Demos pins for M4F core

Default M4F pins used by the demos are:

Function	SoC balls	VAR-SOM-AM62 pins	Symphony pins	Notes
UART2 RXD/TXD	R24/R25	J1.115/J1.171	J18.9 / J18.7	The UART2 is not an instance from the MCU domain so only the polling mode is supported. To more details: Accessing main and wakeup domain peripherals from MCU domain Don't use /dev/ttyS2 from linux while running M4F examples to avoid conflicts.

Building a demo

Building hello_world for MCU M4F

$ cd ~/mcu-plus-sdk-am62x
$ export PROJDIR=examples/hello_world/var-som-am62/m4fss0-0_freertos/ti-arm-clang/
$ make -s help
$ make -s -C ${PROJDIR} clean
$ make -s -C ${PROJDIR}
This produce the M4F binary ${PROJDIR}/am62-mcu-m4f0_0-fw for RTOS OS

To build for NO RTOS use:
$ export PROJDIR=examples/hello_world/var-som-am62/m4fss0-0_nortos/ti-arm-clang/

Building hello_world for WKUP R5F (DM R5)

$ cd ~/mcu-plus-sdk-am62x
$ export PROJDIR=examples/hello_world/var-som-am62/r5fss0-0_freertos/ti-arm-clang/
$ make -s help
$ make -s -C ${PROJDIR} clean
$ make -s -C ${PROJDIR}
This produce the R5F binary ${PROJDIR}/am62-wkup-r5f0_0-fw for RTOS OS

To build for NO RTOS use:
$ The hello_world NO RTOS is not available for R5F core
