I was wondering if anyone has ever attempted to build a 32-bit kernel to run on an RZ/G2 or RCAR3 SoC. I have a variant with than 2GB of RAM, and I want to run some experiments to measure RAM utilization and performance to see if it's worth trying to run in 32-bit mode to save a little RAM. It looks like U-Boot supports AARCH32, but most of the stuff I can find when searching has people building applications in 32-bit space running on a 64-bit kernel, but I am hoping to try everything in 32-bit mode. I have build the multi_v7 kernel with an ARMv7 compiler, but attempts to boot that kernel cause a crash. I am guessing I need to enable some additional flag somewhere, or somehow tell U-Boot it's a 32-bit kernel. thanks in advance. adam
