Primary Boot Loader
There are two boot loaders present on the NOR flash memory chip. Secondary is the main one, that is
executed by default. This is the one that can be upgraded. In case something goes wrong in the upgrade
process, or you have set some incorrect settings that render it unusable, you can load the Primary boot loader
by holding the Software Reset 1 button (
S1
), connecting the power, and then releasing the button/jumper. The
Primary boot loader has the default settings, which can not be changed. It is also not possible to upgrade it.
