petalinux离线编译Linux镜像

Posted on 2019-10-31 In Embeded

petalinux编译linux镜像默认会去 petalinux.xilinx.com下载编译过程中需要的资源包, 如果网络不好或者petalinux所在的那台服务器被限制上网的话, 就编译不了. 但其实xilinx官方提供了离线资源包下载, 只需要预先把集合了所有资源的压缩包下载解压到本地, 通过设置petalinux mirror路径选项就能使用离线资源编译Linux镜像(已测试可行的版本petalinux 2017.4/2018.2/2018.3/2019.1) , 下面以petalinux 2018.2为例实际操作一下.

xilinx自带的说明文档sstate_rel_2018.2_README


By default petalinux uses sstate-cache and download mirrors from petalinux.xilinx.com
This README is for the users who uses tool completely offline.

Setting sstate cache

1) Extract the downloaded tar contents of sstate-cache at any location
2) run petalinux-config
         -> Yocto Settings
             ->Local sstate feeds settings
                  ->local sstate feeds url
                          (press Enter)
3) Provide the path of sstate-cache from above
           Ex: /<path>/aarch64  for ZynqMP projects
               /<path>/arm      for Zynq projects
               /<path>/mb-full  for MB AXI full projects

4) Save the configurations to use the sstate-cache

Setting download mirror

1) Extract the downloaded tar contents of sstate-cache at any location
2) run petalinux-config
        -> Yocto Settings
                -> Add pre-mirror url
						          ->  (press Enter)
							            Clear default value

3) Provide the path of sstate-cache from above
        file://<path>/downloads for all projects

4) Save the configurations to use the download mirrors

5) Verify the changes in build/conf/plnxtool.conf
6) petalinux-build
