Gordon Doughman's Bootloader - 4KB to 2KB mod? - varneybob - Jul 10 14:32:00 2003

Anyone know how to easily mod the bootloader by Gordon, so that only the upper 2KB of Flash are used, instead of 4KB? |

Hmm, is it just as easy as chaning BootBlkSize to 2048? --- In , "varneybob" <varneybob@y...> wrote: > Anyone know how to easily mod the bootloader by Gordon, so that only > the upper 2KB of Flash are used, instead of 4KB? |

Try Orging from $F000 to $F800 and re-assemble. I looked and it should fit to 2048 bytes. I looked at Doug assembled S record and it starts from $F000 to F708 not including the vectors. --- In , "varneybob" <varneybob@y...> wrote: > Hmm, is it just as easy as chaning BootBlkSize to 2048? > > --- In , "varneybob" <varneybob@y...> wrote: > > Anyone know how to easily mod the bootloader by Gordon, so that > only > > the upper 2KB of Flash are used, instead of 4KB? |
