[U-Boot] [PATCH] common/image.c: Relocate strings in tables.
by Scott Wood 17 Mar '09

When "something is wrong within TFTP", the respective function returns an error code, which propagates upward and causes the running command to terminate, so you automatically end up back in the U-Boot shell. Maybe you should explain what exactly you are trying to do. I have the feeling that your question does not describe your actual problem, and that your actual problem might be either be based on a misunder- standing or inappropriate use.

[U-Boot] [PATCH] Make nboot skip bad blocks

[U-Boot] Generic MII interface
by Remco Poelstra 17 Mar '09

17 Mar '09

Hi, While working on cleaning up my LPC2468 port, I was wondering whether I'm correct in thinking that U-boot has some generic MII interface? My processor has a MAC which uses (R)MII to communicate with the PHY. Can I adapt my MAC driver for such interface, so the MAC and PHY code can be separated? Kind regards, Remco Poelstra

[U-Boot] Cleaning up new port
by Remco Poelstra 17 Mar '09

17 Mar '09

Hi all, I've finished my port of U-boot 2008.10 to the LPC2468. I've based my port on code by Embedded Artists, which was based on U-boot 1.1.6. The LPC2468 is an ARM processor with build in peripherals, so I need to divide my code into LPC2468 generic part and a part for my board only (which is not to be published). I have however no clue on how to do that. What code should belong where? Is there any documentation on the exact code structure of U-boot? Is anyone here interested in LPC2468 support and willing to offer some help? Kind regards, Remco Poelstra
