MSP-FET: 1901015ED

Have you select the driver as FET Debugger like  below

Have you select the debug protocol as automatic selection?

Thank you for your reply. Debugger-Setup-Driver is set to [FET Debugger]. The settings of FET Debugger are also informed.

Which demo code you do use? I can try it on myside.

Thank you for your suggestion.

IAR Information Center for MSP430

MSP430 Driver Library examples (MSP430FR2xx_4xx Family)

Example project using GPIO

First I found the demo at mspware ...\msp430ware_3_80_13_03__win\msp430ware_3_80_13_03\driverlib\examples\MSP430FR2xx_4xx\gpio\IAR

I open this project and found it is a project based on FR4133 and I found a launchpad of FR4133 to download the code and it works well.

Thank you for contacting.
Is it useless to reset the Device to MSP430FR2355? (Project-Options-General Options-Device)

You may need to modify some low level peripheral configuration. Because the pin out are different between the two devices.

Thank you for your valid information.
Is it necessary to change the hardware in addition to changing the Device settings of IAR ?
How should I change the peripheral device configuration.

I think you can start the demo code from here

TI_CCS-CODE of Example project is RUN operation OK, but in IAR-CODE Example project
The RED and GREEN LED on the MSP-FET lights up continuously and does not run.
I am seeking the cause of this failure.

Here is the meaning of the LED (https://www.ti.com/lit/ug/slau647o/slau647o.pdf?ts=1639483469783&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FMSP-FET%253FkeyMatch%253D%2526tisearch%253Dsearch-everything%2526usecase%253Dhardware )

If both of them lights up continuously that means it waiting for data transfer.
