Original question:

CC3120: Does it necessary to implement sl_SyncObj/sl_LockObj in non os environment.

CC3120: _SlNonOsSemGet() compilation error.

Part Number: CC3120
Other Parts Discussed in Thread: CC3100

Hello Team,

Could I directly use the CC3100 sl_SyncObj/sl_LockObj implementation of non os environment for CC3120 or We will have to do some changes? 

I have just copied sl_SyncObj/sl_LockObj implementation from CC3100 into CC3120 for nonos environment (nonos.h/nonos.c) and compile it and got error on this part of code (inside of function _SlNonOsSemGet).

It is showing error that IsCmdRespWaited and _SlNonOsMainLoopTask() undefined. So I have changed "IsCmdRespWaited" (CC3100) by WaitForCmdResp (CC3120) and also changed "_SlNonOsMainLoopTask()"(CC3100) by "_SlNonOsHandleSpawnTask()"(CC3120) then code properly compiled. Do you confirmed that what I did changes will work on CC3120 without any problem or is there any more changes required?

/* If we are in cmd context and waiting for its cmd response
* do not handle spawn async events as the global lock was already taken */
if (FALSE == g_pCB->IsCmdRespWaited)
{
(void)_SlNonOsMainLoopTask();
}

Kindly help me out.

    Hello,

    Please note that the implementation between CC3100 and CC3120 in terms of SDK has been changed completely.

    With CC3120, the SDK uses the same methodology for all RTOS, including non-RTOS.

    The non-RTOS uses a SW layer that is called DPL. You can see it in the CC3120 SDK and its WiFi plugin.

    If you intend to port your appliaction, I suggest you move to the new SDK.

    The process you mentioned might work but I cannot guarantee.

    Hello Shlomi,

    I think you did not get my question, I am porting host driver of CC3120 to STM32 for non rtos environment, but I got compilation error that sl_SyncObj/sl_LockObj are not defined. So I asked question on e2e forum how to implement these os adaption layer (sl_SyncObj/sl_LockObj ) for non rtos environment then I got answer that you can use CC3100 SDK method for implementing sync and locking objects (e2e.ti.com/.../690115).

    So I have copied sl_SyncObj/sl_LockObj implementation from CC3100 into CC3120 for nonos environment as mentioned in this thread e2e.ti.com/.../690115.

    I need to know that it will work properly or not?

    Kindly help me out.

    Thanking You

    Regards,

    Shubham

    Hello,

    You mentioned CC3100 so I figured you are trying to port it from the older SDK.

    In thsi case, Michael's response looks OK and the code adaptation also goods good.

    I do not see an issue with this implementation.
