[U-Boot] Help with u-boot and network on SDP4430 (Blaze) platform
Hi, I am having few issues that I am having with u-boot and linux kernel, and I do not understand it. For example, If I use latest u-boot, compile it natively for sdp4430, it boots the 26.6.38 kernel, however network interface(eth0) is missing. Even if I modprobe KS8851 driver the interface is missing, so there is no network. If I use older u-boot that is working on blaze platform, Network is foun when the kernel boots boots up, but kernel hangs later on . But latest u-boot and any kernel works on panda board. It always has network initialized and kernel boots. I looked around the u-boot code/config (for panda and blaze), but I did not see anything that can be causin network interface to come up or kernel to hang. Googling around showed some chage to TEXT_BASE address. So I tried it, but then u-boot did not work anymore. I am a lot confused as to how MLO, u-boot, and kernel are dependent on what each one does. Any help with this is very much appreciated. Best Regards Miko ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
Re: [U-Boot] Help with u-boot & linux on walnut based board.
Thanks Wolfgang, I looked at the code more carefully and found that I actually commented out a portion of the code that copies the emac address in linux. My initial port was using Linux 2.4.20 and the code was not there in that version. Since I'm now using 2.4.25 (ELDK 4.1 would not compile the old kernel), when I ported my changes over, I missed that there was a new line of code added to board_setup_arch function. Anyway, after fixing the problem, it is working again. Thanks again. Brian At 12:15 PM 8/19/2008, Wolfgang Denk wrote: >Dear "Brian S.

MAC address passing from U-Boot to Linux hjas nothing to do with the PHY used. In 2.4 you're using the bd_info structure to pass this information. Your Linux network driver should pick it up there; in 2.6, you should use the device tree - again, your Linux network driver should know where it can find the MAC addresses.

[U-Boot] Help with u-boot & linux on walnut based board.
Hi all, I'm having trouble witn my network interface under linux and need some help from the experts here. My board is based on IBM walnut (PPC405GPr) but uses a different phys chip. It is using DP83848 instead of DP83843. The network seems to work find in u-boot (both 1.3.1 and 1.3.4) but the linux is not getting the MAC address correctly. The address is set in u-Boot but the linux reports 00:00:00:00:00:00 I'm using linux kernel 2.4.25. Do I need to use kernel 2.6 to use the newer phys chip? Any pointer would be appreciated Thanks.
