Hi,

I follow this post want to run 'empty' project:

e2e.ti.com/.../1187689

Below is what is modified:

int main(void)
{
    /* Call board init functions */
    Board_initGeneral();
    Board_initEMAC();
    Board_initGPIO();
    // Board_initI2C();
    // Board_initSDSPI();
    // Board_initSPI();
    // Board_initUART();
    // Board_initUSB(Board_USBDEVICE);
    // Board_initUSBMSCHFatFs();
    // Board_initWatchdog();
    // Board_initWiFi();

    /* Turn on user LED */
    GPIO_write(Board_LED0, Board_LED_ON);

    System_printf("Starting the example\nSystem provider is set to SysMin. "
                  "Halt the target to view any SysMin contents in ROV.\n");
    /* SysMin will only print to the console when you call flush or exit */
    System_flush();

    /* Start BIOS */
    BIOS_start();

    return (0);
}

I have increased Heap size to 24KB, see below please.

There is still error as below:

What else could be wrong?

    After adding a missing component at IP block, it has the following echo message. Hopefully it is the desired output.

    Using MAC address in flash
    Starting the example
    System provider is set to SysMin. Halt the target to view any SysMin contents in ROV.

    NDK task priorities

    but I cannot find it on XGCONF.

    Here is an image copied from the forum. How to get this sub-menu (could you give me the steps to get there?)?

    I need to set

    It is found that tcpEcho project has such message:

    ss in flash
    Starting the TCP Echo example
    System provider is set to SysMin. Halt the target to view any SysMin contents in ROV.
    Service Status: DHCPC : Enabled : : 000
    Service Status: DHCPC : Enabled : Running : 000
    Network Added: If-1:192.168.0.113
    Service Status: DHCPC : Enabled : Running : 017

    Comparing with tcpEcho project, empty project is similar but has not the last two lines above. What could be the cause?

    It is found that DHCP works after removing EMAC. Then, it is seen that it may be the problem of missing EMAC device driver, but I cannot find where to find and enable EMAC device driver.
    Could you tell me that?

    First, what version of TIRTOS are you using?

    Its more prudent to go through the documentation/examples before you just start posting questions as it seems you answer several of your own questions already.
