Hello! I think that toochain documentation is very important to follow, I have a problem, in the step . /usr/local/openmoko/arm/setup-env, this document or file is not found, but I found ./usr/local/openmoko/arm/environment-setup can I use ./usr/local/openmoko/arm/environment-setup instead of . /usr/local/openmoko/arm/setup-env, or what to do?? thank you
