My firmware is made of a bootloader and an application.
Only one is running at a time but both start by initializing the lwip
launching a DHCP discovery in order to get an IP address.
In the case of
my application is running an IP address is assigned to my application.
is possible to jump from my application to my bootloader. The
re-inits the lwip stack and calls DHCP for an IP address: when I sniff
network, I see that the bootloader sends a DHCP discovery. My problem
is that I
want that my bootloader keeps the same IP address that was assigned to
application. My understanding of the DHCP protocol is that a DHCP
propose an IP address to the DHCP server; in this case, the DHCP client
send a DHCP request instead of a DHCP discovery. Does lwip support this
feature? How? How should I do to keep the same IP address for my
