I tested with the buildman-fetched gcc, -v gives 'gcc version 4.9.0 (GCC)'. I've deleted the toolchain and re-fetched it again through buildman in case there was an issue with the install, and am getting the same result. I've also tested with the latest ARM gcc package available with Ubuntu, that is, 'gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu1)', again with the same result. > I see for the axm board: > > With eldk-5.4 > pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot > text data bss dec hex filename > 212583 23792 23552 259927 3f757 u-boot > pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl > text data bss dec hex filename > 14568 1212 1140 16920 4218 spl/u-boot-spl > pollux:u-boot-smartweb hs [master] $ Confirmed right now that with eldk 5.4's gcc 4.7.2 axm builds fine. > With eldk-5.5 > pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot > text data bss dec hex filename > 210690 23672 23556 257918 3ef7e u-boot > pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl > text data bss dec hex filename > 14472 1212 1140 16824 41b8 spl/u-boot-spl > pollux:u-boot-smartweb hs [master] $ Confirmed right now that with eldk 5.5's (or 5.5.3's) gcc 4.8.1 axm builds fine.

I think the first step in debugging (as I've done this before) is bump the limit up so you can link and then examine the map file to look for suspicious things to try and discard (or strings to play around with so they can be never included, along with the function that was already discarded). -- Tom -------------- next part -------------- A non-text attachment was scrubbed...
