Thanks for taking the time to bring this driver so far along. I'm getting a failure after compiling and loading the dtb:

git clone https://github.com/cdumonde/raspberry_slave_i2c.git cd raspberry_slace_i2c make dtc -@ -I dts -O dtb -o i2cslave-bcm2708-overlay.dtbo i2cslave-bcm2708-overlay.dts sudo dtoverlay i2cslave-bcm2708-overlay.dtbo sudo insmod bcm2835_slave_mod.ko dmesg | tail ... [169115.045032] 3f214000.i2c [169115.047702] bcm2835_i2c_slave 3f214000.i2c: alias is missing [169115.054095] bcm2835_i2c_slave: probe of 3f214000.i2c failed with error -22

I tried substituting the 0x7e2XXXXX entries with 0x3f2XXXXX, but that wasn't the issue.

Do you have any thoughts on what might be the issue?

Thanks again, Hunter

Most of those adresses are given by the main dtc file. It seems to have change since a couple of version. Unfortunately I don't have a pi close to me and I'll be only able to help next week. This driver was working out of the box for pi2 + and a 8month old raspbian
