TMS570LC4357: SDRAM LMR Command

Part Number: TMS570LC4357

Hi,

I am trying to interface onboard SDRAM(refer IS45S16320F-7TLA2) in TI TMS570LC4357 Hardware Development Kit,

Initialization done as per the SDRAM requirement. Read and Write also working good.

My understanding in interfacing SDRAM with EMIF is, Read and Write operations are done directly through accessing memory address (0x80000000 in my case).

so, Read and Write operation itself is Read and Write commands sent to SDRAM. [Let me know if i am wrong].

My query is, How to write LMR command to SDRAM and How to change LMR command Parameters as per the user wish.

Please clarify the above concept.

Thanks and Regards,

Bharath
