RTX support in the nRF52 SDK

[Mike Voytovich]

Hi,

Does anyone know if there are plans to support RTX in the nRF52 SDK? It is included in the nRF51 SDK under external/rtx, and there is an example in examples/peripheral/blinky_rtx. However the nRF52 has no such files or directories.

I am not an expert in RTX, I did this and it worked for nRF52 RTX. I just copied blinky RTX example into nRF52_SDK.0.9.0\examples\peripheral\blinky_rtx

1) Target options ->Device ->selected nRF52 from the drop down and selected the nRF52832_xxAA
2) C/C++ tab -> __HEAP_SIZE=0 __STACK_SIZE=1024 BSP_DEFINES_ONLY BOARD_PCA10036 RTX NRF52
3)same as above for Asm tab
4) removed two files from Third Party Project folders and added these two from the path
C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS_RTX\LIB\ARM\RTX_CM4.lib
C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Pack\Example\Boards\Keil\MCB1800\RTX_Blinky\RTE\CMSIS\RTX_Conf_CM.c

I compiled the project, flashed to nRF52 board and it seemed to work. Looks like the support is already there from CMSIS :)

Yes. Clears that up. I'm a little bummed Nordic isn't going to release CMSIS packs as I find it terribly convenient, but I get that has nothing to do with the topic at hand.
