I'm new to embedded and am reading 'Embedded Linux Primer' at the moment.I tried to build an xscale arm kernel: make ARCH=arm CROSS_COMPILE=xscale_be- ixp4xx_defconfig## configuration written to .configfollowed by the make:~/linux-stable$ make ARCH=arm CROSS_COMPILE=xscale_be- zImagemake: xscale_be-gcc: Command not found  CHK     include/config/kernel.release  CHK     include/generated/uapi/linux/version.h  CHK     include/generated/utsrelease.hmake[1]: `include/generated/mach-types.h' is up to date.  CC      kernel/bounds.s/bin/sh: 1: xscale_be-gcc: not foundmake[1]: *** [kernel/bounds.s] Error 127make: *** [prepare0] Error 2I had downloaded and extracted gcc-arm-none-eabi-4_9-2014q4 fromhttps://launchpad.net/gcc-arm-embeddedand set the pathPATH=/opt/gcc-arm-none-eabi-4_9-2014q4/bin/Do I need another compiler for the xscale architecture?Any ideas where I can find xscale_be-gcc?

I'm reading the same book and get stuck in the same part, so... after some research i finally compiled the kernel for ixp4xx targetDownload the ARM toolchain from:Devloper arm Compiler v6then...$ mkdir -p ~/opt $ cd ~/opt $ tar xjf ~/Downloads/gcc-arm-none-eabi-6-2017-q2-update-linux.tar.bz2 $ chmod -R -w ~/opt/gcc-arm-none-eabi-6-2017-q2-updatelook if the installation is correct ~/opt$ gcc-arm-none-eabi-6-2017-q2-update/bin/arm-none-eabi-gcc --version The output will be something like this: arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors 6-2017-q2-update) 6.3.1 20170620 (release) [ARM/embedded-6-branch revision 249437]  Copyright (C) 2016 Free Software Foundation, Inc... Now you can prepare your Kernel source tree make ARCH=arm CROSS_COMPILE=~/opt/gcc-arm-none-eabi-6-2017-q2-update/bin/arm-none-eabi- ixp4xx_defconfig And finally compile... make ARCH=arm CROSS_COMPILE=~/opt/gcc-arm-none-eabi-6-2017-q2-update/bin/arm-none-eabi- zImageMaybe it is not the best compiler for the target or need a kernel patch but... in order to follow each step in the book i think is enough.BR,
