GPS showing scrambled output on Serial monitor

[LoveShadow 0]

Hello! I've got a problem when I want to show the output on serial monitor of a GPS. 

When I put a basic example (fade example) and the TX of the GPS on the TX of MSP430 (P1_2 pin) the output shows good, without any problem. The baud rate was the stock one (9600).

 

When I try to make the same thing on other pins (I've choosed RX of GPS to P1_3 and TX of GPS to P1_4) a scrambled output takes place on the serial monitor and I don't really know what to do.  

I'll attach the code, maybe it's a code issue. Thanks in advance!

I'm new in this so take me easy please

#include <SoftwareSerial.h>
static const int RXPin = P1_4, TXPin = P1_3;
static const uint32_t GPSBaud = 9600;
// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);
void setup()
{
  Serial.begin(115200);
  ss.begin(GPSBaud);
}
void loop()
{
  // Output raw GPS data to the serial monitor
  while (ss.available() > 0){
    Serial.write(ss.read());
   // delay(10);
  }
}

Sorry, thought it would be enough what is in tags.

Keep in mind the MSP430G2553 has only 512 bytes of RAM. It may not be enough for the buffers of two serial ports.

Try with a more capable MCU.

I've tried with this one as well, and it did not work. https://www.electronicwings.com/ti-launchpad/gps-module-interfacing-with-msp-exp430g2-ti-launchpad
