseven commented 7 years ago

I guess neither of you read the output of the "file" command ... or I'm losing it....

dh1tw commented 7 years ago

Right - sorry. In principal it should work. I compiled the binary on a Raspberry Pi 3. Did you compile the binary (if - which version of Go did you use) or did you download the compiled binary?

dseven commented 7 years ago

I downloaded https://github.com/dh1tw/remoteAudio/releases/download/v0.1.2/remoteAudio-v0.1.2-linux-arm.tgz . I suspect that the Raspberry Pi 3 uses a newer version of the ARM instruction set, and the binaries may be incompatible. I'll try to find time to get a development environment together. I did get the x86_64 build to work between a couple of boxes running Fedora at home, but not sure I want to dedicate either of them to the "hilltop end" for a real remote trial - the Pi is not doing anything, so it'd be nice if that could be made to work..

dh1tw commented 7 years ago

I know that Go 1.9 will drop support for older ARM Platforms, but it could indeed be possible that there have been changes in the ARM instruction sets between Raspi (Model B) and Raspi 3. I unfortunately don't have an Raspberry Pi 1 anymore in order to give it a try. But it should be possible to get remoteAudio compiled on the Raspi 1 - at least with Go 1.7 / 1.8rc.

Please let me know if you need assistance during the build process!

dseven commented 7 years ago

I got go 1.7.5 installed on the Pi, but hit a wall trying to build protobuf - it's failing when trying to link libprotobuf.so with no useful error message - only "ld returned 1 exit status". It's starting to feel like more trouble than it's worth. Maybe I'll find more enthusiasm another day.... UPDATE: looks like I ran out of "disk" space. Will probably have to start over with a larger SD card (another day).

dseven commented 7 years ago

Well, I got it to build (protobuf took hours). Now to get it to open an input device ....

dseven commented 7 years ago

Got it sortof working (by not trying to specify the input device) ... but showing high latency on the client (which is the x86_64 box that was working well in previous test, on the same LAN) - 200-400ms, getting jitter, and lots of "InputOverflow" reports on the (Pi) server. Maybe the Pi 1 is not up to the task :/

dh1tw commented 7 years ago

Hey, all the alsa warnings you see are not critical. If you want to remove them you have to remove or uncomment them in /usr/share/alsa/alsa.conf. If no input/output sound device is specified to remoteAudio, then the default card will be used. In your case it seems to point to the built-in bcm2835.

You can explicitly set the default soundcard by adding $HOME/.asoundrc

pcm.!default {
        type hw
        card 1
        device 0
}

ctl.!default {
        type hw
        card 1
        device 0
}

This requires a reload of Alsa or a simple restart of the Raspberry Pi.

Have you checked the CPU usage on the PI with something like htop or top ?

With which version of Go did you compile remoteAudio? 1.7 or 1.8rc ?

OutputOverflows mean that portaudio/alsa was not able to write the data in time to the sound card. This might be an issue of not enough CPU power available. That could also be the reason for the extremely high latency. I have on a local network a latency of 1ms with a Raspi 3.

Have you tried to increase the rx buffer size?
