LOG_printf doesn't print

Hi Karl,

I'm using the SpectrumDigital XDS510 USB Plus, Yes, resetting the target helps,

Many Thanks,

Hi, Karl

I have the similar question. For example, i try to debug DSP BIOS 5 example "tsk". In this example, 3 tasks with same priority have been created with the Configuration Tool.  Each task has a computation loop consisting of a LOG_printf().

/*

 *  ======== task ========

 */

Void task(Arg id_arg)

{

    Int     id = ArgToInt (id_arg);

    Int     i;

    for (i = 0; i < NLOOPS ; i++) {

        LOG_printf(&trace, "Loop %d: Task %d Working", i, id);

        TSK_yield();

    }

    LOG_printf(&trace, "Task %d DONE", id);

}

But in Printf Logs does not display the first execution of LOG_printf! So, there's no record of "Loop 0: Task 0 Working"

We have the following:

time, seqID, formattedMsg, logger

1, 1, Loop 0: Task 1 Working, trace

2, 2, Loop 0: Task 2 Working, trace

3, 3, Loop 1: Task 0 Working, trace

4, 4, Loop 1: Task 1 Working, trace

5, 5, Loop 1: Task 2 Working, trace

6, 6, Loop 2: Task 0 Working, trace

7, 7, Loop 2: Task 1 Working, trace

8, 8, Loop 2: Task 2 Working, trace

9, 9, Task 0 DONE, trace

10, 10, Task 1 DONE, trace

11, 11, Task 2 DONE, trace

Can you check to see what size your logger is? It looks like the logger is wrapping and overwriting the first entry. If you increase the size of the logger, it should show up.

Hi, Todd

No, the size of logger does not affect the result. Printf Logs has the same result for all bios5 examples.

Currently, trace object declared as:

var trace = bios.LOG.create("trace");

trace.bufLen = 1024;

trace.logType = "circular";

But, when i try to debug step-by-step then all messages appear. Please, try create an new bios5 project with any template examples and check it.

Thanks
