If you check the original linker scripts, you will notice that the shared memory area is 32 MB in size and divided in two parts. The first part is reserved for the C library and other stuff, the second part is reserved for the heap.
If you do not use the heap on the Epiphany cores, you can use the upper half of shared memory freely (offset 0x00100000).
If you do not use functions from the C library on the Epiphany cores, you can use the lower half of shared memory freely (offset 0).
