Compiler/TMS570LS3137: arm-none-eabi-gcc compile error

Tool/software: TI C/C++ Compiler

I use HALCOGEN to generate code with GCC Tools,and use arm-none-eabi-gcc to compile the code on linux,the makefile reported compile error:

arm-none-eabi-ld -n -o boot.elf ./bin/*.o ./bin/*.a -L/usr/bin/gcc-arm-none-eabi-9-2019-q4-major/arm-none-eabi/lib
