Sounds like a plan. I've done this, and also moved the files to board/compal/paz00 as suggested elsewhere. >>> +#define V_PROMPT "Tegra2 (Paz00) # " >>> +#define CONFIG_TEGRA2_BOARD_STRING "NVIDIA Paz00" >>> + >>> +/* Board-specific serial config */ >>> +#define CONFIG_SERIAL_MULTI >>> +#define CONFIG_TEGRA2_ENABLE_UARTA >>> +#define CONFIG_SYS_NS16550_COM1 NV_PA_APB_UARTA_BASE >>> + >>> +#define CONFIG_MACH_TYPE MACH_TYPE_PAZ00 >>> +/* >>> + * The following should be 512MB, but I don't know how to set that >>> value >>> + * It doesn't matter, since this isn't really used any more >>> + */ >>> +#define CONFIG_SYS_BOARD_ODMDATA 0x200d8011 /* lp1, 1GB */ > > I don't know what is the effect of this paramter, but paz00 has 512 MB.

OK, I've switched to that value (where did you extract it from, BTW), and after fixing a bug in arch/arm/cpu/armv7/tegra2/board.c:query_sdram_size() (default==512M, not 1G), it all works. -- nvpublic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
