I have a problem to get working serial port under dietpi
When I will use a dietpi-config and switch on ttyS1
but it doesn’t work
ttyS1 I found in the wiki
odroid-n2:application_note:gpio:uart [ODROID Wiki]
what’s wrong and how to get working ?
Wire conection according to wiki
ok, solved
wiki is wrong. It’s ttyAML1
Jep, legacy kernel uses ttyS1, mainline kernel uses ttyAML1.
Sorry, back with my problem. I did a upgrade of the dietpi
now I have :6.1.11-meson64
Before a had working ebus communication via my adapter connected to dev/ttyAML1
But after upgrade ttyAML1 no longer exist and communication not working
Really don’t know how to solve now
Thanks for each help
