MSP430FR6989: Part does not work

Hello  Kwang,

Ok, let's see what I can do for you.  Since I don't know the history of who you contacted, do you remember goint to our Customer Returns webpage?

Did you purchase this through a distributor or directly from TI directly?

If you purchased this through a distributor you will need to contact them regarding a replacement.

Out of curiosity, can you program the FR6989 with the simple code shown below that toggles the RED LED (P1.0) on the launchpad?  This will tell me if the issue is with the MCU.  Make sure when you program you don't see any error messages from the programmer. 

Are you using CCS?  Windows PC?

#include <msp430.h>

int main(void)
{
    WDTCTL = WDTPW | WDTHOLD;               // Stop WDT

    // Configure GPIO
    P1DIR |= BIT0;                          // Clear P1.0 output latch for a defined power-on state
    P1OUT |= BIT0;                          // Set P1.0 to output direction

    PM5CTL0 &= ~LOCKLPM5;                   // Disable the GPIO power-on default high-impedance mode
                                            // to activate previously configured port settings

    while(1)
    {
        P1OUT ^= BIT0;                      // Toggle LED
        __delay_cycles(100000);
    }
}

Here is where I got this example that toggles P1.0.

In response to TI's email inquiry from mailto:ticsc@service-now.com

I replied,

In previous chat conversation, I believe I stated that there is NO LCD display running Out of Box demo program.

This demo program has been loaded into LaunchPad using CCS version 10. 

I believe it’s for your benefit that TI gets the defective unit back from me, and figure out what went wrong with LCD display functionality.

I really don’t have resources to troubleshoot the cause of LCD display’s functionality.

In addition, order number for this batch is T00788597 and the case number is CS0219439

Hi Kwang,

I have reached up the chain of command to help expidite this.

Thank you for providing the additional information.  I am trying to contact the sales team regarding this information.

Yes, we certainly want to know if this is a defect.

To help you as quickly as possible,  I still do need to know where you purchased the launchpad from?

And, did you have an opportunity to try programming the simple example to test the MCU?

Hi Kwang,

I spoke with our customer support folks and they indicate they can only help if you purchased this launchpad through ti.com.

If purchased through a distributor you need to contact them.

Assuming you did purchase through ti.com,  I need your help to establish what the failure is, that's why you need to try that simple code.

Once it's determined defective, I'll note that here in this thread, then you will need to contact TI support via their chat interface  and provide a link to this E2E thread.

This order batch was through TI.COM.

This is why I included order number, T00788597.  See earlier post.

Please read my response more thoroughly so that we may eliminate this kind of nuisance correspondence.

Hi Kwang,

That order number is tied to your TI account.  I don't have access to that information.  I'm merely following instructions from the customer team that get you a replacement.

I'm merely doing my job to help determine what the issue is.

Ok, then based on your description it appears the LCD display or the MCU is faulty and it is my opinion this launchpad needs to be replaced.

The next step for you is to contact TI support via their chat interface  and provide a link to this E2E thread.  Someone in the customer team will handle your return/replacement.

Have a good day

I know you're trying to help.

I just got little impatient have two out of 4 board that was defective.

Can you also help me with this sensor board??  https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/916901

Thanks for your help.
