[Icc-avr] Placing text in an absolute locations in the AT90CAN128 Boot Loader?

[Milender, Jeff]

I'm having difficulty with the same problem I resolved yesterday but now
in Boot Code. (Compiler Options/ Program Type / Boot Loader)
 
I assumed that I would use the same approach as with the Application
code, the compiler does not complain about this approach but it also
does not utilize "mytext" defined area.
 
Is there something different I will have to do to place things in
absolute locations in Boot Code? (Compiler Options/ Program Type / Boot
Loader)
 
I would expect to see BOOT_CHECKSUM_VALUE located at 0x01e100 but the
MAP files shows it at 0x1E136  
 
Same with BOOT_CRC_VALUE; expect 0x01e102 map shows 1E138 and so on.
 
 
C Source
// ---------------------------------------------------- //
// START - FLASH Assignment of Absolute Addresses       //
// ---------------------------------------------------- //
#pragma text:mytext
const INT16U BOOT_CHECKSUM_VALUE = 0x01234;
const INT16U BOOT_CRC_VALUE = 0x0ABCD; 
const INT32U BOOT_END_ADDRESS = 0x01FFFF;
const INT8U BootCodeSWPartNumber[21] =  {"787S005-004"};
#pragma text:text

Yup, this will work, since the -bfunc_lit you 
added effectively overrides the one from the IDE.
