Device Tree • Re: i2c overlays are not exposing 0,2,3 Pi5

Code:

...[all]dtoverlay=spi0-0cs,i2c1-pi5,i2c0-pi5,uart1-pi5dtparam=uart0=on...
As rpdom said above, these are all separate overlays and need to be on separate lines for each overlay.

Code:

...[all]dtoverlay=spi0-0csdtoverlay=i2c1-pi5dtoverlay=i2c0-pi5dtoverlay=uart1-pi5dtparam=uart0=on...
That does not work

Code:

fred@pi5:~ $ ls /dev/i2c-*/dev/i2c-1  /dev/i2c-11  /dev/i2c-12fred@pi5:~ $ 

Code:
