am3517 Linux development

Other Parts Discussed in Thread: AM3517

Hi there,

My customer has plenty of experience with no OS, and now is hoping to develop with embedded Linux. I know this is an extremely general question, but is there any reference they can use to know how to start?   Their question is how to put the XLoader into a real system?  Where do they put it in the Flash?  Also, what type of Flash can the XLoader use?  Sorry about this, I hope it makes sense!

Additionally, they know they need a NAND Flash, but do they also need to bootstrap a NOR, or can they just use the NAND and XLoader.

Thanks in advance,

    As a starting point, let me point you to the Linux Software developers guide: http://processors.wiki.ti.com/index.php/Sitara_Linux_Software_Developer%E2%80%99s_Guide.

    You will be especially interested in items 11 (rebuilding and flashing bootloaders, including Xloader) and 15 (flash tool user's guide) in the table of contents for the above page.

    Specifically, you can boot from either NOR or NAND on AM3517 (among other options).  The Xloader is flashed to address 0 on a NAND device.  A large number of NAND devices are supported.  I'm not as familiar with the flashing steps for NOR flash, however I do know that the Flash tool does not yet support NOR flashing.

    In the page I referred you to, it may be useful to perform searches using the search bar located just above the large red block TI logo.  The Wiki's are filled with useful information, and often the search bar is the best way to locate what you need.
