Trying to use tx_semaphore_put_notify in ThreadX. Calling it returns 0xff which the TX manual says
Is this not available in SSP, or is there a way to enable it?
Hi Cam,
You need to add the ThreadX Source in the configurator and then enable the property for Notify Callbacks to enable this feature. The library build has this feature disabled by default to save space.

That simple? It needs to be added to each thread that uses it, correct?
No - Just once in you configuration.
yes, saw that as I was adding it.so I enabled Notify Callbacks and disabled Show Linkage Warning. Then generated Project Content and did a rebuild. And the code is unresponsive, seems to be stuck. I'll start trying some ideas, but are there other settings in the custom ThreadX configurator that should be enabled/disabled to better match the prebuiilt ThreadX?
When you include the source, the default settings that the prebuilt ThreadX are the same until you modify them.
Cam,
If you are using any other Xware (NetX, UsbX, GuiX) components, you must also include them as source so that they can be recompiled with the changes to the ThreadX settings.
ok this makes sense. but now i get an error about (understandably) "source and pre-built library should not be combined in the stack. (this puts g_ux_device_class_cdc_acm0 of g_sf_comms, the original USBX stack, in red in the configurator.) so before i do something i can't reverse, i'll ask how to remedy this: do I delete the original USBX stack and then re-add it? (note this is the only Express Logic stack used in the project.) i assume the original prebuilt library was installed when USBX stack first added, so deleting and then add-ing it back will cause it to see and use the USBX Source stack?
No - you don't need to delete the USBX stack - just add the USBX source in the configurator.
