libbgcommon.a: file format not recognized; treating as linker script, reinstall sdk:https://github.com/SiliconLabs/simplicity_sdk/releases

[delayzzz]

if i download .zip sdk file, and unzip and add sdk in studio v5, error emerge while building (protocol/bluetooth/bgcommon/lib/build/gcc/cortex-m33/bgcommon/release/libbgcommon.a: file format not recognized; treating as linker script
protocol/bluetooth/bgcommon/lib/build/gcc/cortex-m33/bgcommon/release/libbgcommon.a:1: syntax error)

i may got the solution, install git and git-lfs, then using "git lfs clone https: ..." to download the simplicity sdk repo(you may need to set the git proxy port to align system global proxy), finally add sdk in studio v5 preference window, and it work. (build without error)
