Hello,
I have a BPI-Berry board. How can I set I2S under Ubuntu ?
hello，what do you mean to set I2S under Ubuntu？
it’s easy to set by sound & video software in GUI.
Hello @Jackseng,
I wish to plug these audio cards on my M2 berry :
I have already done on my Odroid C1+ and on my OrangePi PC+ like described here :
- https://forum.odroid.com/viewtopic.php?f=118&t=15741
- https://forum.armbian.com/topic/759-i2s-on-orange-pi-h3/
I have installed Ubuntu-server, not Ubuntu Mate and as soon as I’ll get help about i2s, i shall add MPD server
V40 soc has I2S but what pins on GPIO are using ?
I have found the pinouts on the GPIO socket to connect an audio card in the 3rd sheet untitled “CPU2” on the top left side of the GPIOB/H/I of the BPI-M2 BERRY specifications.
But these pinouts are 2 or 3 functions. So I think the u-boot must be setup to select the right function like th M1+ as explained here : http://forum.lemaker.org/forum.php?mod=viewthread&tid=11807&extra=&page=2 on the post #14.
I don’t know how to do the same task on the M2-berry with Ubuntu-server.
Hello，I have checked the M2-berry 40pin gpio definition don’t have I2S interface，but if you want to use I2S，you could try M2m.
No, you are wrong !
Look at :
- BPI-M2 Ultra hardware specification
- Schematic diagram on the third sheet as I said
- page 698 and follows of the V40 datasheet
Can Sinovoip give us a howto or some BPI-tool to set I2S or we are waiting for Armbian make the job ?
Sinovoip say that GPIO supports I2S but nothing runs !
Hello, I know what you said, soc supports I2S， but 40pin GPIO don’t have I2S pins
As you can see，all the I2S pins are used to other functions
