I just published a new port of the latest FreeRTOS version for the nRD51 SDK 8. Please see devzone.nordicsemi.com/.../ for details.

There is RTX RTOS port in nRF51-SDK already. Look at examples\peripheral\blinky_rtx which demonstrates RTX with plain nRF51822 and examples\ble_peripheral\ble_app_hrs_rtx which provides HRS example for S110 running on top of RTX. RTX port supports tickless mode which reduces power consumption.

There is a FreeRTOS port on GitHub. It's not a bad starting point. github.com/.../FreeRTOS8.0.1-nrf51-softdevice

Thank you.

I'm not sure I understand what you need to know. FreeRTOS uses SVC calls, and so does the softdevice. The softdevice does however not use all SVC numbers, and as detailed in the SDS, some are available for the application to use, for example by FreeRTOS.

AFAIK, softdevice used SVC, but I didn't know about freertos.

Does it OK?

Actually, the SoftDevice is not really an RTOS. It does not provide most of the infrastructure that goes with it, and it was designed to be RTOS agnostic. You should be able to run FreeRTOS on top of the SoftDevice.

This question seems to have slipped under the radar this fall. However, there is no official FreeRTOS port to nRF51822, but based on some quick internal experiments, we do think that it would be possible to do such port, even when using the softdevice. Some care may have to be taken with regard to RAM consumption, though.

There may be further activity on this some time this year, but I can't give any promises. If anyone does a port themselves, we'd be very interested to take a look on it, if they could share it.

If you look at the "Key Features" section of both the S110 and S120 soft device description pages they claim that they have "No RTOS dependency" and that "Any RTOS can be used"

Any possible to release a RTOS in mouths?

RE: FreeRTOS

It would be nice if nordic release a RTOS that works with BLE.

If you just wanted to natively use the radio with no SoftDevice, it should be a relatively easy port.

If you want to use it with the SoftDevice, you're going to be out-of-luck. Plus the SoftDevice is something of an RTOS in some respects.
