xmake

I've got the XK-AUDIO-316-MC-AB board, hoping to use it as a simple 8 channel USB sound card. I am doing all of this work on a Windows 10 PC.

I'm following the guide, currently on the "Building the Firmware" step: https://www.xmos.com/documentation/XM-0 ... e-firmware.

I've worked my way through various cmake errors, editing the CMakeLists.txt a few times to sort out missing paths, and have managed to build everything correctly. (I think).
This was the

Code: Select all

cmake -G "Unix Makefiles" -B build

command.

NExt up is to run

Code: Select all

xmake -C build

but this fails. I have looked around on the forums and was pointed to this "Build Configurations" page on GitHub, which specifies I can target a specific build, but this command:

Code: Select all

xmake -C build 1AMi8o8xxxxxxx

also fails, with the same error. The output of this command is below:

Looking in the XTC /targets directory, I also can't see any "XS3-" directories or files, did my install somehow fail?

What am I missing/doing wrong here? Thank you to anyone who can help.

Think you need to be on Tools 15.3.0. Suspect you're on an older version.

Cheers,
Joe

[czabel]

Thanks for the thought Joe, but I am on 15.3.1 (just downloaded it a few days ago).

I've also tried it just now (15.3.1 downloaded today) on a Macbook and am seeing the same package error, along with a new one about a specific configuration I added to CMakeLists.txt - perhaps this isn't allowed?

Hi,

Have you used the 'SetEnv.command' script to configure the XTC tools environment? https://www.xmos.com/documentation/XM-0 ... arted.html

It configures a collection of environment variables so that the XTC tools can find things like the package files.

Cheers,
Ciaran

Progress! Thank you for holding my hand, I should've read beyond 'Install the Tools.' :s

So now I've built the firmwares (including the one I added), but they don't behave as expected as devices.

First, I added a configuration to the CMakeLists.txt file:

Code: Select all

set(APP_COMPILER_FLAGS_1AMi8o8xxxxxx ${SW_USB_AUDIO_FLAGS} -DAUDIO_CLASS=1)

And it appears to have worked, I at least have an .xe file that matches that name, and the

Code: Select all

xmake -C build

command gave me no errors. I then flash it using

Code: Select all

xflash path/name/here.xe

and that also appears to succeed. However, when I go to configure the channels, it only enumerates as a two channel device, despite the 8 channel count that I thought I assigned. Did I do something wrong here? Is UAC1 just hard limited to stereo? I'm finding it very frustrating to try and answer that question via searching the web...
See the below screenshot for the Windows interface that *should* allow you to set multichannel configurations, if available:

uac1_channelConfig.png

Second issue is regarding the 'standard' set of firmwares that already existed in the CMakeLists.txt file. Specifically: 2AMi8o8xxxxxx and 2SMi8o8xxxxxx. Both built and flashed successfully, and the device enumerates as a UAC2.0 device, but I get even less functionality:

uac2_channelConfig.png

Realistically, if someone were to make a UAC1.0 flavor that had 8 channels out, I'd be sorted. I don't plan to do any real 'development' work on this platform, I was just hoping to use this as a high quality multichannel sound card.
