Hi,

 

I have the u-boot code of mcf54455evb.now I am designing a new board with processor of mcf54452.

 

When I make the changes in the u-boot code for configuring SPI, i am getting errors like this

undefined reference to `spi_init_f'
undefined reference to `spi_init_r'

(in the file ~/board.c)

undefined reference to `spi_read'
undefined reference to `spi_write'
undefined reference to `spi_init_f'

(in the file ~/cmd_eeprom.c)

 

I am following the README file. i have done the modification for SPI configuration what they mentioned in the read me file.

Even though the two C files have inludes to an .h file (common.h) that define these functions...Any ideas what is happening here? The thing is, the only place I can see that these functions are given are in a file called spi.c, which exists in *some* board config folders. Does this mean that i need an spi.c file added into the /board/mcf54455evb/ folder? I have to write the definitions for those function?

 

Thanks & Regards,

Karthik
