8.3 Loading files onto the Core Module
If you have access to Ethernet via your Bluetechnix board and a TFTP server is installed on
your workstation, you can transfer any file from the TFTP server to the Core Module by

at the U‐Boot prompt. After the transfer is complete, the file size is printed to the terminal.
The default load address is 0x1000000 in RAM memory. It can be specified optionally before
