i.MX 7Dual ethernet connection

[andreas_vorderl]

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.

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 

Best regards

Do you know if there are such files for the i.MX 7Dual processor?

Best regards,

sorry I am not aware of such files for FreeRTOS.

I think you should develop them yourself using for example uboot sources.
