MSPM0G1106: Problem with Default Handler

Part Number: MSPM0G1106

Hi!

I'm having a problem with the MSP0G.

I've alread had this problem with a PG1 unit, and the answer was to change to a PG2 microcontroller.

I've already have the NEW PG2, and as I understand, it is not really the 1106, the unit that TI sent was an 3507 but being a 32 pins unit, with the same layout as the 1106.

The main problem is that after 10 seconds of the code to start running, it is being sent to the Default_Handler witn an Exception 011b, which is the HardFault_Handler.

I am currently running:

- Systick

- 2 free running timers (TIMA1 and TIMG6).

- Two I2C Channels:

    - Multimaster mode with interruption.

    - Master mode with polling to an EEPROM.

 - TIMG0 as a 10 ms timer with interruption.

- PWM TIMG12.

- Compare timer ( 16 edge counter )  TIMA0 with interruption.

Sincerely I don't know what to do.

I'll appreciate your help
