I ended up = booting the BSP linux kernel and root file system off of SD, and it was = able to access the NAND device while simultaneously using the SD device = (as the root filesystem source) so there doesn't seem to be any inherent = hardware limitation preventing bareboot from accessing it. Just for fun, I tried to use the kobs-ng freescale tool from within the = linux environment to burn the bareboot bootstream to NAND. However, = after trying to boot, I receive the error code 0x80501003 from the ROM = loader, which evidently indicates "The file signature or file version is = incorrect". The exact same bootstream on an SD card boots fine, so I = don't think there's anything wrong with it. I also tried to burn the BSP = linux kernel bootstream, with the same result. (Side question, what's = the difference in the bootstream files that contain "ivt" in the = filename? I used the non-ivt versions on SD, I tried both on NAND with = neither working). The board came from the factory with a working kernel on NAND, so I know = it can work. Given I'm using the freescale supplied linux environment = and their nand bootstream burning tool you'd think it would be fairly = straightforward=85 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
