AM5728: DSP direct access to DDR

chen chen35

Part Number: AM5728

I used AM5728 now. When I see the interconnect overview,he DDR interface directly connected to the ARM, and the DSP connection is separated by a DMM ,Please help confirm whether DSP can access DDR3 directly? what should I do? thanks.

Hi,

Yes, it can. What software are you running on the DSP?

Why can't I access DDR through DSP?I'm using ccs7.

I can access OCMC_RAM1 but cannot access DDR.

DMM Settings are as follows:

static const struct dmm_lisa_map_regs beagle_x15_lisa_regs = {
.dmm_lisa_map_3 = 0x80740300,
.is_ma_present = 0x1
};
