AM5706: ICSS EMAC

Hi Expert,

I have two question on rebuild ICSS_EMAC in Linux User space

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_PRU-ICSS_PRU_ICSSG.html#icss-emac

1. When need to modify the source code of the ICSS_EMAC LLD and unit test, why we need use Linux SDK to compile it?  Can we use RTOS SDK to compile the PRU unit test, then generate the *.out file which can be put as PRU image in Linux file system?

2. If we re-build the icss-emac-lld and icss-emac-lld-test for AM57x, where to put RTOS source code in Linux SDK folders?

Thanks!
