The LED blinking works perfectly fine, but when I monitor the console output, the words "Hello World are only printed 4 to 5 times. This kind of simple printing works perfectly fine with the standard teensyduino install. I am running FreeRTOS v10.0.1, but i have replicated this issue on v9.0.0 as well

Any help would be appreciated!

Hello Jacob. I am new to the Teensy3.6 and I am interested using your FreeRTOS port with PlatformIO in OS X. I have a project created and incorporated your files. I crated a FreeRTOS folder in the src directory and copied all the FreeRTOS files into the folder using a flat structure. I used the portable/GCC/ARM_CM4_MPU port.c and portmacro.h files. Not sure if this is correct set of files to use.

I managed to get it to compile but I am getting a few errors. Do you see something that I am missing? Thanks for the help.

It seems like the only reason we can't increase the tick frequency is because of systick_millis_count. Is that what you found as well? Have you tried modifying the systick_millis_count to increment off higher rates or pointing FreeRTOS to a different timer? Thanks!
