Re: [lwip-users] LwIP bootloader stack deinitialisation

[Philipp Tölke]

I am using it like this; the bootloader uses lwip and then jumps into the
firmware-code. The firmware is a completely different program (even with
different lwip-config) and just initializes everything like it had just
booted from a power-on.

Be careful about your hardware though! We use microcontrollers by TI and
they do not mind being initialized twice but I would imagine that some
hardware would need to be carefully reset in order to work.
