Hi all, I'm trying to port uboot and linux on a Avnet fx12 mm. Thanks to Llandre for his mmfx12  patch. And i also used the ll_temac driver. So uboot is running with network. I built linux using the xilinx kernel (git://git.xilinx.com/linux-2.6-xlnx.git). I can start it using XMD but not with uboot. So my question, Did someone already the same job ? I'm a newbie, so every tip is welcome The main aim of the system is to achieve a fast Ethernet connection > 15 MB/s Architecture on the virtex 4 FX and mapping ppc405 DDR_SDRAM      0x00000000 0x03ffffff FLASH_2Mx16     0xffc00000  0xffffffff xps_intc_0   interrupt controller TriMode_MAC_GMII RS232  using xps_uart16550 PLB Bus I have built u-boot 1.3.3.rc3 Linux kernel is 2.6.25-xlnx Thanks Simon Frey
