MSP430FR5989: ESI doesn't work on FR5989

Samuel Pérez

Hi all,

I did a previous post where I explained that I'm migrating my EVMSP430FR6989 into MSP430FR5989 chip, the application on 6989 works well and the things I took in mind for migrating was:

GPIO ports (they are not the same, so first of all I've put all of them to output low, later I will use the ones i want)
Everything about LCD off.
Interrupt handler for turn on/ff the LCD out.

The thing is that the micro is doing strange things since the beginning, I've debugged and it stops in esiConfig() function, where the DAC, PSM and so on are initialzed (i've turned on the motor disk). and still does weird things.

This is a caption of power consumption, seems like it's on a timer or something like that. Does anyone has an idea of what can it be? Or something I've should done in the migration part?

Best regards

Hi Samuel,

I would look at the linker command files between the FR6989 and FR5989 versions. Are you migrating a software project provided by TI?

BR,
Leo

Hi Leonardo,

Thanks for your reply. Yes, the program in fr6989 was originally generated by FLOW ESI GUI of TI, I've just modified it to our needs (some interrupts for the clockwise and anticlockwise rotation and LPM) and the linker files is basically the same, because the library is valid for 5XXX and 6XXX series so I think nothing shuld change with it.

Best regards

I've found the problem, inductances were conected to ESICI0 and ESICI1 instead of ESICH0 and ESICH1.

Best regards
