Linux for SC58x
Linux for SC58x 问题：
ADI官方软件：adi-CrossCoreEmbeddedStudio-linux-x86-2.7.0.deb,adi-LinuxAddinForCCES-linux-x86-1.2.0.deb
配置好路径等，后编译u-boot成功。
build-root时出现：
srw@ubuntu:~/source/buildroot$ make
>>> host-m4 1.4.17 Extracting
xzcat /home/srw/source/buildroot/dl/m4-1.4.17.tar.xz | tar --strip-components=1 -C /home/srw/source/buildroot/output/build/host-m4-1.4.17 -xf -
xzcat: /home/srw/source/buildroot/dl/m4-1.4.17.tar.xz: File format not recognized
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
make: *** [/home/srw/source/buildroot/output/build/host-m4-1.4.17/.stamp_extracted] Error 2
如何解决？
