General memory map / memory partition question

Pierre-Olivier Belzile

Looking at the leatest EzSDK faq (http://processors.wiki.ti.com/index.php/EZ_SDK_FAQ), we can see what is the default 1GB memory partition. I understand how to configure linux memory allocation but what about the ~400MB reserved memory? What happen if I need to reduce the total memory to 512 MB?

It also appear that about 300MB is "Reserved-Multimedia specific". What if I only use only one VICP and no capture/3d rendering/display capacity, can I reduce this section ? Can we remap it below 512 MB?

I'm sorry if it has been answered before, but I can't find complete and detailed information on memory partition.

Regards,

P-O

    The memory map is fixed up to the most recent EZSDK (5.01.01.80) as per the release notes. This is a massive pain also for those of us who wish to make use of the entire 2GB of memory that the EVM has. Apparently this will be made "dynamic" in future releases. The "reserved" memory is used by the H264 codecs.
