No problem. > When configuring without --with-arch=armv7-a and using -mthumb flag > thumb-1 is been tested. I don't understand "using -mthumb" . Are you manually adding -mthumb to your boot C flags ? If you are trying to bootstrap in Thumb state use the configuration knob --with-mode=thumb and the value you pass to --with-arch or -with-cpu will ensure that this gets the right level of the Thumb ISA. Thus the compiler will bootstrap using the Thumb2 ISA, if you use --with-arch=armv7-a . If you use anything less than or equal to --with-arch=armv6 or a cpu that implements v6 or lower of the architecture you'll end up bootstrapping with Thumb1. Are you saying that Thumb1 bootstraps are broken with SMS / do-loop and debug info ? cheers Ramana _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
