Hi,
I have waste so much time in search but without success and I hope you can help me by answering my question about ethernet access from Cortex-M4.
Is it possible to use the ethernet interface for example with FreeRTOS on the Cortex-M4?
Is this possible in principial?
For many other processors including the i.MX 7ULP there exists muiltiple useful files for example fsl_clock.c/h, fsl_common.c/h, and <processor>_features.h files. Do they exist also for the i.MX 7Dual processor? If yes, where can i get these files?
The exact processor: MCIMX7D5EVM10SC
Thanks in advance for your reply.

sorry I am not aware of such files for FreeRTOS.
I think you should develop them yourself using for example uboot sources.
Best regards

yes possible. One can look at 2.1.3 Cortex-M4 Memory Map (AIPS-3, ENET)
i.MX 7Dual Applications Processor Reference Manua
Access permissions may be configured with RDC described in sect.3.2
Resource Domain Controller (RDC)
Uboot enet example can be reused for porting to FreeRTOS
mx7dsabresd.c\mx7dsabresd\freescale\board - uboot-imx - i.MX U-Boot
fec_mxc.c\net\drivers - uboot-imx - i.MX U-Boot
