IWR1443: Semaphore timeout

Hi Horoyuki,

Could you please provide some additional context on how you are testing this (breakpoint, print statements, etc...)? Also have you ensured there is no task prioritization issues that could be causing this?

Best Regards,

Josh

Hi Josh,

A1.I added the following code at the end of the TIDEP-0091 demo main.c init_Task function to check the UART output messages.
It will be confirmed by Flashing, not on the CCS debugger.

TIDEP-0091 mein.c init_Task() additional code:

CLI_init();

Semaphore_Params_init(&semParams);
semParams.mode = Semaphore_Mode_BINARY;
gMmwMCB.endSpiSlaveTransaction_semHandle = Semaphore_create(0, &semParams, NULL);

SemaphoreP_Status status;
CLI_write("semaphore wait\n");

status = SemaphoreP_pend(gMmwMCB.endSpiSlaveTransaction_semHandle, 100); //for semaphore wait test

if (status == SemaphoreP_TIMEOUT)
{
CLI_write("semaphore timeout\n");
}
else
{
CLI_write("semaphore ok\n");
}

Create init_Task:

Task_Params_init(&taskParams);
taskParams.stackSize = 6*1024;
Task_create(init_Task, &taskParams, NULL);

A2.>Also have you ensured there is no task prioritization issues that could be causing this?
Could you give me some specifics about the task priority issue?
Does it mean that there is a task priority constraint for the semaphore timeout function?

Best Regards,

Hi Josh,

I was able to solve the issue that the semaphore_pend timeout does not work.

It was caused by the following settings in mss.cfg.

BIOS.clockEnabled      = false;

What is the difference if BIOS.clockEnabled is true or false?

I couldn't find an explanation of this setting in the SYS/BIOS user guide, so could you point me to some reference documents?

Best Regards,

Hioryuki
