Hello.

 

In advanced, I appreciated you reading this message.

 

I have mpc8313 SOC custom board and I developing linux device driver for spi controller.

 

As you know I referenced MPC8313erdb BSP Kernel 2.6.20 that dosen't support user-level 

 

device driver for spi controller on mpc8313 SOCs.

 

I need some advice for developing SPI devcie driver using mpc83xx_spi  platform_driver

 

finally for use user-level driver.

 

So. I found some patch for BSP kernel source spidev.c. And I patch that code to BSP kernel 2.6.20

 

Kconfig file, include header directory,Makefiel, and so on...

 

But I failed to use spid controller in user-level(open, read, write) .  I tested that device driver "spidev"

 

using test code that is writtened in /linux/Documents/spi/spi_dev that fiile's name is spidev_test.c

 

Please give a little advice for my problem.

 

It will be helps for developing user-level device driver using mpc83xx_spi platform driver that any you

 

comment.
