Line 551 in avb_1722_1_acmp.c (module_avb_1722_1) should be changed to:

return acmp_talker_rcvd_cmd_resp.talker_unique_id < AVB_1722_1_MAX_TALKERS;

Hi there,

I'm a newbie with XMOS so please excuse my ignorance and delete my post if I'm missing the essence :-).

The latest version of app_xr_avb_lc_demo will not work properly unless you comment the following lines from avb_conf.h.
//#define MII_RX_BUFSIZE_HIGH_PRIORITY (700)
//#define MII_RX_BUFSIZE_LOW_PRIORITY (300)
//#define MII_TX_BUFSIZE_HIGH_PRIORITY (300)
//#define MII_TX_BUFSIZE_LOW_PRIORITY (200)

As far as I can see the defaults of these overrides are much higher and undersizing default buffers makes xtcp not working.

Maybe you'll take a look to this.

Thank you,
Virgil

I am connecting two daisy chain board each other without avb switch. One board is connected to linux machine (in which openavb is running).
I have two audio slice each connected to DC boards.
I want to record from 8 audio channels in which 4 channels per daisy chain board.
I want the setup like:
two DC as talkers and PC as listener.
But recorded signal does no look right form. I recorded simple 1khz sine wave.
I modified:
line 39: #define AVB_NUM_SOURCES 2
line 61: #define AVB_NUM_SINKS 2
in xmos source code.

xmos console output is as following:

I traced those messages and it is in media_clock_server.xc. There is some macros including stable threshold.
What is that threshold for? and min and max range?

What is the problem?

Thank you.

hi,

sorry if this is disturbing anybody, but we just want to make you aware of a XCore-related project: we just released Capstone, an open source disassembly framework for XCore (besides other archs such as Arm, Arm64, X86, Mips, etc).

our github is at https://github.com/aquynh/capstone, and website is at http://www.capstone-engine.org/

hopefully this is useful for XCore developers & community.

thanks.
