Using both SPI and serial driver on ConnectEM

I have been having trouble getting both SPI and serial to work on the connectEM. We hope to use SPI on port 1 and serial on port 2. bsp.h is set up such that the spi driver is configured for port 1 and 2-wire serial for port 2.

Under this configuration, we are unable to open /com/1 (port 2) for serial communication.

Does anybody have experience in this?
