Freeplay CM4
#49
Unfortunately, I don't think my board's manufacturer soldered anything but GPIO0 and GPIO1 from the CM4 to the adapter board. So it would have to be GPIO0 and GPIO1 Sad

I verified that /etc/modules does include `i2c-dev`.

I tried adding `dtoverlay=i2c6,pins_0_1` to the config file. Now I see GPIO0 and GPIO1 correctly set as data and clock when running `raspi-gpio get`:
Code:
pi@retropie:~ $ raspi-gpio get

But I still don't see anything when probing i2c6 (It was really slow when returning each address space)
Code:
pi@retropie:~ $ sudo i2cdetect 6
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-6.
I will probe address range 0x03-0x77.

Running `raspi-gpio set 0-1 ip pn` removes GPIO0 and GPIO1 from being receiving I2C data:

But still no devices registered in i2c6.

Nothing else is showing sda and scl with `raspi-gpio get` but still ran the suggested commands to make sure without much luck:
Code:
pi@retropie:~ $ raspi-gpio set 44-45 ip pn
pi@retropie:~ $ raspi-gpio set 2-3 ip pn
pi@retropie:~ $ raspi-gpio set 0-1 a0
pi@retropie:~ $ i2cdetect -y 0

I did solder GPIO44 to pin3 and GPIO45 to pin 5 but everything seem to point at something being wrong in my wiring, right?
