11.2.2. Specifying Image File to Boot
On the Armadillo-440, in addition to on-board flash memory it is also possible to boot an image file from storage or a
tftp server. For more information, refer to "Kernel and Userland Placement" in the "Armadillo-400 Series Software Manual."
11.2.3. Other Boot Options
There are a large number of options available aside from those introduced here. For more information refer to a book on
the Linux kernel or the documentation included in the Linux kernel source code (
kernel-source/Documentation/
kernel-parameters.txt
).

11.3. Note on Bootloader Versions
When a bootloader image based on hermit-at v2.0.0 source (loader-armadillo4x0-v2.0.0.bin etc) and a kernel image based
on linux-2.6.26-at7 source (linux-a400-1.00.bin.gz etc) are used on Armadillo-440 board revision Rev.C1 or later boards
(S/N 100201-2195 or greater), a problem exists where the kernel may not boot. This problem only occurs with the above
combination.
On Armadillo-440 board revision Rev.C1 or later boards (S/N 100201-2195 and greater), please use a bootloader image
based on hermit-at v2.0.1 or later source (loader-armadillo4x0-v2.0.1.bin or later).

On Armadillo-440 Rev.C1 and later boards, loader-armadillo4x0-v2.0.1.bin or a later version is written to flash memory in the default factory state.
