In that case, I'll stick with the BSP management improvements once v4
of this patch set goes in (probably) and skip the generic build.
Is a generic build something that would be worth pursuing for lwIP?
It would come with the core stacks, but no drivers whatsoever.
I'm very exited about that stuff, and here is a project I'm entertaining:
Using LWIP on the Cortex-M4 side of a stm32h747:
- Without the ethernet driver.
- With an emulated, ethernet USB driver (device-side USB, I will
write the driver if it does not exist yet).
- Talking to a cellular modem with PPP over USB (host-side USB, I
will write the driver if it does not exist yet).
Can I, today, configure a basic/generic LWIP stack that would allow to
develop such a setup?
Currently all rtems-lwip build configurations are very BSP-specific and
include drivers with no options to leave the drivers out of the build.
Additionally, there is no option for a generic build for BSPs that
aren't specifically supported.
It's possible that we could build a generic stack for BSPs that aren't
otherwise supported with drivers, but I'm waiting on some things to
settle out (specifically STM32F4 support) before I move forward with any
more changes that could disrupt that.
I'm also focused elsewhere for the moment, so waiting on things to
settle out is fine.
