Part Number: MSP432P401R
After attempting to upload the code shown below to my MSP432 launchpad, the board entered a constant reset cycle and could no longer be flashed through my board's debugger.
/* DriverLib Includes */
#include <ti/devices/msp432p4xx/driverlib/driverlib.h>
/* Standard Includes */
#include <stdint.h>
#include <stdbool.h>
#include <stdio.h>
//![Simple GPIO Config]
int main(void)
{
volatile uint32_t ii;
/* Halting the Watchdog */
MAP_WDT_A_holdTimer();
/* Configuring P1.0 as output */
FPU_enableModule();
GPIO_setAsOutputPin(GPIO_PORT_P1, GPIO_PIN0);
CS_setDCOFrequency(CS_DCO_FREQUENCY_48);
uint32_t volatile freq = CS_getDCOFrequency();
while (1)
{
/* Delay Loop */
// for(ii=0;ii<50000;ii++)
// {
// }
__delay_cycles(50000);
MAP_GPIO_toggleOutputOnPin(GPIO_PORT_P1, GPIO_PIN0);
}
}
//![Simple GPIO Config]
This is the error output:
I don't think the device is bricked, but I would like to be able to use this MSP432 for my project instead of the MSP430.
I tried multiple factory resets and also tried reducing the JTAG CLK frequency
I had previously run some simple GPIO code successfully on this board so I know it was working before I tried the code mentioned about. Apparently, as specified in the DriverLib Manual in section 6.6.2.23, pre-released launchpads can't use the setDCOFrequency() function to anything outside of the preset freqs, which I may have done.
In any case, that's what I know so far, and I would appreciate any help or insight on this issues so that I can save my launchpad
