Xilinx Petalinux定制rootfs

petalinux-v2018.2 rootfs配置

开发用到的常用工具，使能如下选项，libgcc-xilinx和libgcc-xilinx-dev两个库是为了添加libgcc_s.so.1，来使用pthread_exit()函数这两个软件包找不到其实。

增加软件包

petalinux采用yocto来制作跟文件系统，比如iperf3，在petalinux rootfs的menuconfig中是没有的，需要手动配置，iperf3 recipe位置在，

zc@ubuntu:~/program/petalinux-v2018.2-final/components/yocto/source/aarch64/layers/meta-openembedded/meta-oe/recipes-benchmark/iperf3$ ls -l
total 8
drwxr-xr-x 2 zc zc 4096 Jun  8  2018 iperf3
-rw-r--r-- 1 zc zc 1171 Jun  8  2018 iperf3_3.2.bb

在工程的meta-user里添加该软件包，双引号里记得加个空格，

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2/project-spec/meta-user/recipes-core/images$ cat petalinux-image.bbappend 
#Note: Mention Each package in individual line
#      cascaded representation with line breaks are not valid in this file.
IMAGE_INSTALL_append = " peekpoke"
IMAGE_INSTALL_append = " gpio-demo"
IMAGE_INSTALL_append = " iperf3"

使能该软件包，

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2$ petalinux-config -c rootfs

iperf3选项可以选中，

编译，

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2$ petalinux-build

对于petalinux-image-full中的recipes，有sstate locked，在project-spec/meta-user/conf/petalinuxbsp.conf文件中添加SIGGENE_UNLOCKED_RECIPES += "my-recipe"来unlock。

zc@ubuntu:~/project/petalinux/zynqmp-v2018.2$ cat project-spec/meta-user/conf/petalinuxbsp.conf 
#User Configuration

#OE_TERMINAL = "tmux"

# Add EXTRA_IMAGEDEPENDS default components
EXTRA_IMAGEDEPENDS_append_zynqmp = " virtual/fsbl virtual/pmu-firmware arm-trusted-firmware"
EXTRA_IMAGEDEPENDS_append_zynq = " virtual/fsbl"
EXTRA_IMAGEDEPENDS_append_microblaze = " virtual/fsboot virtual/elfrealloc"


#Remove all qemu contents
IMAGE_CLASSES_remove = "image-types-xilinx-qemu qemuboot-xilinx"
IMAGE_FSTYPES_remove = "wic.qemu-sd"
