3.3 Test K2H FTP Server Example

An out file called NIMU_FtpExample_EVMK2H_armExampleProject.out should be built. The example runs as the FTP server with a default IP address 192.168.1.4 on the K2H EVM. The PC acts as the FTP client with an IP address 192.168.1.11 as an example. The major test steps include:

  • Set the K2H EVM in no-boot mode and use the standard GEL file for initialization
  • Use CCS/JTAG to connect to the first A15 (arm_A15_0) core, load the program and run
  • From the PC side, FTP to EVM with User: user and Password: password
  • From the PC side, use get command to read a file from EVM into PC and put command to send a file from PC to EVM, corresponding to EVM transmission and reception, respectively

A sample test screenshot shown in Figure 3-5, showing the PC test commands and FTP throughput reported. This proves the functionality of the K2H FTP server example. Note that the server does not really host a file system on the K2H EVM, get/put commands are simply memory operations.
