Description
I2C is not working using PA08 and PA09 on the ATSAMD21G18A-AU with an Arduino Zero bootloader on a custom PCB.
-Tried Modified I2C Scanner
-Normal I2C on PA22 and PA23 still work

Research direction
Reproduce the I2C failure on PA08 and PA09 with the modified I2C scanner, then compare it with the working PA22 and PA23 configuration on the custom ATSAMD21G18A-AU board. Inspect the ArduinoCore-samd pin and SERCOM handling relevant to these pins; done means I2C operates on PA08 and PA09 as well.
