RTOS/AM3359: Task definition

Part Number: AM3359

Tool/software: TI-RTOS

Hi TI,

beaglebone black, processor SDK RTOS 4.2.0.9, ccs 7.4

I am working on SPI data transfer with TI-RTOS on BBB board, and seeing the following codes in the example project main() function.

    Task_Handle task;
    Error_Block eb;

    Error_init(&eb);

    task = Task_create(spi_test, NULL, &eb);
    if (task == NULL) {
        UART_printf("Task_create() failed!\n");
        BIOS_exit(0);
    }

I expect the above codes are equivalent to the definition of task0 in app.cfg (ref the attached screen-shot below), and I commented out the above codes in the main() function. Obviously they are different. The compile error message did not reveal too much useful information (also shown on the screen-shot).

Please advise, thanks in advance,

Please copy complete build log from your console and attach it as a text file for us to analyze the error. If may also help if you attach the .cfg file after you added the task using XGCONF tool.

Regards,
Rahul

Hi Rahul,

I solve the puzzle by myself.

In .cfg file, uart should be defined before loading the board package. Then everything works like a charm.

/* Load the uart package */
var socType = "am335x";
var Uart = xdc.loadPackage('ti.drv.uart');
Uart.Settings.socType = socType;

/* Load the board package */
var Board = xdc.loadPackage('ti.board');
Board.Settings.boardName = "bbbAM335x";

Thank you for the help

Mike
