Hello, I am trying to use spidev to send messages via spi on OMAP-L137 EVM board. I have an spidev entry in /dev, but when I try to send data, I have the following message:
spidev spi1.0: SPI transfer failed: -22 spi_master spi1: failed to transfer one message from queue Debugging using printk, I found out that a probe function is called, and after this transfer_one_message is called. In transfer_one_message master->transfer_one() function is called and returned with the error. But I can't find the implementation of transfer_one function for davinci_spi. So, I have two questions: What implementation is used by default when transfer_one implementation isn't provided? Should I write my own implementation of transfer_one function& -- Regards, Denis Obrezkov
