ADUcM350 I2C Pins

Hi Analog,

 

Using the I2CTest example, I've set up the ADuCM350 eval board to communicate with a DAC, using the Breakout Board to access the pins and with LK1 in position B in order to access I2CSCL and I2CSDA on P4.0 and P4.1. However, I want to use P3.4 and P3.5 for the I2C bus instead. Using the PinMux software I've generated PinMux.c with the right pin-assignment for this, and switched LK1 to position A in order to access those pins on the Breakout Board. After doing this, there is no signal on the new I2C bus pins P3.4 and P3.5 and the software gets stuck in system.c line 1628 (ADI_ENTER_CRITICAL_REGION(); )

 

Do you know what the issue could be?

 

Thanks!

 

Best,

Andreas
