[ECOS] Redboot Ethernet with AC101L PHY

[Andrew McKay]

Hello Everyone,

I working on getting RedBoot up and running on a EP9301/EP9302.  I have 
the EDB9302 development kit from Cirrus Logic, and have successfully 
loaded RedBoot on it.  However we have designed our own board and seem 
to be having difficulties with the ethernet in RedBoot.  The only 
difference between our board and the development kit is that we used a 
AC101L external Phy from Altima (Broadcom), and the development kit uses 
a CS8952 external Phy from Cirrius Logic.  I  have been through the 
ethernet driver for the EP93XX family and I don't see any changes 
required in the code to use the AC101L Phy. 

Currently the board only negotiates a link with some hubs, not all.  
Even after negotiating a link with a hub, the communications over 
ethernet is painfully slow, and eventually just dies.

I was wondering if anyone has some experience using this Phy with the 
EP93xx family or any other ARM based system?   Did you have to make any 
changes to the driver to use a different Phy.

We are currently chasing any hardware problems with the board that we 
can find.

Thanks for your help,
