Hi all

 

 

My customer have a question about settings of DCD file so please tell me.
They're building a custom board with i.MX6DL and trying to make DCD file for their board at same time.


First, they compared following two files.

One is mx6dlsabresd.cfg.
Another is the file which is based on the Datasheet of MT41K128M16JT-125's.


Then, they found a different settings between those files.

In MX6DL_SabreSD_DDR3_register_programming_aid_v2.0.xlsx, the MMDC0_MDOTC value is 0x1B333030.
On the other hand in mx6dlsabresd.cfg, the MMDC0_MDOTC setting is 0x00333030.

They got MMDC0_MDOTC value from the datasheet so we guess that 0x1B333030 is correct.

Also they concerned about they need to set "0" to tAOFPD and tAONPD fields.


Please tell me the correct setting.

 

 

Add info:

They use a MX6DL_SabreSD_DDR3_register_programming_aid_v2.0.xlsx that can download from following link.
https://community.nxp.com/docs/DOC-105964

MT41K128M16JT-125 is SDRAM memory which is used for MCIMX6DL-SDP.
