CCS/F28M35H52C: Ethernet boot doesn't work

Part Number: F28M35H52C


Tool/software: Code Composer Studio

Hi,

I generated the code for m3 core using RAM configuration. The program works perfect in the debug mode. When I load the .bin file generated using LMFlash, it doesn't work. But I can see that C2000 core is started because I put a code in its flash and it blinks when I load the program by Ethernet port. It's like some modules or configurations doesn't work in Ethernet boot mode for m3. I'm using the DMA, ethernet port with uip and UART communications.

    zmeira,
    the entry point requirements for the application when using EMAC boot are different from other scenarios. Please take a look at the documentation and update the linker command file as needed.

    This is also discussed in the below forum post

    Hi Santosh,

    thank you for your fast respose. I already did that. This is my cmd file. I think I have a problem in my vector table because is where my code breaks. I put a IPC command in many places of the code and it stopped running when I put it after this commands:

    // Enable and register the Ethernet interrupt.
    IntEnable(INT_ETH);
    IntRegister(INT_ETH, EthernetIntHandler);

    This is my cmd file:

    MEMORY
    {
    C0 (RWX) : origin = 0x20000000, length = 0x2000
    C1 (RWX) : origin = 0x20002000, length = 0x2000

    Hi,

    I don't know why but I had to comment this to make my code work:

    At main program:
    InitPieVectTable();

    At InitAdc1() function:
    DELAY_US(ADC_usDELAY); // Delay before converting ADC1 channels

    Now I can generate a bin file that will be correctly executed.
