Thank you for answering my question .I mean whether it is workable that I download the all needed package at home and than bring them to a no internet environment to build the edison image.
Otherwise I saw the below passage in Doc Source Level Debug using OpenOCD/GDB/Eclipse on Intel® Quark™ SoC X1000 ,and I don't no whether it is workable for edison ,if so how to implement?
The step above can take as long as several hours, because all packages need to
be fetched from the internet and then built. If you have already downloaded all
the files previously (they will be stored in yocto_build/downloads), you can
execute a build without doing sanity checks on the network to save time. Disable
sanity checks by adding this line in the yocto_build/conf/local.conf file:
CONNECTIVITY_CHECK_URIS = ""
Especially, should I be deep into the sanity checks process to do this work?
Appreciate so much!
