Anyone heard of mynewt OS? Opinions?

I've heard mention on here of FreeRTOS and ChibiOS.

I'm mostly interested in this for something like the nrf52.

Pardon that this isn't particularly teensy-related, but kinda.
 
Never heard of it.
Quick read... Unlikely something I'd need.

one bullet from the slide deck
Reduced code size: code often runs out of flash, and total available code size ranges from 64-128KB to 16-32MB.
 
It's worth looking at if you are working with nrf52. It has a fully open source Bluetooth Low Energy stack, down to the controller which is attractive. Unlike FreeRTOS adding various modules doesn't cost anything.
 
Not sure where you got the 16-32MB quote from, but if you run checks on the code size the kernel is ~5 KB and a fuller RTOS (without secure bootloader) with the BLE 4.2 stack is ~100 KB.
