My next project is based on Kinetis EA series (Automotive grade cortex M0+) MCU. But it is not supported in KSDK v2 (https://kex.nxp.com/en/select ) I am also not able to find anything similar for it. The video shown in this page shows a program structure that I have never seen in ARM world (there were not startup code that even initialized the clocks sources, no CMSIS code, no interrupt handler files)
That confused me a lot. Please help.
