I have code here that gives errors when compiling it for the RedBoard but not for the Uno.
The errors I get are associated with TCCR0B, TCCR1B, and TCCR2B.
The code is from Infineon website for Low Side Switch Shield with BTF3050TE for Arduino, it is a Arduino development board using automotive Infineon MOSFET for applications.
