Hi,

Which BQ-BMS-PROGRAMMER-SW.exe file should i use for BQ27Z746 when programming golden image using MKS-SAI-001?

I tried with Prog27z5.exe and Prog28Z6.exe, but both also not working.

Below is 2 subsequent runs using one of the exe file:

C:\Program Files (x86)\Texas Instruments\BQ-BATTERY-PROGRAMMER-SW\BQ-BMS-PROGRAMMER-SW\CommandLineProgrammers>Prog27z5.exe -i -p 1746_0_01-bq27z746_LearningCycleAttempt1.srec -v

    BQ-BATTERY-PROGRAMMER-SW works with the MKST-3P-ALT-EV2300 interface. TI hasn't tested this with the MKS-SAI-001 adapter. This looks like MKS didn't make these adapters compatible and only tested them with the SW packages that are mentioned on their list of compatible applications.
