Hi, Simon: Sandbox concept is a very good idea to test uboot's non-platform part code.
I have a question about compiling uboot sandbox branch: 1. It seems sandbox branch could be compiled by gcc compiler on a x86 platform. Not need to set cross compiler tool chains. And after finished compiling, it could be run on a x86 environment. So, my question is: Arm cross compiler tool chains could produce different obj file for a same .C file. The obj file for a same .C file by arm cross compiler tool chain is not different with the obj file produced by a x86 gcc tool. (On my x86 platform, defaut gcc is a x86 version)
So, for more precise test for non-platform code: User should compile sandbox branch with an arm cross compiler tool chain. And should run it on an arm linux environment?
Best wishes,
