[Icc-avr] Bootloader problem

[Sylvain Bissonnette]

Hi Rodney,

    Hmmm, it's 256 word, 256k for a bootloader is a little big,  If I modify the init.s what I must do to say to the
compiler to use my init.s and not the original one?

Thanks
Sylvain

  Hi Sylvain -

   

  I'm assuming you meant 256 bytes, not 256k? (words? Bytes?)

   

  Either way you can save space in the start up file be removing the code that initializes the memory of SRAM (assuming you are not using SRAM in the same manner as "normal" application code).  Take a look in the init.s startup file - that is where the initialization code is located.  It is in Assembly.

   

  Cheers!

  Hi,

   

      I'm currently working on my MegaLoad bootloader and I want to fit this one in 256k size.  when compiling

  I get not large enough... I need only couple of byte more.  I don't use any interrupt, is there some way to

  get a bit more maybe in the startup file? but I never had work with the startup and I don't really now how

  to do this.  Any help will be welcome.

   

  Thanks
