5.4 Selecting the Boot Flashes
There are two ways to select the boot flashes and thus determine which flash the ATCA-F120 is
to boot from during the next restart:
Via IPMI
Via an U-Boot command
One way to switch between the two boot flashes and thus determine which boot flash the
ATCA-F120 is to boot from, is via IPMI using the System Boot Options feature. Refer to the ATCA-
F120: Control via IPMI Programmer's Reference for details.
Alternatively, you can use the U-Boot command bootsel. Its usage is: bootsel
0|1|switch, where 0 selects boot flash 0, 1 selects boot flash 1 and switch selects the
currently stand-by boot flash.
Generally, there is a fixed link between the U-Boot firmware and the kernel image in the
respective boot flash. This means that when the U-Boot in a particular flash is executed, it will
subsequently boot the kernel image in the same flash.
If necessary, however, you can select the kernel to boot manually via the following commands:
setenv kerneladdr fe020000 (for the kernel in the currently active boot flash) and
setenv kerneladdr fc020000 (for the kernel in the currently stand-by boot flash). Use
these commands with care.
