ocm_spi_mmu problem with NEEK

Hi

I'm newbie and I want to make my NEEK working with MMU. I follow the tutorial in the NIOS wiki for the toolchain installation (I have Fedora 10).

I succeded with my first project starting from scratch (only cpu and UART), so the toolchain is working and now I want to implement ethernet.

I look at the Ethernet page on the wiki and for testing I download the ocm design for neek (neek_ocm_spi_mmu.zip). I take directly the custom_fpga and I try to configure the drivers (make menuconfig) and I have some difficulties to choose the drivers. I look at the thread "Avalon OpenCores MAC 10/100 + µClinux" thread 18390 and I configure the drivers accordingly. Anyway when I do "make" I have the following error :

/home/phil/nios2-linux/linux-2.6/drivers/net/open_eth.c: In function 'oeth_phymac_synch':

/home/phil/nios2-linux/linux-2.6/drivers/net/open_eth.c:757: error: 'PHY_ADDRESS' undeclared (first use in this function)

/home/phil/nios2-linux/linux-2.6/drivers/net/open_eth.c:757: error: (Each undeclared identifier is reported only once

Why this error?

Antoher question more generic: where to find the driver to configure with the sopc modules I implement? I mean when I looked at the ip eth_ocm documentation I can't find the relevant options to cross in the "make menuconfig"

Finally, I looked at the sopc configuration for the ocm_spi_mmu project and I'm wondering about the IRQ0 for the sys_clock_timer ??? I thought it as forbidden ???

Thanks

    please use ethoc for nios2mmu branch. The open_eth in nios2mmu branch is not updated yet.

    sys timer can use irq0.

    Please check nios wiki for driver info.

    Thanks Hippo, it's now working.

    Anyway I have the same issue as other people, with RX : overrun and packet dropped. I use ethoc in static IP, with route and gateway configured. What is amazing is that overrun and packet dropped messages appear only when I connect the NEEK to my lab network. When I use only a ethernet "cross" cable between my pc and the neek, this error disappears !!!! Any idea ?

    Another issue is now to configure the framebuffer. I use the Framebuffer wiki page and I guess the fb0 is working because the neek screen as color bars. But if I want to use Microwindow and specially nanox, I have the jpeg error:

    /usr/lib/libjpeg.so: could not read symbols: File in wrong format

    collect2: ld returned 1 exit status

    make[5]: *** [/home/phil/nios2-linux/uClinux-dist/user/microwin/src/bin/nano-X] Error 1

    make[5]: Leaving directory `/home/phil/nios2-linux/uClinux-dist/user/microwin/src/nanox'

    I looked at the jpeg library and it's automatically selected.

    I tried to not use jpeg (png for instance) and I have a equivalent problem.

    I'm stucked.
