Issues with v7e-m libraries from arm-none-eabi-ld when building myevic

Hello all,

I'd like to upgrade my vape mod's firmware with myevic custom one from here: https://github.com/ClockSelect/myevic

I've been following the below instructions
- https://github.com/ClockSelect/myevic/b … uild_en.md
- https://github.com/ReservedField/evic-s … /README.md

and the exact commands I ran were as follows:

git clone https://github.com/OpenNuvoton/M451BSP.git
git clone https://github.com/ClockSelect/myevic.git
mkdir myevic/nuvoton-sdk
cp -r M451BSP/Library myevic/nuvoton-sdk
cd myevic
EVICSDK=. make

Upon running the make command I get the bellow output:

I should also mention that the below packages are installed as dependencies:

┌─[tsvetkov@anna] - [~/Documents/builds/evic_firmware/myevic] - [Sat Nov 07, 15:51]
└─[$] <git:(master*)> pacman -Q | grep "arm*.none*.eabi\|python-evic-git"

└─[$] <git:(master*)>

When I checked the /usr/arm-none-eabi path for the 4 libraries marked I get the below output. As you can see there is a nofp directory between the v7e-m and the libraries themselves. Additionally there isn't a libgcc.a library anywhere within the /usr/arm-none/eabi path.

That being said I'm quite lost now.. If anybody has experienced a similar issue with these packages and is aware of a solution or has an advice I'd greatly appreciate it. Let me know if additional information is needed as well

Thanks,
me
