Original question:
Hi everyone,
I'm trying to use arm compiler 9.3.1 for TMS570LC43 board but the compiling doesn't successful since the arm compiler 9.3.1 libraries are compiled in LE.
If anyone can help me out it would be so appreciated.
Below the error logs:
C:/ti/ccs1011/ccs/tools/compiler/gcc-arm-none-eabi-9-2020-q2-update-win32/bin/arm-none-eabi-gcc-9.3.1.exe" -mfpu=vfpv3-d16 -O2 -g -gdwarf-3 -gstrict-dwarf -Wall -specs="nosys.specs" -mbig-endian -mcpu=cortex-r5 -Wl,-Map,"TMS570LC4357_GCC_Example.map" -mcpu=cortex-r5 -mfpu=vfpv3-d16 -mfloat-abi=hard -mbig-endian -o"TMS570LC4357_GCC_Example.out" ...............ect.

I saw your solution about GCC ARM 7.2.1 that works in my project but I would need the same solution for GCC ARM 9.3.1.
OK, I have applied a patch to GCC ARM 9.3.1 to add big-endian support.
The output from generating the patched compiler is on my google drive gcc-arm-none-eabi-7-2020-q2-update
This includes the updated source, along with Windows and Linux executables.
I changed the version number to 9.3.1p1 to make it clear it is a modified version, rather than the standard version installed by CCS. If you install it in the CCS ccs/tools/compiler directory it should be discovered by CCS and be able to selected in a project as Compiler Version "GNU v9.3.1p1":
Attached is a CCS 10 example project for a TMS570LC4357 which uses HALCoGen 04.07.01 and the patched compiler, which is set to use hardware floating point.
As well as the selection of the patched compiler version, the important project selections to get big-endian BE32 support in v9.3.1p1 are:
Under Build -> GNU -> Compiler -> Runtime set:
Under Build -> GNU -> Compiler -> Miscellaneous add the following to Miscellaneous flags:
Under Build -> GNU Linker -> Miscellaneous add the following to Miscellaneous flags:
The -mbe32 option was found to be required to get the v9.3.1p1 compiler to get the correct endianness in the executable, since the newer compiler defaults to BE8. Whereas the previous v7.2.1p1 compiler didn't have the -mbe8 / -mbe32 options.
