Does anyone ever develop some application to control the spi device on OMAP3? I can load the spi driver "mcspi", but I don't know how to use it.

  • I haven't used that chip specifically, but have a lot of SPI experience. Could you narrow down the question a bit? – Judge Maygarden Dec 11 '08 at 15:44
  • Isn't information about platform missing, here? I would guess Linux from the driver name, but it's hard to be sure. – unwind May 08 '09 at 08:46

Ok So first I need to apologize for my previous shoot from the hip answer.

I too have now started looking into trying to get the McSPI's working and it has been some what painful. TI does not have lot of documentation, and I still haven;t been successful in getting any of the McSPI's to actually work, yet. But I thought I would post a link to the beagle board google discussion on the subject, as it appears they have been successful at getting at least McSPI3 working on the OMAP3530.

As of at least PSP 3.00.00.04, the mcspi driver is integrated with the Linux spi stack.

Turn on

CONFIG_SPI and CONFIG_SPI_OMAP24XX

in your kernel.

Here's how to use spi devices, in general.

There is also the spidev driver, which presents a char device to userspace, but it's experimental.
