I am using am3358 to design the product.

  I have write a fpga driver and test it in the SD card.but when i flashing all the program in the nand(MLO u-boot.img uImga ubi.img fpga.ko).

when the linux is work
Please help me to work out this question, thanks.

We can not help with problems related to linux that you run on TI evaluation board.

What is fpga.ko ?? We have no products with sitara, how did you make the connection from sitara to our FPGA module?
You made sd card boot image for? For TE0720 or some other our SoM or for sitara?
