SPI 1 ON DM355

Hi Kevin,

In Linux 2.6.10, there is no support for /dev/spi interface. In this case, the SPI just acts as a bus and the device interface  (in /dev) is exposed by the slave devices (like EEPROM in drivers/mtd/devices/at25xxA_eeprom.c).

Support for /dev/spi (aka spidev) is present in later kernels (community Linux).

Thanks,

Sekhar

Hi Sekhar,

                If  I want to connect a touchscreen chip (ADS7846) to SPI1, how to do?

Thank you!

Hi  Sekhar,

           What is the EEPROM in drivers/mtd/devices/at25xxA_eeprom.c    used for (this eeprom connected with SPI0 on DM355 EVM)?  

It seems that system can't start when I disable this EEPROM in kernel.

Thank you!

Kevin
