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
