CC2652R: TI-RTOS Configuration "Semaphore.supportsEvents = true"

Stuart Baker

Part Number: CC2652R

I am working with a customer who is wanting to use this feature. Because of the existing comment in the example *.cfg file, we are wondering what happens if we intend to use RTOS in ROM and set this option:

* Allows for the implicit posting of events through the semaphore,

* disable for additional code saving.

* Pick one:

* - true

* This allows the Semaphore module to post semaphores and events

* simultaneously.

* - false (default)

* Events must be explicitly posted to unblock tasks.

* When using BIOS in ROM:

* This option must be set to false.

Semaphore.supportsEvents = true;

//Semaphore.supportsEvents = false;

For example, would the impact be that the Semaphore feature gets pulled into FLASH? ...or would the impact be that the entire RTOS gets pulled into FLASH?

Thanks,

Stuart

Hey Stuart,

Using BIOS in flash instead of ROM is all or nothing:

/* ================ ROM configuration ================ */
/*
 * To use BIOS in flash, comment out the code block below.
 */
var ROM = xdc.useModule('ti.sysbios.rom.ROM');
if (Program.cpu.deviceName.match(/CC26/)) {
  ROM.romName = ROM.CC26X2V2;
}
else if (Program.cpu.deviceName.match(/CC13/)) {
  ROM.romName = ROM.CC13X2V2;
}

So if you want to set Semaphore.supportsEvents = true; then you have to comment out the code above. You can see the affect this has on flash by comparing the generated MAP files.

Regards,
Ryan
