I’m using an Overo Fire with a Tobi attached. I’ve got SPIDEV enabled and the two touch screens disabled. I have both SPI1.0 and SPI1.1 in /dev by modifying board-overo.c. Both are running in SPI mode 3 at 0.5MHz.
The SPI_CLK line works fine, as do SPI1_CS0 and SPI1_CS1 in either unidirectional or bidirectional modes.
Unfortunately, I have a 50Hz output on the MISO line from the Tobi, and my MOSI doesn’t work (line stays high and doesn’t output the data sent to the device buffer.
Can anyone help me out?
