ChibiOS I2C OMNIBUS F7V2

Hi,

By default, the compass that comes with GPS is not detected (but it is on omnibus F4 pro for ex).
To get the compass detected or other devices, pull up must be added.

I was wondering if there are any difference between :

  • adding 2 pull up resistors
  • adding PULLUP on the hwdef.dat file
# optional I2C device2, shared with USART3
PB10 I2C2_SCL I2C2 PULLUP
PB11 I2C2_SDA I2C2 PULLUP

This is the case for some other board like omnibus F4 pro. Any reason for not adding it to the Omnibus F7v2 ?
