I'm using Kinetis Design Studio 3.2.0.
I'm trying to use the lwIP library in my project, which consists of a Kinetis MK20 at 70MHz. For this, I've done some investigation and it seems that using a RTOS would enable some higher level functions of the library, such as opening sockets, which I believe will be needed for my application. To use the RTOS, I believe that I need to create a project with Kinetis SDK enabled.
Using the SDK builder at https://mcuxpresso.nxp.com/en/builder , I have found that the MK20 processor is available, but only the versions at 50MHz and 100MHz. Specifically, my processor ir MK20DX256VLL7, and it does not seem available for the SDK download.
My question is, is it possible to use the SDK from the 100MHz version and somehow adapt it to the 70MHz version?
