Dear Frank: I cannot replace the vxWorks bootrom because I have no source and bin files of vxworks bootloader, I have even no the hardware diagram resource of my PPC 860 board. If I write the U-Boot into the rom, I most possible cannot bootup the board. How to download the U-Boot into RAM directly using the vxWorks bootloader, I tried to load the U-Boot ELF image but get the same result "starting at 0x280000 ..." then no response from the serial console. The only thing I can do is use vxWorks TFTP to download the ELF image for linux kernel or U-Boot into RAM. Can you tell me how to slove the U-Boot "starting at 0x280000 ..." problem ? thanks!

Do what I did: Replace the vxWorks rom with you u-boot and you can boot Linux or vxWorks with the same bootloader. __________________________________________________ Do You Yahoo!? Tired of spam?
