i.MX8M Plus LPDDR4 burst length setting

Hi NXP,

Is the i.MX8M Plus able to support BL=32 and BL=16 or 32 (on the fly) of LPDDR4?

Thanks.

Hi Jimmy,

Thank you for your reply. I tried to modify the Burst Length setting to BL32 through MR1 in the cell D213 of the RPA. Then run the Stress test on the 8MP EVK board. But I got a fail result.

So I want to know whether the 8MP can support BL=32 or not.

Thank you for your help.
