All, I'm using the objcopy utility for ARM to convert a binary file into an object file to be linked into a system build and I'm running into an issue that I hope someone can help with. The issue is that the resulting object file is in the ARM EABI 0 format instead of the ARM EABI 5 format required by the linking process.
Some details: - The tool chain used is built for RTEMS similar to http://www.rtems.org/wiki/index.php/Building_Tools - The version of binutils used is 2.24 - The target microcontroller is a Cortex-M4, thus it uses the "armv7-m" architecture and as I understand it must use the EABI 5 format The command used to convert the binary file to an object file is: arm-rtems4.11-objcopy -I binary -B arm -O elf32-littlearm <input-binary-file>.bin <output-object-file>.o This operation appears to work in that the <outputfile>.o file is created. When the linker attempts to build the elf file I receive the following error: ld: error: Source object <output-object-file>.o has EABI version 0, but target <output-elf-file>.elf has EABI version 5 The linker is actually called via a call to "arm-rtems4.11-g++" with numerous options and *.o files and such. The only significant options I see that are related to this issue are "-march=armv7-m -mthumb". I've tried a number of different approaches but haven't hit on a winning combination. My question is if there is an existing means to perform the appropriate binary to ARM EABI 5 object file conversion or whether this support is just missing from the current utilities? FYI, we used this same sort of binary to object conversion (via objcopy) on a prior non-ARM architecture and it worked fine. Regards, Steve. CONFIDENTIALITY STATEMENT.
