Hi All,
I would like to access the SDRAM (or IRAM) on the DSP side of OMAP
1510.
There is code on TI website for OMAP 5910 for configuring the DSP MMU
to map the 32 bit addresses to the 24 bit addresses on DSP side.
(The physical addresses for SDRAM (or say IRAM) are the same for both
OMAPs)
http://focus.ti.com/docs/apps/catalog/resources/appnoteabstract.jhtml?
abstractName=swpa038
However When I try to access the SDRAM or IRAM on the DSP side, CCS
gives a memory access error. I can access them properly on the ARM
side using their physical memory addresses directly.
Has anyone faced this problem before ?
Why is this happening ?
Are there some other things that I need to configure too ?
Help is most appreciated.
thanks in advance,
rmb
