S32G274A EVB ethernet connection

[bbbjj]

i want  to connect my host pc with s32g274a evb 

but  after booting, there is error log like this 

"

[ 3835.581829] 002: s32cc-dwmac 4033c000.ethernet eth0: no phy at addr -1
[ 3835.581849] 002: s32cc-dwmac 4033c000.ethernet eth0: stmmac_open: Cannot attach to PHY (error: -19)

"

So, i cannot do anything about the eth0 

how can i solve this?

Hi @bbbjj ,

I hope you are doing good.

This issue seems that PHY Address is used wrong or PHY is not powered up correctly.

Can you please share the DTS file for checking configurations? Which BSP version are you using?

Have you made additional changes in BSP for enabling ethernet?

Thanks,

Hi @MayanksPatel :

Thanks for your relay, I'm having the same issue.

I am using those commands to build Ubuntu-ros for Goldbox2.
Besides, I compiled according to the instructions below and did not modify any of the source files.

source nxp-setup-alb.sh -m s32g274aevbubuntu

bitbake fsl-image-ubuntu-ros

After a successful build, I am not able to provide internet connection to my Goldbox. 

During Startup I see the following error:

[ 4442.216923] s32cc-dwmac 4033c000.ethernet eth0: no phy found
[ 4442.216931] s32cc-dwmac 4033c000.ethernet eth0: stmmac_open: Cannot attach to PHY (error: -19)

Any suggestions and information are welcome, thanks in advance.

Dennis.
