LCK_pend with timeout 0 to sysbios

Kedar Josh

Other Parts Discussed in Thread: SYSBIOS

Hi,

I am porting an app from DSP/BIOS to current Sysbios. I have some issues with the LCK module. As the legacy note states that LCK has been replaced by gatemutex. but I can see that mapping is not one to one. I have a code which has LCK_pend(handle,0). Is there any way I can incorporate the timeout of 0 to gatemutex?

Thanks

Hi Kedar,

No. You cannot specify timeout for the Gate modules. Please refer to the following for more details: http://e2e.ti.com/support/embedded/bios/f/355/t/253141.aspx

Hi Josh,

GateMutex does not support timeouts. GateMutex also internally uses a binary semaphore and If you would like to specify a timeout, you can try using a binary semaphore directly. Semaphore _pend() allows you to specify 0 timeout (BIOS_NO_WAIT).

Best,

Ashish
