did this ever work ?

It worked before. The bellow version is an example.

I have fixed it in u-boot.

There are some kernel images that worked because they do not turn on DSA

driver.

 

--- Mike Frysinger                                           2009-04-28 20:46:58

thanks

 

--- Vivi Li                                                  2009-05-12 04:13:17

OK now. Close it.

There is a hardware bug on the ezboard (rev 1.0).

 

The BF518 RxER input is floating; the RxER pin on the PHY is unconnected. The

driver turns this pin into the RxER input, but without a driving source I have

found that it works "most of the time."  A 10k resistor to ground has

made it 100% stable on my boards.  B17 and B19 on P6 on the bottom of the board

make a perfect place to put a 0402 resistor. :-)

 

--- Mike Frysinger                                           2010-02-23 11:23:51

that's a different issue.  the RxER input is left floating on purpose and the

linux kernel shouldnt be requesting it.  see [#5843].
