[U-Boot-Users] ETHERNET TX problem with ADS860 (MPC850), Using SCC ETHERNET device

[FLAMENT David]

Hello, 
I try to use a ADS860 with a MPC850.
I compile u-boot, dowload in flash and reset.
When reset, I see at prompt this :
 
    Board: ADS rev PILOT
    DRAM:  4M 60ns DRAM:  4 MB
    FLASH:  2 MB
    In:    serial
    Out:   serial
    Err:   serial
    Net:   SCC ETHERNET
    PCMCIA:No card present
    Hit any key to stop autoboot:  0
    ## Booting image at fe080000 ...
    Bad Magic Number
 
After I set configuration of IP service :
 
=>setenv ethaddr 00:01:02:2A:3B:4A;setenv serverip 172.17.21.30;setenv ipaddr 172.17.21.33;setenv gatewayip 172.17.0.1;setenv netmask 255.255.0.0;

And I try to ping to my host :
 
=>ping 172.17.21.30
Using SCC ETHERNET device
TX timeout
TX not ready
TX timeout
ping failed; host 172.17.21.30 is not alive
=>
 
Cable is tested, and I'm sure cable plugged into the right port because the led of ETH-0 and LD10 is on and indicate good link integrity on th TP port.
When ping, Ethernet TX indicator blinks (LD6) is not active but Ethernet RX indicator blinks is active when there are activity on networks ! I don't understand this !
 
If you are a idea ! please !
Thank you for your answer !

How did you configure U-Boot?  Only  the  "FADS850SAR"  configuration
supports  a  MPC850  processor, but you write "ADS860" which does not
fit.

May I recommend to use this as a  door  stop  and  get  some  working
hardware instead?

This is most probably a misconfiguration of U-Boot;  the  MPC850  and
MPC860 use different port pins. I guess you mixed those up.

Best regards,
