TMS320F28069F: A question on the Linker Command File
Part Number: TMS320F28035
Tool/software: TI C/C++ Compiler
Can anyone help me to understand this linker file section?
progRAM : origin = 0x008000, length = 0x001400 /* on-chip RAM (L0-L2)*/ OTP : origin = 0x3D7800, length = 0x000400 /* on-chip OTP */ FLASHH : origin = 0x3E8000, length = 0x008000 /* on-chip FLASH */
/* Allocate program areas: */ /* Initalized sections go in Flash */ /* For SDFlash to program these, they must be allocated to page 0 */ .econst : > FLASHH PAGE = 0 .switch : > FLASHH PAGE = 0
/* Allocate IQ math areas: */ IQmath : > FLASHH PAGE = 0 /* Math Code */
.cinit : > FLASHH, PAGE = 0 .pinit : > FLASHH, PAGE = 0 //.text : > FLASHH, PAGE = 0 /*For CRC tables */ .TI.crctab : > APPCRC, PAGE=0 .text : > FLASHH, PAGE=0, crc_table(_linkerCRC,algorithm=CRC32_PRIME )
codestart : > BEGIN PAGE = 0 ramfuncs : LOAD = FLASHH, RUN = progRAM, LOAD_START(_RamfuncsLoadStart), LOAD_END(_RamfuncsLoadEnd), RUN_START(_RamfuncsRunStart), PAGE = 0
Here my entire code is in FLASHH. I defined .cinit., .init as part of the FLASHH.
I have some functions which need to be run from RAM. So I defined those as ramfuncs.
Is there anything wrong with this?
"ramfuncs : LOAD = FLASHH" what does this mean? Does it place entire FLASHH on ram?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Ozino Odharo:
What is wrong if I have .cinit and ramfuncs are in the same flash memory?
In reply to Patel:
I combined other sectors to form a big sector.
FLASHH : origin = 0x3E8000, length = 0x008000 /* on-chip FLASH */// FLASHG : origin = 0x3EA000, length = 0x002000 /* on-chip FLASH */// FLASHF : origin = 0x3EC000, length = 0x002000 /* on-chip FLASH */// FLASHE : origin = 0x3EE000, length = 0x002000 /* on-chip FLASH */
