board_build.f_cpu = 72000000L

[Ozzie_G]

Dear all,

I have been using platformio with the Teensy for about a year now, and the -.ini file of all my projects included

board_build.f_cpu = 72000000L

(or other speeds that are available for the Teensy the project uses)
I am sure i have copied that line from some manual when i started to use the 'platform'
update: yes, got it from here.
https://docs.platformio.org/en/latest/boards/teensy/teensy31.html



Since the previous update, this line creates the error:

Error : This board doesn't support board_build.f_cpu = framework!


Where does this come from? Where do i set the required cpu speed in the current situation, or what is the default if i don't set it ?



Thanks.
