hi,

 

I use the chip bf561。 uclinux:2010R5

 

bf561 only one SPI interface .

In hardware design,SPI connected SD card and ad7466.
AD7466 is used to adjust the volume .


When I mount the SD card after reading through the spi AD7466.

SPI data read is error.
This time I saw   SPI Flag register is 0xFFA0.
chip select 5 is AD7466,
chip select 7 is SD card .

 

When mounted on the SD card later , spi bus, the possibility to access their equipment ?

 

thank you.
