Hi @reghund1985 ,
If you are using the RT1024, I highly recommend you use the RT1024 SDK which can be downloaded from this link:
https://mcuxpresso.nxp.com/en/builder?hw=MIMXRT1024-EVK
SDK_2_13_0_MIMXRT1024-EVK\boards\evkmimxrt1024\lwip_examples\lwip_dhcp
Don't use the Cortex M3 driver, use the RT1024 driver.
Wish it helps you!
If you still have questions about it, please kindly let me know.
Best Regards,
Kerry
