Portfolio

Required Skills:
Network socket programming under linux, multithreading, linked list operation, search algorithm, database storage

Project functions:
1. Analyze the structure of the arp package, and use the original socket for grouping and sending
2. Use the link list to save the correspondence between the IP address and the MAC address
3. Use quick search algorithm to find the mapping relationship between IP address and MAC address and firewall restrictions
4. Use tftp protocol to send files and update routing software
5. Finally realize that different LAN IP addresses can be pinged

Router under linux

Required Skills:
Embedded linux development, Embedded system development, Linux kernel, Ubuntu, ARM, Nvidia Jetson tx2

Project functions:
Nvidia Jetson Tx2 motherboard system installation
1.Download the L4T Jetson Tx2 Driver Package (28.2.1) to the host on the nvidia official website, and unzip Tegra186_Linux_R28.2.1_aarch64.tbz2.
2. Download the L4T sample Root File System from the nvidia official website to the host, copy the downloaded file to the Linux_for_Tegra/rootfs directory after decompression in the previous step, and decompress Tegra_Linux_Sample-Root-Filesystem_R28.2.1_aarch64.tbz2 (decompress with sudo).
3. Connect the usb micro interface of the TX2 module to the host and enter the recovery mode.
4. Enter the Linux_for_Tegra directory, download and execute for the first time
sudo ./apply_binaries.sh
5. Mount the network file system method (it is recommended to use this method at the beginning, and then burn to emmc after the file system is fixed)
sudo ./flash.sh -N 192.16
