We do need usb host mode, i2c and ethernet operation at the same time. As I understood, i can't load the microcode patches for usb sof generation and iic/spi together, because they "live" at the same address. Now my question: What occurs if I don't load the ii2/spi patch. I do need the usb sof timing, but does the i2c-Interface work without the iic/spi patch ? As I read on the motorola webserver, the iic/spi is needed for concurrent operation of scc ethernet and i2c. Does i2c work correctly without the patch if I don't use ethernet ?
