Okay, I know I'm not totally stupid about such things, but if you've got any idea how to successfully load the output of buildroot on to an AT91SAM9261-EK (or, for that matter, an AT91SAM9RL-EK or AT91SAM9XE-EK) Atmel ARM dev kit, using SAM-BA, could you give me a hand? I thought I understood the process, I think I know where everything should be going, but at best I'm getting:
RomBOOT
>Start AT91Bootstrap...
>AT45DB62D detected
>Invalid Boot Area...
>Start application at [0x23f00000]

Awesome! Up and running, definitely going to need to document this, especially after I figure out why my compiles of the boot loaders aren't working, and once I understand better what the details of the various storage devices are.
Aaand, a few issues that I'm getting spew from the kernel on boot about, if I solve all of those issues I may be able to get boot to circa 10 seconds, which might be fast enough that I can convince those involved that Linux is a reasonable platform for this device (5 seconds is the current "gotta be at least" number).

[edit history]
And this page describes the bus width fix for the Linux kernel on the AT91SAM9261-EK and AT91SAM9293-EK devices.

Okay, getting further. Turns out everyone uses different flash locations for their images, I'm trying to figure out what buildroot uses so that I can pass that to the programmer script. Sigh.
We will not edit your comments. However, we may delete your
comments, or cause them to be hidden behind another link, if we feel
they detract from the conversation. Commercial plugs are fine,
if they are relevant to the conversation, and if you don't
try to pretend to be a consumer. Annoying endorsements will be deleted
if you're lucky, if you're not a whole bunch of people smarter and
more articulate than you will ridicule you, and we will leave
such ridicule in place.
