You are right.. Best regards, Stefano Babic As said I'm trying to enable enc28j60 in beagle C4. The device did not gets initialized because in eth.c, the board_eth_init function is defined as __def_eth_init through an __attribute__ weak statements (always return -1). This is because in board/ti/beagle.c no board_eth_init function is defined and libbeagle.o is not linked to libnet.o (where board_eth_init gets called). My question: have I to implement that function myself? Is it worth to introduce a new #define statements in omap3_beagle.h that enables the function in board specific file? I will be happy to do so, if it's worth (I'm looking at top900 board specific file as an example). Thank you ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Best Regards, Reinhard Yes, I have CONFIG_NET_MULTI (mainly I've taken those entries from top900 and lpc2292 configs).

Best regards, Stefano Babic GOSH, I've exactly searched through the code for CONFIG_CMD_NET, but I did not noticed was an undef statment instead of a define! Everything's fine now. Thank you. Just another question. I've studied the linux enc28j60 driver and noticed it features an interrupt driven work flow. No interrupt are used in u-boot version (for what I've seen). Is it based on some sort of polling instead of interrupt? Isn't that dangerous? I mean, if there are no data available everything is going to freeze..

No interrupt are used in u-boot version (for what I've seen). That is correct. As u-boot is a bootloader and no os, everything can be done in a single task and polling is used when it is needed.
