Part Number: MSP432E401Y
Other Parts Discussed in Thread: UNIFLASH,

I have installed the Scalable-PMICs-GUI_2.0.0_installer_win and gcruntime-8.0.0-windows-installer (1).exe， and update the aevm_1_0_3_5.txt  version to the msp432e401y using uniflash. I open the PMIC GUI，and plug the msp432e401y launchpad to the PC USB，the devcie settings Window can not select port，like the picture below. How to fix this problem?

    It is my fault ，I should plug the MSP432 side USB port，not the XDS110 USB port， now the PMIC GUI can connect to the launchpad ， but

    use GUI quick start  can not scan the PMICs， and the screen still last in the scan picture ， I find this from other E2E issue like mine，if it has been solved for now?

    Hi Pengpeng,

    I'll have to check with the team that developed this GUI to see if they can provide some assistance.

    Hello,

    In the device manager window you should see this:

    The USB on the application side (same as the ethernet connector), provides 5V to the system but unless both the OTG and JTAG jumpers are in place on the launchpad there is no way for the 5V to get to the 3.3V LDO and consequently there is no 3.3V on the board.  In the example above, I simply connect to both USBs.  the USB on the XDS110 provides the 5V to the 3.3V LDO.  Please refer to the launchpad user's guide.  

    The GUI has not been updated for the latest silicon (May 2022), so the quick start page will not recognize the device ID of the PMIC.  Please use the register map page until the GUI is updated.  

    Please be advised that the launchpad does not have pullups and is in the 3v3 domain.  Please check the pullups on the I2C as well as confirm that the voltage domain is the same (PMIC can operation at 3.3v or 1.8V VIO).  Also check the ground connection between the launchpad and the target.

    Regards,
    Chris
