In any case, thanks for digging into MAKEALL! Any bug you see sure will go in 2013.04. If you need any help for cross-checking issue on another setup than yours, please ping me, either in To: or through IRC. BTW, recently I have seen MAKEALL -a arm fail sporadically on some boards during parallel builds; more specifically, with BUILD_NBUILDS=8 and BUILD_NCPUS=1. Note that the actual machine has a 4-core, 8-thread CPU, so maybe that was because the number of parallel builds was just equal to the number of (pseudo) CPUs available; I am now using six parallel builds and haven't seen the issue again so far. (also, I prepend the command with LANG=C to avoid making the error messages any more French than they already are when I copy-paste them to the list. Not sure how that could have any influence on the build errors, of course.) Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
