This FCB was generated with the attached tool (fcbgen.c) - note that the bad block handling is disabled. Then you can "merge" your barebox image with the FCB with something like: cat fcb.bin barebox-image > barebox-fcb.bin This works at least on our custom i.MX53 hardware. ~Matthias Von: barebox-bounces@lists.infradead.org [mailto:barebox-bounces@lists.infradead.org] Im Auftrag von guenter.gebhardt@rafi.de Gesendet: Montag, 26.

May you please send me a binary produced with this tool? >I want to inspect the flash header. fcb.bin contains a FCB and was generated by this tool. It should instantly work with your i.mx53 barebox. Note that the FCB image must reside within the first blocks of the NAND. The internal ROM loader will always read 4k blocks from NAND - independent of the actual NAND page size. The attached FCB must be located at the start of the NAND. The barebox image must be located at page 2. Assuming a 2k page NAND you should have this: page 0-1: 4k FCB, page 2-n: barebox. ~Matthias > >-- Gebhardt > > > >Von: Matthias Fend <Matthias.Fend@wolfvision.net> >An: "guenter.gebhardt@rafi.de" <guenter.gebhardt@rafi.de>, "barebox@lists.infradead.org" <barebox@lists.infradead.org> >Datum: 26.03.2012 11:09 >Betreff: AW: imx53 internal boot from NAND >________________________________________ > > > >Hi, > >For a quick start you can use the provided FCB (fcb.bin). >This FCB was generated with the attached tool (fcbgen.c) - note that the bad block handling is disabled. > >Then you can "merge" your barebox image with the FCB with something like: >cat fcb.bin barebox-image > barebox-fcb.bin > >This works at least on our custom i.MX53 hardware. > >~Matthias > >Von: barebox-bounces@lists.infradead.org [mailto:barebox-bounces@lists.infradead.org] Im Auftrag von guenter.gebhardt@rafi.de >Gesendet: Montag, 26.
