[ECOS] RealTek 8139 Redboot i386

[ECOS] RealTek 8139 Redboot i386

[Vijai Krishnamurthy]

I'm a newbie to eCos....need some help here.

I'm trying to bring up a i386 target booting from a Redboot floppy with
network support.
I used Chris Paulson's Realtek 8139 driver and followed the instructions for
the ecos config.

Once I boot the target I get this message and the machine just hangs:

DP83902A eeprom: ESA: FF:FF:FF:FF:FF:FF

I suppose this error message has got to do with the MAC address reading
(correct me if I'm wrong). Now do I have to set the hw address manually? If
yes where? Most of the other network drivers do have the option of setting
the address manually but not the realtek one.
Am I missing out something here?...may be somehting got to do with ISA vs
ESA??

Help in this regard would be gratefully appreciated.

Thanks and regards,
Vijai

DP83902A is software compatible with Realtek 8039AS (essentially an NE2000).  
I don't believe that a driver written for an DP80902A could work with an 
8139.  That one requires a dedicated driver, that's the way it's done in 
other OS-es (Linux, FreeBSD).

Hi,

The driver on www.edesix.com/ecos is for the 8019AS ISA chip, not the 8139
PCI chip.

We recently had a customer who wanted us to write a 8139 driver, which would
have been contributed, but they baulked at the (very reasonable) cost. If
someone else wants to pay for it, please drop us a line.

Chris.

Oh, is there any chance you could fill in a proper assignment form? We 
can't just go on "Redhat can consider the copyright on my changes as 
having been assigned to them, as far as I'm concerned." unfortunately, 
nice and easy though that would be!

Your changes to if_dp83902a.c should be alright without an assignment. Any 
chance of submitting that (with ChangeLog possibly?) to 
ecos-patches@sources.redhat.com? That would also be excellent. Although I 
don't know where BIGENDIAN gets defined. I assume that should be 
CYG_BYTEORDER == CYG_MSBFIRST.
