CCS/MSP430F2617: MSP430F2617 executes random code when voltage is shut down

Part Number:MSP430F2617

Tool/software: Code Composer Studio

Hello all,

this time i got another tricky question for all of you, wheather one has expirienced this behaviour before :)

We do have a board with a MSP430F2617 and some FRAM attached to it via I2C and a lot other stuff going on, but now after some time in field the following corruption of FRAM ( remember this one is external not internal to the MSP430) did happen.

Some address, always the same, did get overwritten and at first look we did not know why this was happening.

After some investigation now, we found out that indeed the MSP430 is executing an I2C FRAM write command, which was completly unreachable in the

while(1) loop.

So we probed the I2C pins and the Vcc of the MSP430, and around 2 V Vcc ( after shutdown the 3V3 took about 20 ms to drop down to 0 V ) the MSP43ß I2C line is executing a write to exactly the Adress that

gets corrupted in field.

So here is the question to the experts: Have you ever expirienced behaviour like this?

What could be triggering this execution of some rather random code snippet, maybe the program counter is set to a certain value when some brown out happenes?

Note that as a workaround, for example setting the voltage supervisor in hardware to around 2,5V will help, also altering the written code in the while(1) loop, by for example adding another if(flag== blablba){

will also help to get around this problem.

But all those things treat the symptoms and not the root cause i fear, so I would rather prefer some explenation of that phenomenon.

And what does the MSP430 do when reaching the voltage supervisor level, does it halt internally? or shut down? or simply only set a flag, but executes the following codes anyway?

Thanks a lot for reading.

Dear All,

We're trying to use MSP432P401R and the screen Kentec BOOSTXL-K350QVG with ENERGIA and we have some problems depending of the version of Energia and also the computer.

For instance, if we use the last version of Energia 1.8.7E21 there's no library for the screen kentec and it don't work.

For using the Kentec BOOSTXL-K350QVG, we have to use Energia 1.6.10E18 and with some computers, it don't work !! Could you confirm that ??

Thanks for your help and best regards,

Hello,

What is the difference between the USS and USS_A module? Does this mean there are 2 USS module or only one? USS_A has an extended pulse generator means it is used when we do DUAL tone generation? this is what understood. please update me on this.

MSP432P4111: Custom board bring-up: after initial program load, debugger error -1170 cannot access DAP

Part Number:MSP432P4111

Hi, 

I am attempting to bring up a custom board with an on-board MSP432P4111 but having problems connecting to the DAP. The device is daisy chained with a CC2650, and I have set up a target configuration as shown below.

I have bypassed the CC2650 for now:

And the connection test succeeds (for both JTAG and SWD).

I ran a project-less debug session by launching this target configuration, and I was able to connect to the MSP core and load the program. I could see it had entered the main() function, but as soon as I attempted to step through the target disconnected and stopped working!

Now if I try and connect I get the following error:

I've been through several posts with this error I've found in the forum but I am unable to connect to the target at all, which I don't understand as I was able to connect briefly once. I had included the board configuration file in the program, could this lead to the problems I am seeing?

Why would this happen on a custom board? Is it related to the BSL? In the FAQ I noticed this 

Q-a: What is the consumption when there is no code in the MSP432 flash (after a full erase)?
Q-b: What is in MSP432 MCU flash when shipped to customers? What code runs at start up when received from TI shipment?

A: For both questions: MSP432 microcontrollers (flash) are fully erased when shipped to customers. When the flash is empty (specifically when the reset vector + SP are empty), boot code automatically puts the device in BSL mode. If there’s no BSL activity after some time, device automatically goes into LPM4.5 mode, consuming <100nA.
 
Is this what could have happened with the device on my board? How do I recover from this issue?
Thanks,
Meenal

HI

I need to store data ( 3 or 4 words maxi ) in non volatile memory of the MSP430G. When some parameters change on my application I need to store them with the user program. (then read them after a power on )

How can do that and to be sure to write these data and to be sure to not over write my user program ? (assume my user program don't use all the range of flash memory)

Part Number:MSP-EXP430FR2433

Hello everyone,

I am using the MSP-EXP430FR2433 board along with Energia for a college course in computer design.

Unfortunately I have been having trouble running code to the board as I get a error every time I try to upload, which is the following:

"error: MSP430: Error initializing emulator: No USB FET was found
Failed: MSP430: Error initializing emulator: No USB FET was found

the selected serial port does not exist or your board is not connected"

Things I have tried so far:

Restarts with and without board connected.

Different cable than the one that came with the board.

Reset button on board.

Reinstalled Energia, and the drivers that installed for the board.

Try different USB ports.

Turned off windows defender.

Made sure board showed up in device manager (was under "Ports COM & LPT")

Browsed these forums for an answer

Installed Energia and board on different computer, same issue occurred.

Any help is appreciated, thank you.

Hello,

I want to use accurate time using RTC timer. but I have never considered temperature compensation when I use RTC_C.

So that I checked that RTC time is faster more than expected time approximately 2 seconds a day. (2019.01.29 12:00:00 -> 2019.01.30 11:59:58)

If i can measure temperature data, plz provide me with how to use RTCTCMP register.

 If I get a temperature zero degree Celsius, how to use RTCTCMP register?

I can refer to 'ULP Temperature Compensated RTC on MSP430F6736 Degign Guide' (URL: http://www.ti.com/lit/ug/tidu600/tidu600.pdf

Hi community member,

The following questions about FLL are received from my customers using MSP430F6726.

① What is the fluctuation range due to the 1 bit fluctuation of the MOD bit?
(For the DCO bit, it is described as 2% minimum and 12% maximum with about 8% in 1 step.)

② What is the cycle of the FLL correction operation?

If you know the answer of the above, please tell me.

Best regards.

CCS/MSP430G2452: Pressing a button turns the whole device off?

Part Number:MSP430G2452

Tool/software: Code Composer Studio

Hello, I have a question.  I am using the MSP430G2452 with the Launchpad Development board and am trying to practice using the I/O pins.  Here is code that is supposed to turn an LED on a breadboard off when the button is pressed:

#include <msp430g2452.h>

// P1.4 is the led
// P1.5 is the button

#define LIGHT BIT4
#define BUTTON BIT5

int main(void)
{
    WDTCTL = WDTPW | WDTHOLD;   // stop watchdog timer

    P1DIR |= LIGHT;
    P1REN |= BUTTON;
    P1OUT |= BUTTON;

    while(1){
        if((P1IN & BUTTON) == 0X00)
            P1OUT |= LIGHT;
        else
            P1OUT &= ~LIGHT;
    }
}

What happens, however, is that the whole board will turn off when I press the button, not just the LED.  So when I press the button on my breadboard, the device acts as if I just disconnected the device from the computer.  Does anybody know or can see why this is happening?  Thank you for your time

CCS/MSP430F2617: MSP430F2617 set the SVSCTL to wrong value, now programmer does not detect device anymore, how to reset

Part Number:MSP430F2617

Tool/software: Code Composer Studio

Hello,

odd things do happen to me these days.

I was playing around with the voltage supervisor, had the following code:

        SVSCTL |= 0x60;		// 2,5V
	SVSCTL |= 0x80;		// 2,8V
	SVSCTL |= PORON;

I did not comment out the first line so in aggregation the bits were set to 3,7 V PORON generation,

so of course if i treat my MSP normally with 3,3V the PORON is always set, holding the device in the reset state!!!

I did try the uniflash tool, and different settings in CodeComposer, it will simply not detect my module anymore, could I really brick my device this halarious way?

I thought the JTAG debug interface would recover the device from almost any state.

Maybe someone has an easy answer, or maybe my problem is related to something different.

Thanks a lot.
