Hi I'm liking the myNewt direction and thanks for the explanations, wiki and videos.
I've got a Nxp/Freescale Kinetis custom board with a MK26 (flash1M/ram200k 2*otg) KinetisK that is similar to MK64F on FRDM-MK64F I have a FRDM-MK64F board and also an olimex-H407 (same processor as olimex-E407 but no Ethernet). I have the newt tools brought into an Ubuntu 16.04 and run the sim_blinkey I was thinking of getting started with trying to bring up the FRDM-K64F, thought that is marked as untested so far. It does have the USB/SDA loader. myproj\repos\apache-mynewt-core\hw\bsp\frdm-k64f\src seems to have the basics. Alternatively, I could familiarize myself work through the Olimex-E407 My environment so far has been IDE Freescale Kinetis Design Studio/Eclipse building nuttx OS, and with integration to Multilink JTAG for blowing the flash. There was a new feature request for an Eclipse plugin for myNewt, but it was marked as dup, and I haven't seen any other mention of Eclipse IDE so far. Any recommendation on getting started with FRDM-K64F? or should I start with Olimex thanks -- Neil Hancock
