I'm inferring here that for MMC boot this checksum is ignored by the BROM? If that is the case then I think it should be explicitly mentioned. As well as the checksum this also changes the header's length field, FWIW. > Signed-off-by: Daniel Kochmański <dkochman...@turtle-solutions.eu> > Cc: Ian Campbell <i...@hellion.org.uk> > Cc: Hans De Goede <hdego...@redhat.com> > --- > > tools/mksunxiboot.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/tools/mksunxiboot.c b/tools/mksunxiboot.c > index 0035f6e..bef0c79 100644 > --- a/tools/mksunxiboot.c > +++ b/tools/mksunxiboot.c > @@ -65,7 +65,7 @@ int gen_check_sum(struct boot_file_head *head_p) > > #define SUN4I_SRAM_SIZE 0x7600 /* 0x7748+ is used by BROM */ > #define SRAM_LOAD_MAX_SIZE (SUN4I_SRAM_SIZE - sizeof(struct boot_file_head)) > -#define BLOCK_SIZE 512 > +#define BLOCK_SIZE 0x2000 > > struct boot_img { > struct boot_file_head header; _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
