On many CPU pins, you can select pin function between GPIO and one or more special functions. Please refert to chapter 9 "I/O PORTS" in the datasheet. This is what it would help: If you want hardware SPI on the debug connector, you could switch the ACCEL_SPI pins to GPIO function and enable SPI function on the DEBUG_SPI pins instead. So no conflicts. -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year _______________________________________________ gta02-core mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/gta02-core
