I have GESBC-9260S V3, i'm a little confused because i use 9260 for flashing and the 9260 manual in regards to jumper settings. Do i have the 9260S or 9260? is there i2s port? Can you provide the bootstrapper source the one from at91 not uboot? How does it differ from at91sam9260-ek?

The GESBC-9260S has only 1 SDRAM chip and uses 16 bit memory bus.  The GESBC-9260 uses 2 SDRAM chip and uses 32 bit memory bus.  The same U-boot and Linux kernel can run on both boards except the U-boot may report wrong memory size on one of the boards depending on how the memory size was defined in U-boot source code.  The bootstrap code sets up the memory controller for either 16 bit or 32 bit memory access.  The bootstrap code can not be shared between the GESBC-9260S and GESBC-9260.  The GESBC-9260 is a simplified version of AT91SAM9260-ek.  Software running on AT91SAM9260-ek can run directly on the GESBC-9260 without much modification.

Both GESBC-9260S and GESBC-9260 have I2S port on the GPIO expansion header.
