Review Comment:
Just using chdir doesn't solve the problem,
Because its problem is how to provide a fixed path as the starting search
location.
chdir still uses $CWD as the starting path, and the results of executing
nuttx in different paths are still different.
So we need to get the folder where the nuttx file is located as the starting
path
