I am working on course project to do encryption and decryption with the Teensy (3.6). I referred to https://forum.pjrc.com/threads/34808-K66-Beta-Test?p=108621&viewfull=1#post108621. where there are guideline for crpto operations with the Teensy IDE.
I did the following steps
cp lib_mmcau.a hardware/tools/arm/arm-none-eabi/lib/libcau.a
in boards.txt change to
teensy36.build.flags.libs=-larm_cortexM4lf_math -lm -lcau
teensy35.build.flags.libs=-larm_cortexM4lf_math -lm -lcau
and then tired to run the test file "crypto.ino" that I could find online https://github.com/manitou48/teensy3/blob/master/cryptolib.ino
But when I run it I get the following error c:/program files (x86)/arduino/hardware/tools/arm/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld.exe: cannot find -lcau . ( also attached a screenshot of the output error)
It does not like the flag lcau that I added in the boards.txt file. Can you tell me what I am doing wrong here ?
