This is a FAQ. Please see http://www.denx.de/twiki/bin/view/DULG/EthernetDoesNotWorkInLinux
Actually, in the case of the Innovator OMAP1510, the Linux smc919x or smc9194 driver (depending on which you're using) should do the right thing independent of u-boot. Perhaps you don't have the SMC91C96 DIP switches set correctly on the Innovator break-out-board. Mine are SW1 1,2,3 OFF, 4 ON. If those DIP switch settings are wrong, then the SMC91C96 serial EEPROM may be disabled and this u-boot dependency may be a side effect since u-boot doesn't use the serial EEPROM MAC address. Then again, I haven't tested booting Linux w/o first doing u-boot bootp/tftp lately. So maybe there is a regression in the Linux network driver(s). : P Also, some early Innovator BOB's didn't have serial EEPROM MAC address programmed which may also cause this problem. If the Innovator BOB has MAC address label attached to it (mine is lower right corner below the power supply binding posts) then the serial EEPROM MAC has most likely been programmed at the factory. Else, you'll need to program the serial EEPROM yourself. IIRC, others have posted tools to set the serial EEPROM MAC address.
HTH!
