Linux/BQ27545-G1: Reset time after DM update of flash gauge

Liam

Part Number: BQ27545-G1

Tool/software: Linux

Is there a delay during which a flash (ie non-config-update) gauge resets itself after BlockData and BlockDataChecksum are written?

For the 545, I see "DF block write typically requires a maximum of 72 ms" but I don't see mention of chip reset time.

It will not reset itself. Once you write the check sum you should wait approx. 100ms for the data flash update to finish.

Will the update appear in chip RAM (i.e. impact gauge function) after data flash update? Or does that require reset?

Some parameters (e.g. design capacity) require a reset for the firmware to reload them. To guarantee that all parameters are updated correctly, a reset is recommended.
