Let me start off by saying that I'm not sure if this is the right place to ask, and I should also mention that I don't have much experience with ARM architecture or cross-compilation. I'm hoping someone here can help clarify a few things for me or point me in the right direction.
I'm working on compiling Google’s liblc3 library for a Cortex-M33 target. I’m using the latest version of arm-none-eabi-gcc (gcc version 9.2.1 20191025) and compiling with the -mcpu=cortex-m33 flag. However, the linker fails with the following errors:
arm-none-eabi-gcc
-mcpu=cortex-m33
To troubleshoot, we tested the compilation process for Cortex-M3 and Cortex-M4 targets, where everything works fine. The only significant difference I know of is that M3/M4 are Armv7-M, while M33 is Armv8-M. I've also checked each object file with arm-none-eabi-readelf, and they appear identical across all generated objects.
arm-none-eabi-readelf
Has anyone encountered similar linker errors when targeting the Cortex-M33 or switching from Armv7-M to Armv8-M? I suspect the issue lies with the library I'm trying to compile, rather than with the compiler itself. I’d appreciate any insights or suggestions on resolving this!
