For some reasons I had to stop installation of JetPack TK1. I clicked “Cancel” at step 8.b. of the installation guide. (http://docs.nvidia.com/jetpack-tk1/index.html#developertools/mobile/jetpack_install.htm) Then I got an error says the installation was not successful. I’m wondering how can I go back to this step to continue installation? I’ve downloaded gigabytes of data and spent quite some time for the device flashing. I don’t want to redo all these again. Besides, all those downloaded files occupied the disk space (thus I don’t have enough space to install now.) If I can only redo everything again, can I simply delete the installation folder to free the space? Thank anyone for your kindly reply.
