4.4.1 Semaphore

In TI-RTOS, semaphores are used for:

  • Triggering the SciServer User tasks execution
  • Synchronizing between the two SciServer User tasks

The code for initializing the semaphores can be found at $J7SDK/ti-processor-sdk-rtos-j721e-evm-xx_xx_xx_xx/pdk_jacinto_xx_xx_xx_xx/packages/ti/drv/sciclient/src/sciserver/sciserver_tirtos.c functionSciserver_tirtosInitSemaphores() and PDK’s public GIT here.
