Check thoroughly the impedance matching and trace lengths on the “special” signals listed in 
Table6. 

 

Select the right output strength in the DTB file of your BSP and avoid using excessive strength for 
signals that don’t need this. Also, consider carefully the FAST output mode, as this leads to EMI 
problems and ring on not well-matched traces. 

 

The I2C lines (I2C2_SCL,

 

I2C2_SDA) has a 3.3KΩ pull ups on the 

NOVA

som

 M7Plus board to their 

own power. Avoid to place additional pull ups on the I2C lines, as this may lead to malfunctioning 
due to excessive load. 

With these simple hints you will successfully design your own Extension board.
