visionkit: bonnet boot failed -113

[webrtchacks]

I purchased the Vision Kit yesterday on a new Pi Zero W, but I cannot get to to work. It seems the Myriad chip is not loading:

journalctl shows the following on my first boot after loading the image:

Code: Select all

pi@raspberrypi:~ $ journalctl | grep visionbonnet

Dec 18 10:36:46 raspberrypi kernel: googlevisionbonnet spi0.0: Inital bonnet boot failed: -113
Dec 18 10:36:46 raspberrypi kernel: googlevisionbonnet: probe of spi0.0 failed with error -113

I am able to get the camera to work if I connect it directly to the Pi Zero W and ~/AIY-projects-python/src/example/buzzer_demo.py works fine too.

I also tried enabling the SPI through raspi-config and /boot/config.txt with no success.

What does error -113 mean? Are there any diagnostics I can do?

Your the first person with a Vision Kit to post in this forum.
Whilst someone might come along with help - can I suggest that if you followed this guidance https://aiyprojects.withgoogle.com/vision/ you raise the issue with google by posting a new issue at the following url https://github.com/google/aiyprojects-raspbian/issues

Thanks. I posted the issue here for reference: https://github.com/google/aiyprojects-r ... issues/217

Hi, I've just updated your issue.

May be worth un commenting some of the lines in the /boot/config.txt specifically

# dtoverlay=googlevisionbonnet-myriad
# dtoverlay=aiy-io
# dtoverlay=aiy-leds
# dtoverlay=dwc2

Best to un comment them one at a time and reboot

i have mine working and my /boot/config.txt has the follwoing commented.

Code: Select all

# Enable audio (loads snd_bcm2835)
#dtparam=audio=on
# dtoverlay=i2s-mmap
# dtoverlay=googlevoicehat-soundcard
# dtoverlay=googlevisionbonnet-myriad
# dtoverlay=aiy-io
# dtoverlay=aiy-leds

also something for you to compare against hope this helps.

Code: Select all

Turned out to be a pin header problem. Now resolved
