Dear All,

Our customer connects LPDDR memory to i.MX28.
(LPDDR: NT6DM64M16BD-T3)


They tried to set Drive Strength to this LPDDR using HW_DRAM_CTL183 register of i.MX28.
However, Drive Strength of LPDDR did not change.

According to the reference manual, the following is explained.

"For LPDDR1 memories: This parameter has no meaning for this memory type."

MCIMX28RM.pdf(rev2):
- 14.8.172 DRAM Control Register 183 (HW_DRAM_CTL183) (P.1322-1323)


Is there any method of setting up or changing Drive Strength of LPDDR?

Best Regards,
Yuuki
