Compiler/TMS320F280049C: Testing ECC Data_Error

Sandeep,

What is the address where you want to include ECC error when you configure  --ecc:data_error=0xC1F2+1,0x42 ?

Thanks and regards,
Vamsi

I thought "const Uint16 SoftwareVersion = 0x0300;" is allocated in .econst which goes into section "FLASH_BANK0_HALF1". But address in map file is showing for "SoftwareVersion" is 0xC1F2. How can I pick a const variable in FLASH_BANK0_HALF1 to introduce ecc:data_error?

-----------------------------------------------------------------------------------------------------------------------------------------------

Now, I changed in linker file as below to place 'SoftwareVersion' in FLASH_BANK0_HALF1.

.econst          : > FLASH_BANK0_HALF1, PAGE = 0, PALIGN(4)

Now, map file shows:

page   address          name

0        0008105e      _SoftwareVersion
