Lack of support for Nordic nRF51822

I note that including this library causes grief when trying to compile for Nordic nRF51822 platform in RTX_Conf_CTM.h as the platform defines appear to be missing.

Is this platform expected to be supported?

Can we have the define values for:

OS_TASKCNT OS_SCHEDULERSTKSIZE OS_CLOCK

Question relating to:

Last updated: 04 Jul 2017
Official mbed Real Time Operating System based on the RTX implementation of the CMSIS-RTOS API open standard. cmsis, rtos, RTX

Is this scheduled to work anytime soon?

Hello Jerod Klink,

we look into this, report back once it gets its support . Thanks for reporting.

One addition, please use less generic headline, RTOS support for NRF for example would be much more descriptive.

Any idea when this is scheduled for?

There's pull request to add also GCC for nordic target, along with RTOS. Once GCC will be fully functional, it will be accepted.

Could I understand the schedule/timeline for this to happen? It's imperative to know whether this is working in a few weeks or a few months; design decisions/tooling need to be made. Thanks.

RTOS support should be added soon, it's ready as I saw it in the pull request, but the problematic is gcc exporter which is currently not working. I can advise to split that pul lrequest into two, so RTOS support gets in.

What is the status of this? I am currently able to build the "Hello World" app, but it appears to be crashing (it lights the leds, but they don't blink).

In offline mode, using gcc, I get:

ToolException: /usr/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld: region RAM overflowed with stack

Any suggestions?

@Brian, hello world RTOS app? Does it crash in the online IDE? What's the revision of mbed lib? Using beta or normal mode? Without further details, nobody will be able to help you.

Sorry it took so long to get back to this. I got side tracked on another project...

If I just import this program: http://mbed.org/teams/mbed/code/rtos_basic/ and compile for the nRF51822 it lights both LEDs and that's it, they don't blink.

I've been unable to get any nRF51822 program to run on the offline SDK using gcc, but I think that's a known problem.
