Advanced boot options availability

The ReliaGATE 10-12 bootloader provides a number of advanced boot options, that allow a developer to
run different build artifacts.
The following advanced boot options are currently available:
Boot option
fitboot
fitImagetftpboot
zImageboot
zImagetftpboot
If you are using a tftp boot option (fitImagetftpboot or zImagetftpboot), note that:
The system will use the tftp server specified by serverip and it assumes that a dhcp
l
address can be obtained through interface eth0. Always ensure that this ties in with your
network architecture before attempting to boot the tftp options
All runtime artifacts are loaded into RAM before execution, no execution from flash is
l
currently supported.

which boots the production
kernel fitimage.
This option is a fast and easy
way to test development
fitImages.
This option is a way to boot a
production zImage and device,
should the default verified boot
system not be required.
This option is a fast and easy
way to develop kernel images
and device trees.
