Best Option for Wired Ethernet

I am considering using the MSP432 Controller with Ti-RTOS for an embedded application that requires hard wired ethernet capability and I am wondering what my best option is in implementing this system. Key requirement is GPIO's with I2C for monitoring and hardwared ethernet for reporting events.

I don't need the horsepower of the C series CPU with ethernet and would prefer the MSP432 for cost sensitivity and ease of use. Power consumption isn't critical as the system runs of AC and there is a back up UPS. If wireless was an options, i would opt for the SimpleLink C3X cpu.

If I use the TI-RTOS, it looks like, we will  have to write custom device drivers to support what ever ethernet MAC+PHY chip we use. How easy is that and how difficult is that to integrate with the TCP/IP stack that is available.

There is also the Wiznet series of chips but not sure how to integrate those with TI-RTOS.


Any advice would be appreciated.

Thanks!

    Nobody can tell how easy it will be for _you_ :) Why don't you get device driver source code for microcontroller having built-in MAC/PHY and see for yourself - how complex is code, how much code lines and so on?
