Hi All,
I am using DAVINCI 6446 platform for a image processing algorithm. I want to use #pragma CODE_SECTION for putting a part of my code to L1PSRAM. When i tried to do this, i am getting a run time error on the target as..
Error: DSP-side memory map does not match configuration.
Compare DSP-side TCF/MAP file with /dsplink/config/all/CFG_<PLATFORM>.c
TraceUtil> Error: Failed to open codec engine "image_alog
TraceUtil> Error: Aborting TraceUtil_start
I tried to change the CACHE_L1P with default 32k to 16K or OK and make L1PSRAM 16K or 32K respectively. But when ever I try to change CACHE_L1P to L1PSRAM and put code into L1PSRAM, I am getting the above error. My configurations are as follows..
1. change in server .tci file. This makes L1PSRAM 32K or 16K
var device_regs = {
l1PMode: "0k", // "16K"
1DMode: "32k",
2Mode: "64k",
l1DHeapSize: 0x04000
};
2. Change in codec source code. To put exFunction in .exe_Sec section.
#pragma CODE_SECTION(exFunction, ".exe_Sec");
int exFunction()
{
}
3. Change in server link.cmd file. To put .ex_Sec to L1PSRAM.
SECTIONS {
.ex_Sec: > L1PSRAM
}
Query:
1. Why am I not able to put code to L1PSRAM?
2. Can I use L1PSRAM in DM6446 for putting code into it, or it can only be used as CACHE_L1P?
3. Is the procedure for using code section proper? Please suggest if there are are any changes.
4. Can we use IRAM for putting code into it? When i tried to do with IRAM also i am getting the same error as of L1PSRAM.
