Hi, thanks for reply!
Two follow up questions:
Concerning "you may want to look at some of the DSPlink or syslink code" where could I see this code?
Concerning "opening "/dev/mem" and using mmap()": will I be able to read/write to any... Aviv Prital

Note if your writing your own bare-metal communication you may want to look at some of the DSPlink or syslink code as you'll need to do similar things as they do.
Talked with another engineer.

Thanks for the prompt reply!
I'm thinking about shared RAM that ARM user space linux driver will be able to mmap in order to write/read to DSP.
Thanks,

Could you provide more information on what is suitable for your project? Jonathan Cormier

AP 01:44 PM Software Development: Change data between ARM(Linux) - DSP (bare-metal)

Hi,
I'd like to use MityDSPL138 kit in order to develop ARM(Linux) - DSP (bare-metal) data exchange over shared memory.
As far as I understand TI's DSPLink/SYSLINK rely on RTOS at DSP which is not suitable in my case.
Is there any ex... Aviv Prital
