One Wire GPIO

I’m trying to make temperature readings thru the one wire protocol with a DS1820.

I’ve had sucess with doing thru the FIM side. but i would like to make it work thru the GPIO side in order to free the FIM to i2C work.

I’ve followed the instructions on the manual, but no luck, as if gives me a compilation error on the cme9210js.c.

It says ns921x_fim0_w1 is first time used, and not registred.

I’m using a CME 9210 with linux 5.2

As anyone got this to work?
