Is loopback supported in RMII mode

asmaa — Thu, 20 Jun 2019 05:50:56 GMT

Hi Everyone,

I am using MCIMX6G3 in non linux mode. I want to test ethernet driver in RMII mode. I am using ENET2.

Do MCIMX6G3 supports loopback with PHY in RMII mode?

Regards,

Asma

Hi Asma

seems it is not supported as sect.22.5.9 Receive Control Register (ENETx_RCR)

i.MX6UL Reference Manual describes it: LOOP, in RMII_MODE must be written to 0.
0 Loopback disabled.

Hi igorpadykov‌, naoumgitnik‌

https://community.nxp.com/thread/318899.

Can I get the header files for the source code that has been shared on the above link.

#include "enet.h"
#include "eth.h"
#include "macnet.h"/*register definition*/
#include "macnet_hal.h"/*SoC implementation*/

I am working on implementing bare metal program for ethernet MAC RMII mode on MCIMX6G3. looks like the code that you have shared on the above link is relevant to my dev.

Or can I get the freescale driver for MAC on IMX6. I found imx_enet.c on searching google, but I am not sure if its correct?

Asma
