Is it possible to build software packages directly on SOM60 / IG60?
While for the Linux enthusiat it is surely not impossible to build and image for the SOM60 or IG60 that supports on device build capabilities with the given tools, it is neither intended by Laird, nor is it supported.
Reason for this are the limited resources (memory and processing power) an embedded module such as SOM60 and an embedded gateway like the IG60 can offer for on device building capabilities.
The preferred method would be to include any packages desired on the SOM60 or IG60 into the Buildroot SDK.
