Custom Bootloader

I have an idea for a sansa bootloader that would load the original firmware by default, and rockbox if you hold |

saratoga:
Its pretty easy to do this on most ports.  I haven't tried the sansa, but looking at the bootloader, theres a simple block like so:

if()
  printf("Loading original firmware...");
...
else
 printf("Loading Rockbox...");

Looks like all you need to do is negate the condition inside the if and you'd have it.

digerati1338:
I thought it would be really simple like that.  Ill try it later tonight when I have some time.  Thanks.

Found the file and changed it, but I can't seem to find any helpful information for building a bootloader and I'm a little bit confused.  

From what I've read, it isn't recommended because bugs in the code could brick your player.  I'm not too worried about this since I can just use recovery mode if it bricks.

To compile it do I just make a build dir and then run ../tools/configure, select my target, hit B to build bootloader, and then run make?  Do I need to run make zip or make install?

007quick:
It is to my experience that you are correct. Just run configure select B then run make. You should get the appropriate file in your build dir.
