TMS570LS1224: Unused memory fill with custom pattern- Compiler/Linker options

SACHIN BABYRAJAN

Hi ,

I have already set up the linker options fill value to my pattern,but no fill with the pattern is observed.

Also tried the compiler options of --image with ROM like in the example below,

:infile.out --image --memwidth 16 ROMS { EPROM1: org = 0x00004000, len = 0x2000, romwidth = 8 files = { rom4000.b0, rom4000.b1} EPROM2: org = 0x00006000, len = 0x2000, romwidth = 8, fill = 0xFF00FF00, files = { rom6000.b0, rom6000.b1} }

please help us with an example (.out file name is ISG.out)

My map file is like this:

name origin length used unused attr fill
---------------------- -------- --------- -------- -------- ---- --------
VECTORS 00020000 00000020 00000020 00000000 X
KERNEL 00020020 0000ffe0 00008464 00007b7c R X
FLASH0 00030000 00110000 00036b94 000d946c R X

I want to fill only the FLASHO unused memory part with 0XFF

Hi Sachin,

You can use "fill" option in linker cmd file to fill the memory with specified value. I filled the Flash01 (0xC0000~0x100000) with 0x5A5A5A5A:

If you specify fill values for large memory ranges, your output file will be very large because filling a memory range (even with 0s) causes raw data to be generated for all unallocated blocks of memory in the range.
