nRF51 IoT SDK only support KEIL MDK4?

[Paul]

I just downloaded the IoT SDK, found that they are KEIL MDK4 projects. When will the MDK5 softpack be available?

[Stian Røed Hafskjold]

The nRF51 device support for MDK5 is already available as a software pack. KEIL uVision version 5.12 or later does not support .uvproj projects anymore, but uses .uvprojx projects instead. If you want to continue working with .uvproj formats, you must install MDK Version 5 Legacy Support.

The IoT SDK project files will be released as Keil MDK 5 projects (.uvprojx) in the next offical release (march/april). Until then, you must use Legacy Support in Keil 5.12

Compiling using the legacy support seems to create hex files larger than 160KB
