Hi Hari, How can I map the address? At what part do I specify these mappings; bridge installation, at DSP side program (with the tci file etc.)? By the way just before that in the program I do a malloc(32) to another short pointer but |it doesn't return any errors?
Please forgive me if this is a trivial question but I'm just learning the DSP programming. Thanks a lot.
