we are design new uclinux  based bf537 board.


currently we are in half of sea.


The problem is started now,




we are using adv7393 video encoder.



We have referred the Analog Devices ADV7393 EZ Extension card for our

design. The following changes have been made in the our design.


         * 8 bit data input i.e., SD , YCrCb format. Where as in Extension

card its 16 bit data input.







         * The PPICLK provided to blackfin537 is 27MHz whereas in Extensioncard it is 13.5 MHz.


The upper 8bit (P8 to p15) are connect to blackfin PG0-gpio/ppi D0 tp PG7 gpio/PPI D7 pins.

I changed the 8 bit input format and the PPI-clk(PPL clock disabled)in bfin_adv7393fb device driver.

I am not getting any output on Tv.

Whether the test pattern will work for our design.

if its work,then how do test
