[ECOS] iq80310: pci_init_find_82559s() never returns

[Daniel Franke]

Hi there!

I got the eCos CVS tree, created a new config (ecosconfig new iq80310
net), set IP, subnet etc created the tree and build it with the tests.

--snipplet from ecos.ecc (export)--
cdl_option CYGDBG_DEVS_ETH_INTEL_I82559_CHATTER { user_value 1 };
cdl_component CYGPKG_NET_BUILD_TESTS { user_value 1 };
cdl_interface CYGHWR_NET_DRIVER_ETH0_SETUP {
    # Implemented by CYGHWR_NET_DRIVER_ETH0_MANUAL, active, disabled
    # Implemented by CYGHWR_NET_DRIVER_ETH0_BOOTP, active, disabled
    # Implemented by CYGHWR_NET_DRIVER_ETH0_ADDRS, active, enabled
    # ...
}
cdl_component CYGHWR_NET_DRIVER_ETH0_BOOTP { user_value 0 };
cdl_component CYGHWR_NET_DRIVER_ETH0_ADDRS { user_value 1 };
cdl_option CYGHWR_NET_DRIVER_ETH0_ADDRS_IP { user_value 192.168.0.200 };
cdl_option CYGHWR_NET_DRIVER_ETH0_ADDRS_NETMASK { user_value 255.255.255.0 };
cdl_option CYGHWR_NET_DRIVER_ETH0_ADDRS_BROADCAST { user_value 192.168.0.255 };
cdl_option CYGHWR_NET_DRIVER_ETH0_ADDRS_SERVER { user_value 192.168.0.1 };
cdl_option CYGHWR_NET_DRIVER_ETH0_ADDRS_GATEWAY { user_value 192.168.0.1 };
--end--

Running the "server_test" (or any other, no difference in result):
--cut--

pci_init_find_82559s()
--cut--

That's the end. The 7-segment display shows '02' (instead '01') and I get
no more response.
(I'm not used to gdb, I just followed the doc to get here.)


The target is a iq80310, Rev. F.
A previously installed Linux works with the NIC - but only if 'diag' is
started before and it has done its reset. Now the NIC is recognized by
RedBoot - and later by Linux. If I run Linux at once (without calling
diag) neither NIC nor PCI bus are recognized.

--RedBoot (reset after diag)--

--end--

Has anyone got eCos on IQ80310 using the internal NIC running and may
help?

Thanks in advance!

Is this in a PC or backplane? We've heard of conflicts with the PC Bios
before - if it's in a PC make sure S3-2 is off.

Alternatively there are some fixes we've made to the iq80310 that may help
this, however they aren't public yet until eCos v2 (which is now being
actively worked on again!)

I had the same problem. IQ80310 is plugged in a PC at 32bit/33MHz PCI bus.
I tured off S3-2.
After download Redboot RAM start version, it hangs after
pci_init_find_82559s().
For further debug, it hangs at pciwindow_mem_alloc().
