CCS/TMS320F28335: TMS320F28335

I have connected the ADC to sensor OUT put. how ever the variabls in the expression ware still not vary. Is the follwing warnings be the cause? some of the memeory error were solved as follwing your direction in the previous. however, the below could not fix.


PAGE 1 :
/* BOOT_RSVD is used by the boot ROM for stack. */
/* This section is only reserved to keep the BOOT ROM from */
/* corrupting this area during the debug process */

BOOT_RSVD : origin = 0x000002, length = 0x00004E /* Part of M0, BOOT rom will use this for stack */

how can i fix these warng? would apprciate some guide for this problem. thank you

Hi,

Please update your linker command file to include the sections mentioned in the warnings. I see sections .cntlcoeff, .cntlar present in the cmd file file. Probably, in your source code where you define those sections, "." may not be present. Please keep the names consistent in both yor source code and linker command file.

Yes , you are right, I do not use dot '.' in pragma section. i define as follows:

// FILTER EXTRACTION
#pragma DATA_SECTION(cntl2p2z_BPFICF_vars,"cntlar")
#pragma DATA_SECTION(cntl2p2z_BPFICF_coeff,"cntlcoeff")
CNTL_2P2Z_F_VARS cntl2p2z_BPFICF_vars;
CNTL_2P2Z_F_COEFFS cntl2p2z_BPFICF_coeff;



one thing i want to tell you that i use

'28335_RAM_lnk.cmd' file in the project folder

in c2000 linker -> file serch path
C:\ti\controlSUITE\..\DSP2833x_Headers_nonBIOS.cmd



project -> linker command file : 28335_RAM_lnk.cmd

Is these two files should be the same i.e. either '28335_RAM_lnk.cmd' or 'DSP2833x_Headers_nonBIOS.cmd'?


and finally I tried to add dot '.' in my code as shown below
...
#pragma DATA_SECTION(cntl2p2z_BPFICF_vars,".cntlar")
...


but nothing was changed . I tried to search how to 'update linker command file to include the sections ' Could you tell me the steps please. thanks
