altos: Use explicit boot loader signal in ao_boot_reboot

2014-05-16T05:38:40+00:00

Instead of just "knowing" that ao_boot_loader will be passed zero when the application wants to get back to the boot loader, explicitly define the values so that both sides always agree. Signed-off-by: Keith Packard

altos: Run self loader when application sets boot addr to 0

2013-05-08T04:30:26+00:00

This causes the flash loader startup code to fall into the loader when the application sets the boot address to zero. Signed-off-by: Keith Packard

altos: Validate boot chain start address

2013-05-08T03:16:52+00:00

If the first block of boot memory has been smashed, and the start address is bogus, don't bother trying to jump to the application. This makes the system more resiliant to flash failures, presuming the loader erases the first block, programs the other blocks and then finally comes back to program the first block.

altos: Clean up boot loader support

2013-05-08T03:16:36+00:00

Split out code into separate files. Add support for getting back to boot loader from application. Signed-off-by: Keith Packard
