The pins for uP_nOE, uP_nWe and uP_nCS1 are part of the GPMC. The most detailed information about the GPMC is found in TI's DM3730 Techincal Reference Manual (http://www.ti.com/lit/pdf/sprugn4) and that includes the various memory addresses for accessing it.

If your project is only going to use a few IO lines as GPIO, we have AN527 which describes how to use individual GPIO pins. http://support.logicpd.co...rtalid=0&EntryId=698

Without knowing anything about your FPGA or schematic, it's difficult to offer much assistance, but we do offer both a support contract (http://support.logicpd.co...upportPackages.aspx) where we could offer schematic reviews and offer suggestions on how to best wire it electrically.

If you wanted software help in writing the drivers, we also have a services contract (http://www.logicpd.com/se...oduct-development/).

If you are interested, I can have someone from sales contact you.

Can I adress to GPMC ? Give me ,please , example ! Thanx beforehand !

Unfortunately, we don't have any template examples, but the SMSC LAN9221 controller and the ST Ericsson ISP1763A USB controller both use the GPMC bus.

You should be able to look at those drivers to see how they interact with the GPMC bus. Just make sure you use a different chip select to avoid contentions.

Can I use DCLK (GPIO_8),DATAO (GPIO_130) ,NCONFIG(GPIO_131),GetNStatus (GPIO_134) I found some functions in gpio.cpp . Is it true ?

I don't fully understand what you are application is, but there is a difference between the GPIO and GPMC. If you want to just manually control individual GPIO pins, I would suggest you look at our App Note on Selecting and Using GPIO signals. http://support.logicpd.co...rtalid=0&EntryId=698

Each GPIO pin shares functions with peripherals, so if you choose to use a certain pin as GPIO, the associate peripheral may cease to function. Our schematics found on http://support.logicpd.co...M3703TorpedoSOM.aspx under the

If you are planning on using the GPMC bus which it seemed like you wanted to use, you'll have to use the pins that are associated to the bus.

My suggestion would be to setup a support contract where we could look at your schematic and a block diagram of how your FPGA interfaces to the SOM, and we could make suggestions on how to connect it: http://support.logicpd.co...SupportPackages.aspx
