Hit any key to stop autoboot: 0
The start message contains information about
●
Version of the bootloader
●
Configuration of the CPU (e.g. clock frequency, memory extension)
●
Hardware revision of the CPU module
After the transmission of the start message (see above) the operating system is loaded.
The loading procedure can be stopped by pushing the SPACE key.
In this case you get to the bootloader prompt („=>“).
Now the bootloader can be configured by a variety of commands.
6.1.2 Firmware Configuration
The configuration of the bootloader is stored in the so called environment variables. Enter the
command
printenv
for a listing of all environment variables
.
The following output contains the complete environment of the EPPC-T10 unit in the state of
