How to build and run video codec sample application?

Dear sifive team,
I can see WAVE521/WAVE511 SDK here:

But there is no firmware, is it missed?
The same for WAVE511.

Thanks,
Kun

Maybe this post can give you some help.

Hi Julie,
Thanks a lot for your quick feedback!
What about the firmware for WAVE521 encoder?

BR,
Kun

I’ve seen firmware:

wave511_dec_fw.bin
wave521_enc_fw.bin
wave521c_codec_fw.bin
From a link I posted here.

But I have no idea if they are the right firmware.

Hi mzs,
Thanks a lot for your info!

BR,
Kun

Hi SiFive team,
I test with wave521/wave511 sample example, but fail.
Please see the following logs:

module=“venc”
device=“venc”
mode=“664”

Group: since distributions do it differently, look for wheel or use staff

if grep ‘^staff:’ /etc/group > /dev/null; then
group=“staff”
else
group=“wheel”
fi

invoke insmod with all arguments we got

and use a pathname, as newer modutils do not look in . by default

/sbin/insmod ./$module.ko $* || exit -1

major=cat /proc/devices | grep $device|awk {'print $1'}

Remove stale nodes and replace them, then give gid and perms

Usually the script is shorter, it is simple that has several devices in it.

rm -f /dev/${device}
mknod /dev/${device} c $major 0
chgrp $group /dev/${device}
chmod $mode /dev/${device}
