MCUXpresso SDK and Keil MDK

Hi guys,


I've just picked up the eval board for the i.MX RT1052 and see that I have two options with Keil MDK:

  1. Start and manage a project using the CMSIS packs installed from within Keil that equate to MCUXpresso SDK v2.3.0.
  2. Go to and generate an MCUXpresso SDK v2.4.2 package targeted at Keil MDK.


My questions are:

  1. The CMSIS packs are lagging behind the generated SDK by about 5 months, are these being actively maintained?
  2. What are the advantages of using one approach over another? Instinctively I like the idea of managing everything in CMSIS packs but am also troubled by the version lag.
  3. What is the recommended approach to setting-up a project in Keil if I chose to use the generated SDK? (how do I import the files, what do I have to add to my project etc).


Any advise/help very much appreciated!


Many thanks
