Can't get app_simple_AVB_demo to compile Topic is solved

[poss]

I have imported sc_avb_master from GitHub but module_avb_1722_1 will not compile with the following error:

xmake[1]: *** No rule to make target `src/aem_entity_strings.h.in', needed by `.build/generated/module_avb_1722_1/aem_descriptors.generated'. Stop.

also, sc_ethernet master (2.3.3 beta0) does not compile with its own test apps and the simple AVB demo app as there is a breaking change. What version should I be using?

A resolution to this would be greatly appreciated!

Try the lib_tsn software listed on this page instead of using the GitHub version: http://www.xmos.com/support/software/tsn

Pair lib_tsn with the software from one these application notes: https://www.xmos.com/support/appnotes/AN01032 https://www.xmos.com/support/appnotes/AN00202

Are you using an XMOS development board or a custom board?

Thanks. I will give those links a try

I am using the DSP4YOU dongle which uses the 16 core XMOS-XS1-L16A-128 chip - will that software work for this chip? It says its for xCORE-200 series device

I am using the DSP4YOU dongle

This one? http://www.dsp4you.com/products/avb-oem-series/avb-dg

I am not aware of a working example of lib_tsn with the DSP4YOU AVB-DG. You may be able to create one based off of these board support files: https://github.com/xcore/sw_avb/tree/d6 ... D4U-AVB-DG

What is your use case for the DSP4YOU dongle? If you want something that works out of the box with the latest software use one of the XMOS development boards listed here instead: http://www.xmos.com/support/software/tsn

If you must use the AVB-DG, ask DSP4YOU for the exact combination of XMOS tools version (12, 13, 14) and software (sw_avb, sc_avb, lib_tsn) that is known to work with that board.

What is your operating system and XMOS tools version?

Yep - thats the one alright.

The simple_AVB_Demo project in GitHub you pointed to has been modified by the manufacturer to work with the DSP4YOU dongle

My use case is this:

I have a digital xover/room correction unit and three way stereo speakers driven by 2 3 channel monoblocks utilising 3 Buffalo DACs each from Twisted Pear Audio.

1 dongle will provide stereo in and 6 channels out of the digital xover, and each monoblock will have an AVB listener receiving 6 channels (i.e.: stereo hi/mid/low) feeding to the 3 DACs driving the tweeter/midrange/sub in the speaker stack.

The AVB listeners should automatically connect with the corresponding talkers (I was planning on using the dongle's GUID for this)

I plan to extend this to quadrophonic so that's 6 dongles all up. The DSP4YOU dongles are only $90 each whereas the kits you referred to are considerably more expensive I believe as they have DACs built in. The DSP4YOU dongles are also very small and can be easily fitted into existing equipment

I was able to build app_simple_avb_demo.xe on Windows 7 with both tools 13.2.3 and 14.1.2 using the following instructions:

Code: Select all

git clone https://github.com/xcore/sw_avb
# modify TARGET in app_simple_avb_demo\Makefile
# TARGET = D4U-AVB-DG

git clone https://github.com/xcore/sc_i2c
git clone https://github.com/xcore/sc_util
git clone https://github.com/xcore/sc_otp

git clone https://github.com/xcore/sc_ethernet
cd sc_ethernet
# checkout sc_ethernet before mac_set_qav_bandwidth() argument change
git checkout deadcbc7e9494336890a88e140ef2e06c79b6d07
cd ../

cd sw_avb\app_simple_avb_demo
xmake
# use bin/app_simple_avb_demo.xe

Thanks - I'm trying this but when doing checkout sc_ethernet before mac_set_qav_bandwidth() argument change I get this error:

C:\Users\workspace>git checkout deadcbc7e9494336890a88e140ef2e06c79b6d07
fatal: Not a git repository (or any of the parent directories): .git

what am I doing wrong?

[ers35]

I wasn't clear enough. Do the checkout from within sc_ethernet. I edited the instructions.

[poss]

Great! It compiles!

Thank you!

I was manually downloading and importing - which wasn't working for me.

Perhaps you can also answer a couple of hopefully simple questions:

- if I disable the dongle as a talker or listener (thereby limiting it to only 8 channels one way) will I automatically get an increase from 48Khz to 96Khz - or does that require additional coding?
