VoCoreV2 and respeaker mic array

Mon Mar 02, 2020 12:21 pm

I want to hook a VoCoreV2 to this mic : https://www.seeedstudio.com/ReSpeaker-U ... -4247.html

The idea is to use that as a sip client or webrtc chat. Either will do.

Can I simply connect the mic array to USB TTL part ?

Thanks for your info

I checked that is a USB mic array, so you can directly connect it to VoCore2 USB 2.0 host interface, and in firmware add USB sound driver. Then it should create some device at /dev/.
rtc and sip is software, same as Linux computer.

I have now tried installing the Respeaker USB audio mic but it seems it is not detected by the vocore device.

I get this :
root@OpenWrt:~# opkg list-installed | grep usb
kmod-usb-acm - 4.14.131-1
kmod-usb-audio - 4.14.131-1
kmod-usb-core - 4.14.131-1
kmod-usb-ehci - 4.14.131-1
kmod-usb-hid - 4.14.131-1
kmod-usb-ohci - 4.14.131-1
kmod-usb-serial - 4.14.131-1
kmod-usb-storage - 4.14.131-1
kmod-usb2 - 4.14.131-1

usbutils - 007-9
root@OpenWrt:~# opkg install kmod-sound-core
Package kmod-sound-core (4.14.131-1) installed in root is up to date.

root@OpenWrt:~# alsactl init
Found hardware: "soundcard" "" "" "" ""

root@OpenWrt:~# lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It seems I need to make menuconfig to add usb-audio support, but I do not know how to do that in vocore device.

Thanks for your help.

I do not think it is driver issue, even no driver, lsusb will show the device. Looks like the USB host is broken or the USB device is broken.
1. use USB disk to check if VoCore2 USB Host is broken.
2. connect your USB device to computer, use lsusb, check if the device can be detected.

Thanks, you put me on track, I checked and my cable was only power not data.

Changed it and now I can see the device, even though is does not work yet ....

Will keep you updated
