Allow to generate 'u-boot.nand', Freescale i.MX28 BootStream format (.sb) with a header for booting from NAND flash. There are two possibilities when preparing an image writable to NAND flash: 1) The NAND was not written at all yet or the BCB (Boot Control Blocks) is broken. In this case, the NAND image 'u-boot.nand' needs to written. 2) The NAND flash was already written with a good BCB. This applies after 'u-boot.nand' was correctly written. There is no need to write the BCB again. In this case, the bootloader can be upgraded by writing 'u-boot.sb'. To satisfy both cases 'u-boot.nand' as well as the make target 'u-boot.sb' are copied to the binaries directory. mxsboot for NAND images needs all three parameters typed in as integer values (hex values do not work). The default values choosen are typical sizes for a NAND flash.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
