Kboot 1.2.0 and OSX 10.11.2

Question asked by Da Gau on Dec 27, 2015



I have some problems loading applications on my FRDM-K22F board using Kinetis Bootloader 1.2.0 on Mac OSX 10.11.2. I have followed the instructions from the “Kinetis Bootloader Demo Application User’s Guide” and successfully built the Xcode version of the blhost utility but having problems issuing commands to the bootloader. For instance, the blhost utility hangs (never returns) when issuing the command “blhost -p /dev/tty.usbmodem1422 — get-property 1” as stated in the user’s guide (step #4).  Any pointers on getting this issue fixed would be greatly appreciated.


Here’s some info of my setup:


FRDM-K22F Firmware version: 0221 —

Bootlaoder version: Kinetis Bootloader 1.2.0

OS version: OSX 10.11.2


Many thanks!
