Forum Post: RE: MPAX Initialization

Hi Eric,

I have read section 2.2 about MPAX so I know what values I want to put into the registers. I have also created a small test program that is loaded purly into L2SRAM to verify the MPAX register configuration. In this test program I have created a function which configures the MPAX registers. This all works fine when everything is in L2SRAM, the problem comes when you create a dsp image where everything is loaded into DDR3B memory.

When everything is loaded into DDR3B memory even the ELF entry point, then I need to configure the MPAX register even before the DSP reaches the entry point. Is this possible?

Or do I have to make sure that the entry point is always loaded in L2SRAM and somehow run my MPAX configuration function before jumping to the rest of the code which is located in DDR3B?
