Tool/software: Linux
Hi,
I'm trying to load DSP firmware from Linux where the DSP memory uses L2RAM/IRAM for it's memory locations.
If the memory is placed into DDR it will work, but if any memory is placed within the L2RAM then remoteproc.0 won't load the firmware.
Here is my config.bld
/*
* ======== config.bld ========
*
*/
var Build = xdc.useModule('xdc.bld.BuildEnvironment');
var Pkg = xdc.useModule('xdc.bld.PackageContents');
/* when constructing a release, release everything */
Pkg.attrs.exportAll = true;
/* Uncomment this to build the app with debug support */
Pkg.attrs.profile = "debug";
/* bin/ is a generated directory that 'xdc clean' should remove */
Pkg.generatedFiles.$add("bin/");
Build.platformTable["ti.platforms.evmOMAPL138:dsp"] = {
externalMemoryMap: [
[ "DDR", {
name: "DDR", space: "code/data", access: "RWX",
base: 0xC3100000, len: 0x800000,
comment: "DSP Program Memory (8 MB)"
}]
],
codeMemory: "DDR",
dataMemory: "DDR",
stackMemory: "DDR",
l1DMode: "32k",
l1PMode: "32k",
l2Mode: "0k"
};
/*
* ======== ti.targets.elf.C674 ========
*/
var C674 = xdc.useModule('ti.targets.elf.C674');
C674.ccOpts.suffix += " -mi10 -mo ";
Settings any of the Memory regions to be in the IRAM doesn't work when trying to load the firmware.
Address of the IRAM is 0x18000000 and the size is 0x40000
I have tried the following:
1. Tried adding DEVMEM to the resource table.
{
TYPE_DEVMEM, IRAM_DA, IRAM_DA, IRAM_SIZE, 0, 0, "DSP_IRAM",
},
2. Adding a memory pool to the DTS and making a carveout instead in the resource table
reserved-memory {
#address-cells = <1>;
#size-cells = <1>;
ranges;
dsp_memory_region: dsp-memory@c3000000 {
compatible = "shared-dma-pool";
reg = <0xc3000000 0x1000000>;
reusable;
status = "okay";
};
dsp_memory_region2: dsp-iram@18000000 {
compatible = "shared-dma-pool";
reg = <0x18000000 0x00040000>;
reusable;
status = "okay";
};
};
{
TYPE_CARVEOUT, IRAM_DA, IRAM_DA, IRAM_SIZE, 0, 0, "DSP_IRAM",
},
None of this worked.
I need my DSP memory to reside in IRAM/L2RAM.
Here is the full resource table:

Declaring either the IRAM as a CARVEOUT or as a DEVMEM did not fix my issue.
