AM4372: EMIF Tools Rev. A

Part Number: AM4372

Hi everyone,

I confirmed that AM437x_EMIF_Configuration_Tool was updated to v21.
So I applied the parameters used in v20 to v21.

Then there was the following difference in the register value.

So I want to know about the following.

Q1) Which value is correct?
Q2) Can I use AM437x_EMIF_Configuration_Tool v20 instead of v21?

Best regards,
Sasaki

Sasaki, some of the formulas were updated to produce more optimal configuration across many different use cases. For example, PHY_CTRL_36 was updated to better support low power suspend/resume. You should use v21 values for new designs or designs going through software upgrades.

v20 values are not wrong, and if proper stress tests were shown to be working, the configuration doesn't need to be changed.

Regards,
James
