assembly - Issue Cross Compiling FreeRTOS program for ARM

Question

I want to build FreeRTOS executables for my target which is a beaglebone black that has a AM335X ARM Cortex-A8 processor. I am running windows but i am using a virtual machine that runs linux debian 10 which is what i am cross compiling from. uname -a provides:

Linux debian 4.19.0-13-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux

I'm new to FreeRTOS so let me know if im going about this the wrong way. My plans is to write a FreeRtos program with C and and cross compile it and simply send over the executable to the beaglebone and run the executable. I tried this with a Hello world program succesfully so i figured it should be possible with a FreeRTOS program. I want to get this working on two different compilers since i want to test out both. The first one is arm-linux-gnueabihf-gcc and the second one is a bare metal version called gcc-arm-8.2-2019.01-x86_64-arm-eabi. My project can be found here: https://github.com/frank2597/FreeRTOS_BBB.git and as a shortcut my compiler option settings can be found in these two files:

https://github.com/frank2597/FreeRTOS_BBB/blob/master/source/CMakeLists.txt

https://github.com/frank2597/FreeRTOS_BBB/blob/master/source/toolchain.cmake

I am using Cmake to generate the makefile.Both cross compilers have troubles compiling with my testing.c freertos program. When i use the arm-linux-gnueabihf-gcc compiler i get various warnings and some undefined references but the compiler reaches 100%, the errors from the make command is presented below (cant post verbose output due to character limit):
