Hi,
I am using beaglebone.
I plan to access the fpga/DDR connected on gpmc interface in multiplexed synchronous 16bit mode.
Although i have already tested the changes using "/dev/mem" and user application to access the gpmc config registers.
Now i plan to do the final implementation in u-boot and kernel for the 2 chip selects and memory region, and doesn't want to change during runtime.
the DDR above is different than the normal ram used in the system. this is used for some video patterns contents we need to write over gpmc to be finally projected on projection device.
Can you please guilde me how to go about following things,
1. which file to use in u-boot for configuration, include/configs/omap3_evm.h or omap3_beagle.h?
2. where/what changes to changes to make for CS regions for 2 memory map regions? example code would be helpful.
3. Changes i need to do for kernel for mtd partition settings.
TIA
Vikas Rustagi
