MSP-EXP430F5529LP: Error when trying dsplib examples

Omer Faruk Basaran

I have the same problem in MSP-EXP430F5529LP: Unable to complete output buffer initialization - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums this post.

I tried the solution on e2e china. They said " Change the project configuration to 5529 and #define MSP_USE_LEA 0"

My configuration is already 5529 and I tried the changing MSP_USE_LEA to 0 but nothing changed.

Can you please help me I couldn't find any solution or information in anywhere.

This usually indicates that the Watchdog timer is expiring while .data/.bss initialization is still running ("too much" data).

You can try setting Build Settings->Build->Linker->Basic->Hold Watchdog Timer" to "on". This disables the WDT (only) curing C initialization.

Historically, the way to do this is to define a function something like [Ref Compiler User Guide (SLAU132X) Sec 6.9.1]:

int _system_pre_init(void)
{
    WDTCTL = WDTPW | WDTHOLD; // Stop watchdog before C init
    return(1); // Finish C init
}

I tried that suggestions but non of them worked.

After that I continued to research and in somewhere i found solution. It's caused from clock initialization, in default settings F5529 running at 1MHz, changing speed to 8 MHz(with cristal) solved everything.

Regardless thank you for interest Bruce
