I want to load the out file into DSP using MPMCL in linux.
I put the code in DDR(DDR3_DSP_CODE) as shown below. (I used 2GB DDR memory)

And I modified the evm.dts file
form
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
dsp_common_memory: dsp-common-memory@81d000000 {
compatible = "ti,keystone-dsp-mem-pool";
reg = <0x00000008 0x1d000000 0x00000000 0x2800000>;
reusable;
status = "okay";
};
dsp_common_memory: dsp-common-memory@81f800000 {
compatible = "shared-dma-pool";
reg = <0x00000008 0x1f800000 0x00000000 0x800000>;
reusable;
status = "okay";
};
};
to
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
dsp_common_mpm_memory: dsp-common-mpm-memory@a00000000 {
compatible = "ti,keystone-dsp-mem-pool";
reg = <0x0000000A 0x00000000 0x00000000 0x10000000>;
no-map;
status = "okay";
};
dsp_common_memory: dsp-common-memory@b0000000 {
compatible = "shared-dma-pool";
reg = <0x0000000b 0x00000000 0x00000000 0x50000000>;
reusable;
status = "okay";
};
};
but occurs error -104 when mpmcl load.
ex
:~# mpmcl reset dsp0
reset succeeded
:~# mpmcl load dsp0 thunderDSP.out
load failed (error: -104)

Is there anything else I need to do ? or Did I correct it wrong?
Thanks,
