We are making a custom board based on Vertex7(Microblaze) & fmcomms5.
Our application requires us to port linux on it.
What are off-chip memories necessary for the purpose?
We need to boot linux each time on power-on and run out application.
So I believe we need a NOR-Flash for storing our linux elf file and a DDR3 for execution of kernel.
1:Sir, I want to ask are my assumptions correct?
2:Is there any other better way which serves the purpose?
3:In case we interface DDR3 and NOR-Flash can we disable the block-ram IP or does it serve some other purpose?
