EVMK2H PROCESSOR-SDK-LINUX-RT vs PROCESSOR-SDK-RTOS

So far I understood that PROCESSOR-SDK-LINUX is only for ARM (no DSP) and Linux OS host (right?)

The  both PROCESSOR-SDK-LINUX and  PROCESSOR-SDK-LINUX-RT is for ARM running linux.  Only Linux OS host(.bin) binary installer is available for this.

my question is between the other 2. What is the difference ? by RTOS in PROCESSOR-SDK-RTOS you mean Ti-RTOS ?

Yes. The PROCESSOR-SDK-RTOS is for ARM & DSP running TI-RTOS(SYS/BIOS). It has two installers wrt host (Windows(.exe) and linux(.bin).
