Parallella Community

Is it a good idea to try to change the 32MB shared DRAM limit [0x8e000000...0x8fffffff]? For instance, to expand it to [0x8CF08000...0x907FFFFF] (~57MB) as the E64 memory model seems to allow this. Then if I change and recompile the device tree file and update LDFs accordingly -- will it work? If yes, in principle it would be possible to use other parts of the memory address space that are not mapped onto cores. Could be very useful to have more shared memory in exchange for having less system memory. My Linux doesn't seem to use more than 100 out of 512 MB anyway.

Ivan,
Sorry for the slow response! Yes,this is certainly possible. I would not recommend running Ubuntu with less than 400MB of DRAM.(more is better). The zedboard only has 512MB. With the 1GB of the Parallella you will have more choices.
