For the interested: I found that MAC can also be obtained on a more lower level: hexdump -s 4 -n 6 /dev/mtd2 | sed -n '1p' | awk '{print substr($2,3) substr($2,1,2) substr($3,3) substr($3,1,2) substr($4,3) substr($4,1,2)}' as seen in the ethernet-mode init.d script

Thanks @György-Farkas and @crispyoz for the confirmation. I have seen the 2S reference but just wanted to make sure before I spin out a PCB as there is a discrepancy with the 2/+.

Thanks will certainly consider the chip option. I'll also try and copy the trace antenna from the dev board image as best as possible and compare results.

Hi, I have configured the I2S as it is shown in this topic and the I2S Output work perfectly. Now, I'm testing the I2S Input and I've found some problems. I'm trying a loopback between I2S_DOUT and I2S_DIN to test the I2S input. When I try to use the arecord command there is an error: arecord: main:828: audio open error: No such file or directory Could you indicate how did you test the I2S input? Thank you PD: here are the output of the arecord -l and arecord -L: root@OpenWrt:/# arecord -l **** List of CAPTURE Hardware Devices **** card 0: AudioI2S [Audio-I2S], device 1: ralink-i2s-dir-hifi dir-hifi-1 [ralink-i2s-dir-hifi dir-hifi-1] Subdevices: 1/1 Subdevice #0: subdevice #0 root@OpenWrt:/# arecord -L null Discard all samples (playback) or generate zero samples (capture)

Yes, your post is quite helpfull. I find it strange that Onion dont tag it accordingly, but hey guess they have to leave some work for us. Regards, UFD

@cas , Thanks for your assistance. After playing around for a bit, I ended up removing postfix from the compilation process in the .config file. It was set to module, so hoping that it is not that important. Regards, UFD

This topic seems to be making a lot of leeway with i2s audio. Is the actual hardware i2s driver the ralink-i2s driver? If so, I'd like to try to add support for the Audioinjector Stereo soundcard.

Pi Zero W is a loss leader. That part can someday disappear. I agree spec wise its better but Onion is much better when handling network tasks IMO. Dual WiFi, 5 Ethernet Ports, etc. It's also PCB board solderable. If the Pi Zero W was PCB board solderable I would of went with that part.

Thanks @Maximilian-Gerhardt I just changed "br-wlan" to "ra0" as this interface has a MAC value consistent with the sticker.

@György-Farkas said in I2C Detect Slave Method?: ./busybox-mipsel devmem 0x10000940 32 0x8064800F I am very grateful to you, it worked fine ...

In case anyone stumbled upon this issue or something related to this. Since I do not have a linux machine, I decided to spin up a cheap 1cpu, 512MB ram, $5 digital ocean droplet to setup my toolchain and compile some code for the onion. The above issue occurred on a fresh ubuntu 16 and ubuntu 17 droplet. A friend did some googling and pointed out that these type of issues could be memory related and he was spot on. After setting up 2GB swap space using this guide: Adding Space on Ubuntu the compile has completed successfully on both Ubuntu 16 and 17. Hope this helps someone experiencing this frustration. Cheers.

Just to help others out look here for the bitbanged approach that @UFD created https://community.onion.io/topic/2312/i2c-detect-slave-method
