# PRU_CGT environment variable must point to the TI PRU code gen tools directory. E.g.:
#(Desktop Linux) export PRU_CGT=/path/to/pru/code/gen/tools/ti-cgt-pru_2.1.2
#(Windows) set PRU_CGT=C:/path/to/pru/code/gen/tools/ti-cgt-pru_2.1.2
#(ARM Linux*) export PRU_CGT=/usr/share/ti/cgt-pru
#
# *ARM Linux also needs to create a symbolic link to the /usr/bin/ directory in
# order to use the same Makefile
#(ARM Linux) ln -s /usr/bin/ /usr/share/ti/cgt-pru/bin
