Andes Method of transforming sag to ld file

1. Enter ‘cygwin’ through ‘D:\Tools\Andestech\AndeSight_STD_v510\toolchains\nds32le-elf-mculib-v5\cygwin-andes.bat’

2. Enter ‘D:\Tools\Andestech\AndeSight_STD_v510\utils’, Put the sag file in this directory

Execute the following command in the cygwin environment:

nds_ldsag.exe --version=v5 -t ./nds32_template_v5.txt bk7237_bsp.sag -o bk7237_bsp.ld
