Hi
we are using following parts and facing issue in ddr bringup.
1. processor - imx6dualite
2. DDR - micron - MT41K256M16TW-107 IT
Note: USB OTG is not available on our custom board. Boot mode is set to SD card boot.
Here we have attached the DDR script and configuration used.
We would like to know whether we are missing anything important.
Original Attachment has been moved to: eliuaccs6sdl_tmp.cfg.zip
Hello,
Please use the following documents how to configure DDR parameters.
https://community.nxp.com/docs/DOC-101708
i.MX6 DDR Register Programming Aids
Note, timing parameters for the MT41K256M16TW should be set,
assuming that i.MX6 memory frequency is 532 MHz, that is memory
parameters for Data Rate of 1066 should be used.
For example tRCD=tRP=CL (ns) in Your table is 13.75 ns, it may be
recommended - 13.1 ns (really Your settings should not provide problems).
tRC = 39 ns in the case, but it would be better to apply 52.5 ns.
You selected DRAM Clock Freq (MHz) of 400 MHz, this means DDR3-800
specs should be applied.
Have a great day,
Yuri
