Is there a special version of softdevice to use with softdevice

[Mahendra Tailor]

Hi

Can you please point me to some documentation which shows how to run SD140 with freertos on an 840 chip?

Look forward to hearing from you

Kind regards

Mahendra

Can you please quickly confirm, one way or the other, if exactly the same softdevice binary is used for non-rtos and rtos implementations?

 Yes, it's the same softdevice that it used.

And if same softdevice hex file, then which minimum version of softdevice is required?

 If you are using nRF5 SDK v.15.3.0, you should use the softdevice version that is listed under "Supported Softdevices" in the release notes. 
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/index.html?cp=5_1_0 

For nRF5 SDK v.15.3.0, this is: 

Supported SoftDevices:
 - S112 v6.1.x
 - S132 v6.1.x
 - S140 v6.1.x
 - S212 v6.1.x
 - S312 v6.1.x
 - S332 v6.1.x
 - S340 v6.1.x

When using the nRF52840, you would need the S140 v.6.1.x. 
Softdevice S140 v.6.1.1 is the version that is release with nRF5 SDK v.15.3.0 so I would suggest using that version.
