Problem trying to include ethernet platform on LwIP/Free_RTOS build on CYW943907 hw platform

[Gare_4782551]

I wrote an ethernetif.c driver that uses functions in platform_ethernet.c, but not sure how to get the platform code to build in this configuration.  I get errors (see below) due to the platform code not being built.   For NetX_Duo/ThreadX, the platform code does get built.   Not sure what the 'correct' way to get this included in the build LwIP/FreeRTOS is (i.e. do I need to modify a makefile or is there a define that is needed for this config).

Found out it's due to this (in peripherals.mk):

ifeq (,$(APP_WWD_ONLY)$(NS_WWD_ONLY)$(RTOS_WWD_ONLY)$(PLATFORM_NO_GMAC))
$(NAME)_COMPONENTS += MCU/BCM4390x/peripherals/ethernet
else
GLOBAL_DEFINES += PLATFORM_NO_GMAC=1
endif

So building WWD only with Ethernet is not supported, is there a way around this?

Hi,

Is the build issue gone or do you still face some build issues? What's the make target? From the description, it seems you're using the ping example of the wwd folder, right?

Thanks
