I have built uboot, it boots up fine. Only problem is the console is set to screen.(via of serial port). I want redirect the console to my serial port, which file should I change?

[U-Boot-Users] Redirection via serial port

Hi, I am working in MPC5200B powerpc. I suppose to use UBoot as the bootloader. I want to know how to redirect stdin, stdout, stderr during boot to serial port. Tell me where I have to make the necessary changes in the bootloader.

[U-Boot-Users] Linux on IXDP425
by Ori Idan 12 Jul '07

I have U-boot compiled for IXDP425 (version 1.1.6) I am trying to use it to load MontaVista kernel 2.6.10 on this board. U-boot get to the stage where it says "Starting Linux kernel" and the board hangs up. Following is the log of U-boot output. I hope someone on this list have experience with this. The uImage was built from zImage, we tried building it from other compiled images but got the same error.

[U-Boot-Users] [PATCH 16/17] mpc83xx: Replace fdt_node_offset() with fdt_find_node_by_path().
by Jerry Van Baren 12 Jul '07

12 Jul '07

The new name matches more closely the kernel's name, which is also a much better description. These are the mpc83xx changes made necessary by the function name change.

Please review. Because these are required companion changes to the fdt patches (or the build will break), I would prefer you to ACK the changes (assuming they are OK ;-) and have Wolfgang pull them from the u-boot-fdt repository. Alternatively, you could apply them and push them through your u-boot-83xx repo, but that would cause compilation breakage until both patch sets are applied.

[U-Boot-Users] [PATCH 0/5] Generic PCI-E changes for relative bus numbering
by Jon Loeliger 12 Jul '07

12 Jul '07

Folks, The following 5 patches from Ed Swarthout changes how PCI-Express bus numbers are assigned such that P2P bridge] bus numbers programmed into the device are relative to hose->first_busno. The first patch ensures that the hose->current_busno is not less than first_busno. This fixes broken board code which leaves current_busno=0 when first_busno is greater than 0 for the cases with multiple controllers. Minor improvements to some DEBUG() output are also added. Two generic PCI functions are un-static-ized for use in my follow up patchset for the 86xx platform. I've only been able to test this on a limited number of boards with PCI-Express support, so anyone else who can verify these changes would be appreciated. Thanks, jdl PS -- Look!
