SPI to Atmel AT45DB161 flash

In the past , I have done a bit-bashed SPI to atmel flash AT45DB161,
since I could never get the 908GP32's hardware SPI to work with this part.
I think there is a compatibility problem with the way the flash expects the leading bit to be clocked out.
Has anyone implemented the 908's  SPI to the AT45DB161 ?

Hello,
 
According to the datasheet for the serial flash device, the data transfer should be compatible with either of the conditions CPOL = 0, CPHA = 0, or alternatively CPOL = 1, CPHA = 1.  I assume that you are operating both devices from the same Vdd supply of 3 volts.
 
Perhaps you might post the SPI communications code you are using, and provide more detail on the nature of the problem you are experiencing.
 
Regards,
Mac

No, but I've interfaced an S908JM60 to an Atmel 25FS010 Flash part without any problems (hopefully), using the built in SPI and interrupts.
