Support Question

[Amit kumar]

Dear Experts,

I am using SBC 9260 for development of a data acquisition platform. I am
using the SPI for data acquisition through 14 bit ADC slave. Currently
my board has debian 5.0 kernel version 2.6.30. I am using the spidriver
(spidev )for using the SPI on the board in master mode . Everything is
working fine and I am able to send and receive data . The only problem
is between the activation and deactivation of chip select.It takes
around 70microseconds for chipselect deactivation and then activation .
Since speed of my 4 channel ADC is 1MSPS so i need to bring down delay
as minimum as possible. I checked out the value of the registers
DLYBCS , DLYBCT , DLYBS and all are indicating the values 0.

Therefore I don;t have any idea from where the delay is being
introduced. Is it a problem of OS or there is nythng else involved .
Kindly guide me through this . I need urgent help .... any information
abt delay is welcome.

regards
amit
