Initializing SPI pins using code

If you gumstix overo spi to use SPI bus 1 off the Overo expansion board, then you need to completely disable one or both of these kernel modules in your kernel config and rebuild your kernel. Different boards may bring out different SPI bus pins.

Many of the pins of an OMAP3 system can be multiplexed for different functions. You can do your muxing in either place, but since the kernel follows the bootloader, values set in the kernel will override. Here are some instructions for modifying the pin muxing in u-boot - Gumstix u-boot development The values currently gumstix overo spi in the Overo u-boot overo. IEN still allows output.


If you wanted to do the pin mux'ing in the kernel, you would do it in board-overo. Add to Compare. What's Included.
