Net: No ETH PHY detected!!!

Added by Jordi Perez Serra over 6 years ago

Hello,

I have a mitydspl138 board. I accidentally overwrote some of the u-boot memory. I used the serial programmer to re-flash u-boot
https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Reprogramming_a_Dead_Board

But now I get this error message on bootup.

Enet config : 0
Net: No ETH PHY detected!!!

I have checked and the version of u-boot and UBL are the same as before the incident
UBL Version: 1.65:2.28.1 BuiltJul 11 2011 12:49:53
U-Boot 2009.11 (Mar 31 2011 - 19:39:18)

I have tried using the older versions provided by CritialLink and compiling my own new ones but with no difference.

Additionally:
Running mii device responds with nothing.
U-Boot > mii device
MII devices:
U-Boot >

'mii info' and 'mii info 3' spams 'NULL device name!' at me.

I also noticed that the config item 'Ethernet Config' is set to 0 when it should be set to 1 or 2. I tried following the instructions here https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Network_configuration
But I cannot change the value from 0. I'm not sure if this setting is the cause or just a victim of the problem.

Thank you for any help.

I used the serial flashing program to erase the memory before flashing u-boot again and this time phy eth is detected and networking works normally.

I'm sorry for the trouble.
