One is an ARM processor running linux and another is a non-ARM processor running linux operating system (Proprietary Proc). We do not have any medium like Network Interface or PCI or USB running between the two processors, except 1GB of shared memory. We would want to be able to SSH the non-ARM processor on the ARM processor and mount FS. I was wondering if I can get some suggestion on what would be a possible way to establish this communication between the processors. As a matter of concept, I just happen to write a small network driver that talks over the shared memory and could transfer packets between the two. But this does not help me with my bigger use case of being able to SSH one processor from the other. Greatly appreciate any suggestion in this regard. Thanks
