The TWI1 pull-up charge is excessive.
The pull-up charge on TWI1 data and clock lines is a bit too high and out of I²C specification.
Workaround:
Although the board proves to be functional as is, we recommend to fix this excessive pull-up charge by removing
resistors R178 and R179. These are located near the J17 connector and the Atmel logo, as shown in the following
figure:
Figure 5-1.
Position of R178 and R179
