URBoot is too fast, making manual reset more difficult... #28

Perhaps the default WDT timeout should be 1s rather than 500ms

stefanrueger commented 7 months ago

Although the C source has a default of 500 ms, the accompanying Makefile overrides, by default, the timeout to be 1 s. The precompiled bootloaders from the urboot.hex repository give a choice of 1 s or 2 s timeout when branching to the desired bootloader.

It is unlikely that a user creates a bootloader by compiling the C source from the command line (though they can): it is recommended to use the Makefile, which invokes a gcc-wrapper to carry out proper positioning of the bootloader sections.
