SAMD09 I2C slave

Hello, I am searching for an working example of I2C slave to run in a SAMD09. Does anyone have something to share?

I have been reading this:
https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-42116-SAM-I2C-Bus-Driver-Sercom-I2C_Application%20Note_AT03254.pdf
But when I try to compile this examples, a lot of erros are showed related to 'undefined items'. I think it is why diferent versions of ASF and/or Atmel start. (I don´t really know).
I have read a lot of webpages related to SAMDxx I2C but no one can provida a working example, neither baremetal, or asf based or atmel start based.
I beg for your help. Thanks &regards.

For your build errors of your I2C example code, you need to do some debug by yourself. For bare-mental I2C driver, you can refer to Arm CMSIS https://mcuxpresso.nxp.com/api_doc/dev/1578/group__i2c__driver...

For Linux like I2C driver, you can refer to the Linux I2C framework, which is more complex.
