PN7462 DoorAccess Example with NULLRTOS

Hi

We have just started experimenting with PN7462 using NXP's development. We have tried the Basic Discovery Loop example and successfully build it with NULL_OS option.

 

The door access example seems to be the most relevant and we are trying to build it with the same NULL_OS option but getting build errors - 2 of 34 pasted below:

Now having looked at the main file phExDoorAccess.c, it looks like this particular project doesn't support NULL_OS option?

 

 

Please could we get a confirmation if that is the case. Our application demands use of LPCD and there around 20uA average idle current from the device when in LPCD..

 

Thanks
