LAUNCHXL-F280049C: Problem SPI communication between 2 boards

Hello,

I am studying how this micronctroller works and I am having problems understanding how to properly set a communication between two LAUNCHXL-F280049C via SPI. 

I would like to transfer an array of 11 elements of uint16_t type using the FIFO interrupts from the master to the slave. My configuration and code are the following (I am using sysconfig).

Board 1 TX ISR(master): 

__interrupt void spiTxFIFOISR(){

    for(i=0; i< dim; i++){
        SPI_writeDataNonBlocking(mySPI0_BASE, data[i]);
    }

    counter++;

    SPI_clearInterruptStatus(mySPI0_BASE, SPI_INT_TXFF);
    Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP6);
}

Board 1 sysconfig: 

Board 2 RX ISR(slave):

__interrupt void spiRxFIFOISR(){

    for (i = 0; i< dim; i++){
        data[i] = SPI_readDataNonBlocking(mySPI0_BASE);
    }

    counter++;

    SPI_clearInterruptStatus(mySPI0_BASE, SPI_INT_RXFF);
    Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP6);
}

Board 2 sysconfig: 

(Note that I have enabled and remapped both the interrupts in the setup part of the main which is not present in the shown codes)

I expect to receive correctly the array of data I am sending on the slave but what I see is the same array shambled at each iteration of the receive interrupt. Could you explain me what I am doing wrong? I am following the example provided by TI for the SPI communication but I don't get where are my mistakes.

On the left there's the array I am sending while on the right there's the array I receive.

Thank you in advance .

Best regards,

Edoardo
