2010-06-21 03:58:19     New Network-Chip Micrel KSZ-8041NL

Hi all,

 

we have forced our previous Network-Chip (a Micrel KSZ-8721BLI) to a Micrel KSZ-8041NL.

 

This chip is currently (sometimes) working with the same driver (Blackfin 527/536/537 on-chip mac support) on our dist 2008R1.

My question is following: Does anyone know if there are problems with this chip or if there are new drivers avalible?

 

 

 

Best regards,

Patrick

we dont track any micrel parts.  the only one we've tested is the one on the early bf51x ezbrds.

 

if you wanted information about micrel parts, i would think you would want to ask micrel ...

Hi,

 

maybe you can move this thread to the u-boot forum...

 

 

 

Is there a possibility to set some of the MMI Pins to a specivic level on bootup?

 

I think there are some problems with our "Boot-Mode" because the PHY uses some Pins (Colision Detect Output, Carrier Sense Output and Receive Data Valid Output) as "Bootstrap" on reset...

 

 

I use u-boot 2009R1-svn1696

 

 

 

Best regards,

Patrick

there is no way to control the reset state of pins.  that's the point of hardware pull ups/downs.

 

as for u-boot setting pins, it grabs the specific pins it needs only when it actually uses the hardware.  if you want to do something else, add it to your own board-specific misc_init_r.
