Linux drivers for SDRAM for AM1705

Other Parts Discussed in Thread: AM1705, OMAP-L137

Hi,

I am currently using OMAPL137 EVM board & DaVinci-PSP-SDK-03.20.00.12 for Linux.

But for our project  AM1705 CPU will be used & a SDRAM will be connected to the EMIFB interface of the AM1705 CPU.

So can anyone guide me how to build SDRAM driver & how to interface it to DaVinci-PSP-SDK-03.20.00.12 kernel source.

Thanks & Regards

Jitendra

    Hi Jitendra,

    There is no SDRAM driver required. One has to initialize the SDRAM and it is done in UBL. Even on OMAP-L137, EMIFB is used to interface SDRAM. Modifications will be required in UBL, if a different SDRAM is being used than the one being used on OMAP-L137. Refer to DEVICE_SDRAMInit() function in device.c file in UBL source code.
