I am not yet decided to choose what brand of 10/100BASE-Tx ethernet chip for my small board running FreeRTOS. Any low-cost chip with good document should do the job, but I am thinking I’d better choose a brand that already have some reference implement of a driver that already ported to FreeRTOS, in that way I can get a very easy start point. Do you have some suggestions? Thanks in advance.

I don’t think we have written any drivers for external Ethernet MACs, only those that are peripherals built into an MCU. I think there is a driver for the Microchip 10BaseT external device in the FreeRTOS Interactive site though (forget the name of the Microchip chip).
