Automatic bootloader
PostPosted: Fri Jun 01, 2007 6:17 am     Reply with quote
Looking for a bootloader, I found that available as example.
I' looking for a bootloader/downloader that don't require to press a switch at reset/power-up time, but the bootloader checks itself at startup, for a limited time amount, if the downloader is active: if yes, the download is performed, otherwise (non signals from downloader in the timeout interval), the currently installed program is executed.
Has the provided downloader/bootloader such a behavior?
If not, has anyone something to suggest about ?

The bootloader remains active for 0.2 seconds after reset, to give you
the option of uploading new code
