Hi,
I'm new to DM816x and current'y i want to play around with the memory part.I had read through the technical reference manual but, i facing some problems here...
1)In order to configure the ddr3 memory, which controller should i focus?DMM or DDR3 Memory Controller?From my understanding, the DMM is the Dynamic Memory Manager for the DDR EMIF and the DDR EMIF is the DDR bank controller.Do i correct?
2) How to reserve, read and write the DDR3 SDRAM memory in DM816x?Which header file should i refer to?
3)Currently, i just using request_mem_region() and my physical memory is start from 0x4E00 0000 and i reserve the memory size for 0x8000. But, when i insmod the my driver, there is a error come out: unable to obtain I/O memory address 4e000000.How can i debug it?
Thank you.
