Installation of zynq platform cross compiler

One 、 Create a working directory

Create a new working directory zynq, And enter the directory . newly build packs Catalog , The purpose is to store the source installation package , Copy relevant files to this directory .

mkdir zynq
cd zynq
mkdir packs

Two 、 Unzip the file

decompression Sourcery_CodeBench_Lite_for_Xilinx_GNU_Linux.tar.gz File to packs Under the parent directory of , I.e. working directory $zynq$ Directory .

tar -zxvf Sourcery_CodeBench_Lite_for_Xilinx_GNU_Linux.tar.gz -C ../

For the convenience of subsequent operation , We rename this folder ：

mv Sourcery_CodeBench_Lite_for_Xilinx_GNU_Linux xilinx-tools

3、 ... and 、 Write an activation script and activate

establish env_z7.sh And enter the following into it , It's better to put it in zynq Under the table of contents

#!/bin/sh
export PATH=/home/mangata/zynq/xilinx-tools/bin:${
    PATH}
ARCH=arm
CROSS_COMPILE=arm-linux

Activate script ：

source env_z7.sh

Four 、 Test compiler version

Generally speaking, it will report an error ：

mangata@mangata:~/zynq$ arm-linux-gcc -v
-bash: /home/mangata/zynq/xilinx-tools/bin/arm-linux-gcc:  There is no file or directory 

Said the command was not found , This is because the compiler is $32$ position , And our system is $64$ Bit , Need to install $32b$ Bit Library . Let's continue to enter the installation command ：

sudo apt install libc6-i386 lib32z1

If the installation here reports an error ：

 error :1 http://cn.archive.ubuntu.com/ubuntu focal-updates/main amd64 lib32z1 amd64 1:1.2.11.dfsg-2ubuntu1.2
  404  Not Found [IP: 91.189.91.38 80]
E:  Unable to download  http://cn.archive.ubuntu.com/ubuntu/pool/main/z/zlib/lib32z1_1.2.11.dfsg-2ubuntu1.2_amd64.deb  404  Not Found [IP: 91.189.91.38 80]
E:  Several packages cannot be downloaded , Do not run  apt-get update  Or add  --fix-missing  Try again ？

Then we just need to enter ：

sudo apt-get update

Just install it again

Then check the version number again ：

So far about zynq The cross compiler installation of the platform is completed
