I think there is no public BSP from us for that board, although we have worked a lot with the atmel chips in the past (but usually on custom hardware). You can basically use any BSP for a start and adapt it to your hardware needs. Atmel plays nicely with the mainline kernel, so please start with 3.4.x and check how far you come. > Further more to boot this image on the hardware, do I really have to > use at91bootstrap to load barebox and then barebox to load the kernel? Currently yes. > And to run this image in QEMU will this boot loader not influence > the system? It depends on what you want to achieve by running in QEMU. As a rule of thumb, qemu is often a good thing when it comes to system issues, but if you care about hardware, you should run on hardware. > And the last one (sorry that I puncture you with my questions) At the > moment I can not understand what will happen if I would change for > example the memory. How can I tell that to the controller/ kernel? This is modelled in the open firmware devicetree. Your bootloader has to know the information and put it into the right location. rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | -- ptxdist mailing list ptxdist@pengutronix.de
