If anyone wants to see how it works in practice, then running the attached script will download my new buildroot, and build a complete set of functions to get a board running with Linux.
It will build at91-bootstrap-2.3 with my private additions u-boot-1.2.0 with my private additions linux-2.6.20.4 maxim + experimental patches rootfs (jffs2) rootfs (ext2)
for the following configurations: at91rm9200df* at91rm9200ek running from dataflashcard at91sam9260dfc at91sam9260ek running from dataflashcard at91sam9261ek* at91sam9261 running from internal dataflash at91sam9263ek at91sam9263ek running from dataflashcard
Only the two boards marked '*' have been run on actual H/W yet, the other two boards will be tested when I get my boards back.
Don't try to get support for these things from Atmel since they do not know anything about the internals.
The stuff is also available at: www.at91.com in the AT91 Buildroot project. --------------------------------------------------------------
