Learn more about embedded development in Linux

Learn more about embedded development in Linux-general Linux technology-Linux programming and kernel information. The recent learning gains are still relatively large. The main experience is summarized as follows:

1. install linux. The three files downloaded from the internet, the installation disk, and the files mounted on the virtual machine, only remember that there was a problem during the installation, because the setting of the optical drive was not selected for connected on power, in this way, the disk in the optical drive cannot be found after the restart.

2. Considering the special nature of our office network, we use a proxy to access the Internet. Each machine is assigned a fixed ip address, my virtual machine can only access the Internet through my windows. You can use the NAT mode or host only mode, which is similar to the dual Nic proxy mode.

3. Make sure that the linux configuration file is rewritten strictly, and there cannot be more than one space. Otherwise, an error occurs.

4. An error occurred during build when installing minigui for arm. The reason is that this build uses the arm2410 cross-compiling environment, but the path is incomplete as instructed in the experiment, /root /. bash_profile: Add/opt/host/arm4vl/bin/to the PATH and restart the machine.

5. The reason for ping failure in samba server configuration is that windows or linux has a firewall and ip address conflict. If the ip address configured with ifconfig is effective after restart, You need to reconfigure it.
