Hi!

I am using imx28 Evk board (TQMa28  SOM with MBa28 STK ) with Linux 2.6.35 Kernel

I am able to used ssp2 & creating /dev/spidev1.0

But I am not able to creating /dev/spidev2.0 for SSP3

How can we use SSP3? How to create device file /dev/spidev2.0 for SSP3?

Thanks in advance!

Assuming the original L2.6.35 FSL Linux BSP, you first have to appropriately configure the IOMUX module to enable SSP3 functionality on the AUART4 pins. For more information on the IOMUX driver, please refer to the Section 3.4 of attached i.MX28 EVK Linux Reference Manual document.

Then, you have to add the SPI driver for the SSP3 interface. For more information, refer to the Chapter 21 of attached document.

The TQMa28 Support Wiki also would be helpful:

Have a great day,

Have you disabled the AUART4 driver? If not, it may cause the pin conflict.
