Hello,
the OMAP-L138 SOM-M1 has two SPI ports. I need one SPI port in my design. I do not want to use SPI1, because the system boots from SPI1 by default. I do not want to wait for the Linux System booting, until the bus can be used by the DSP.
Thus my choice is to use SPI0. The HW Spec of the SOM says, that SPI0_SIMO, SPI0_SOMI and SPI0_CLK are used for communication with the Ethernet PHY on the SOM. If I go without Ethernet PHY, is it possible to use SPI0 for own purposes, by DSP?
