6.5.4.2 Contacting the Server
In addition, to be able to transfer files from a tftp server to a module, the module’s IP address (environment variable
“ipaddr”) and the IP address of the server must be set (environment variable “serverip”). Alternatively, it is possible to use
the “dhcp” or “bootp” commands.
They can be set using the “setenv” command. Please note that these settings are lost after a reset. To retain the environ-

To transfer a file from a tftp server to memory, the “tftpboot” command is used, for example:

which loads the file “kernel.bin” from the SD card to memory address 0x100000.
6.5.6 Using USB Devices
