Error! Bad return status for module build on kernel: 4.19.42+ (armv6l)

[VinQbator]

Just got the AIY-vision kit and it worked fine at first. For some reason I did apt update and apt upgrade and after that it has been a long day of debugging, but nothing helps.

When trying to run any vision scripts I'm getting

File "/home/pi/AIY-projects-python/src/aiy/_drivers/_spicomm.py", line 219, in __init__
    self._dev = os.open(SPICOMM_DEV, os.O_RDWR)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/vision_spicomm'

I've uninstalled all aiy-* packages and reinstalled according to HACKING.md but still the same issue.

I think the kernel upgrade messed up the system. Is there any other way besides flashing the SD card?

When trying to install aiy-vision-dkms, I'm getting the following error.

I too cannot get vision bonnet to work on RPI strech lite (updated os and kernel, rpi zero) I believe HACKING.md needs refactoring

regarding your specific issue, you can build aiy-vision-dkms if you run: sudo apt-get --purge remove linux-headers-3.6-trunk-common

-> according to: https://stackoverflow.com/questions/54450251/build-of-aiy-vision-dkms-fails

personally I've tried and successfully built aiy-vision-dkms, yet still cannot get "Myriad ready" in dmesg

[TheSwert]

I had a similar issue with my Voice kit. I found a script that will revert the kernel to 4.14.98 (last version I had installed that worked). After reverting the kernel version and rebooting you should be able to either do a dpkg-reconfigure on the installed modules, or just reinstall them.

[tarzanek]

after rpi kernel upgrade just rebuild of dkms packages is enough for me to get AIY back working (see workaround in https://github.com/google/aiyprojects-raspbian/issues/570 )

scratch that, I see the same issue with newest kernel (error: implicit declarat ion of function ‘i2c_lock_adapter’ [-Werror=implicit-function-declaration]) , I have a bad feeling the code for drivers needs upgrade ... @dmitriykovalev help, please?

[itsalljustaride]

This project is in real need of a new disk image with updated kernel, etc. It has been nearly 8 months since the last working disk image release. Is the AIY project dead?

[tarzanek]

had a quick look and the patches are not that hard to do basically for /var/lib/dkms/aiy/1.1/ apply https://github.com/raspberrypi/linux/commit/97623c0a80a605ef3fae337081ed008796bf8cc2#diff-3ec871a8e75c9ea85161805bbdee22a1 and https://github.com/raspberrypi/linux/commit/3f3a89e1d7c31558c070692241e3d6146d2cf1bf

the harder part is to update google deb repos for everybody to get the fixes

[ginkage]

I got it working with kernel 4.19.57.

There are two files you'll need to edit (note that you'll need to use sudo to edit them). First one: /usr/src/aiy-1.1/aiy/iio/adc/aiy-adc.c (note that /usr/src/aiy-1.1 is where the source code is copied from when the module is being built).

Remove this line: .driver_module = THIS_MODULE, (line 138, I presume).

Second one: /usr/src/aiy-1.1/aiy/mfd/aiy-io-i2c.c

Replace two occurrences (in aiy_io_reset and in aiy_io_update_firmware) of i2c_lock_adapter(i2c->adapter); with i2c_lock_bus(i2c->adapter, I2C_LOCK_ROOT_ADAPTER);

and replace two occurrences of i2c_unlock_adapter(i2c->adapter); with i2c_unlock_bus(i2c->adapter, I2C_LOCK_ROOT_ADAPTER);

Then run the following command: sudo dkms install aiy/1.1

Reboot, and Bob's your uncle. Literally five lines of code to change. :)

[tarzanek]

@ginkage will you be able to update deb packages too? ;-) Or know someone who can patch them and build and upload to googles repo?

[CEBasile]

I have updated and rebuilt the package. You can get it here: https://drive.google.com/open?id=1s6ru6Clz0pmX0VS3BOW9XJoqKE7E8y12

@CEBasile where is the source code all of the AIY debian packages? It's not in this project, right?

If it were here we could submit a pull request with the fix.

[CEBasile]

@HeatfanJohn This is just the python framework. The drivers are another repo. Look at HACKING.md

[HeatfanJohn]

@CEBasile I see the reference to add the AIY vision package repo and I downloaded https://dl.google.com/aiyprojects/deb/dists/stable/Release to see the Debian release information:

And then downloaded the package information https://dl.google.com/aiyprojects/deb/dists/stable/main/binary-armhf/Packages

But that only shows the deb locations. Where / how do you find the source code? Or is the source code included in the deb files?

Update:

The deb files do contain the source. I guess that you downloaded the deb file in question, unpacked it, updated the source and re-packaged the deb with the update.

Why doesn't Google just put the deb source on Github?

no go there

[CEBasile]

Just wanted to let everyone know that downgrading to kernel 4.7 fixes these issues. Currently working on fixing this for kernel 4.19.66
