Part Number: C2000WARE

Tool/software: Code Composer Studio

Hello,

I am trying to test ECC functionality by introducing bit errors through Code composer Studio.

In CS Studio I am using introduce bit errors option in Linker Output to generate bit errors.

1. As per the Syntax --ecc:data_error=(symbol+offset|address)[,page],bitmask I have given the location address ( --ecc:data_error=(test_variable+0|0x80000)[,0],1 ) to generate errors but I got below error.

Error 255 and Error 2 with message '0x80000)[' is not recognized as an internal or external command

2. when i give 0x80000,0,1 to generate error at 80000 location i got below error.

error specified at 0x80000 does not lie within an initialized section.

I tried with all the addresses mentioned in the linker command file, but still i am facing above error.

Flash ecc is enabled in my software.

Kindly let me know how to solve above issue.

Let me know if more details required.

Thank you.

Regards,

Bhageerath.

In the syntax description the characters (), [], and | are all descriptive. Do not use them when writing the option parameters.

The word address 0x80000 on page 0 must exist, and correspond to an initialized section like .text. Check the linker map file. My guess is that it exists on page 1, but not page 0.

Thanks and regards,

Hi George,

The address 0x80000 exists on page 0, so i tried with giving input as 0x80000,0,1 but still getting the same error.

Error message :: error specified at 0x80000 does not lie within an initialized section.

I checked the .text section in map file, I found .text.1 section (its on page 0) and respective address is given in introduce bit error section.

input : 0x080000,0,1
error : error specified at 0x8217c does not lie within an ECC input or output range null: error specified at 0x8217c does not lie within an ECC input or output range

Thank you.

Unfortunately, I am unable to reproduce the problem. Please submit the linker command file, and a resulting linker map file. Put them together in one zip file and attach that to your next post.

Thanks and regards,

Unfortunately, that is not the case. Your linker map file shows ...

MEMORY CONFIGURATION

         name            origin    length      used     unused   attr    fill
----------------------  --------  ---------  --------  --------  ----  --------
PAGE 0:
  RAMM0                 000000f5   0000030b  00000000  0000030b  RWIX
  RAMLS0_2              00008000   00001800  00000000  00001800  RWIX
  RAMLS3                00009800   00000800  00000000  00000800  RWIX
  RAMLS4                0000a000   00000800  00000004  000007fc  RWIX
  BOOTLOADERVERSION     00081fff   00000001  00000000  00000001  RWIX
  BEGIN                 00082000   00000002  00000002  00000000  RWIX

This means the addresses 0xa005 to 0x81ffe are not used.

Therefore, the linker is correct to say "0x80000 does not lie within an initialized section".

Thanks and regards,
