Tool/software: TI C/C++ Compiler
Hi,
I have a TMS320C6748 custom board with a 256 DDR.
I made a custom memory map and currently having a problem with booting. But, it works well in simulation mode. Only troubles with flash boot. flash boot doesn't work.
I have applied some extreme values for testing purpose. mem size will be reduced in the real session. This is due to compiling USB driver.
[at the end of .cfg file]
Program.sectMap[".bss:extMemCache:ramdisk"] = new Program.SectionSpec();
Program.sectMap[".bss:extMemCache:ramdisk"].loadSegment = "APP_CACHED_BIOS_RSVD_MEM";
Program.sectMap[".bss:extMemCache:ramdisk"].type = "NOLOAD"
[local .cmd file]

What am I doing wrong here?
