SysBios - Relocation Compilation Errors

Hi,

I took asm & c code that worked with DSP/BIOS and tried to compile it with SYS/BIOS.

I got the below errors.

How can this be solved?

1) Temp1.c:

#pragma DATA_SECTION(CharArray, "TempSection")
char CharArray[4];

2) Temp2.asm,

.ref CharArray

lines 64-65:
MVKL CharArray & (~7), B1
MVKH CharArray & (~7), B1

3) cl6x -mv6740 --abi=eabi ./Temp2.asm

Output:

"./Temp2.asm", WARNING! at line 64: [W1500] warning: relocation template 275
not found; returning OFR_INVALID
MVKL _CharArray & (~7), B1

"./Temp2.asm", WARNING! at line 64: [W1500] warning: relocation template 276
not found; returning OFR_INVALID
MVKL _CharArray & (~7), B1

"./Temp2.asm", WARNING! at line 64: [W1500] warning: relocation template 267
not found; returning OFR_INVALID
MVKL _CharArray & (~7), B1

"./Temp2.asm", ERROR! at line 65: [E0200] Unable to resolve this relocatable
expression; relocation support for

available in the C6000 EABI
MVKH _CharArray & (~7), B1

Thanks,

Gilad,
the problem and the warnings and errors don't seem to be related to BIOS. You may want to move the thread (or post a new one) in the compiler forum. They'll probably want to know which compiler version you used when the code worked, and which one are you using now.

Expressions like "CharArray & (~7)", which cannot be evaluated by the assembler, are not supported for EABI. If it is impractical to build with the older COFF ABI, then you have to evaluate that expression at runtime.

Thanks and regards,

Try aligning CharArray with pragma DATA_ALIGN, and then you won't need to mask off the lower bits.
