bananapi m1 i2c problems
by brian-in-ohio from LinuxQuestions.org on (#6R3ZV)
I have a banana pi m1 running 15.0. When I use (as root) i2cdetect -l it gives no output, lsmod gives this output:
i2c_mv64xxx 20480 0
To verify its not a hardware issue, I used a fresh armbian install where upon i2cdetect -l showed the i2c-mv64xxx kernel module for both i2c busses. I verified, under armbian, that i2cdetect 1 -y would find an i2c device by pluging in an lcdbackpack, it found it no problem.
I then tried loading the i2c-mv64xxx using the /boot/local/load_kernel_modules.post adding a modprobe line:
modprobe i2c-mv64xxx
That did not work. So I'm at the end of my limited knowledge and I couldn't get any help from early forum posts. Is there any help out there, or do I have to switch to armbian for this old banana pi to use i2c?
Thanks
