You have to pass as address the entry point of the vxworks kernel. On my PPC405 board I had no problem with the following steps I have in my config.h a RAM_LOW_ADRS = 00010000 ; I did no call mkImage for my vxWorks (5.5.1), but copied it directly into the ram at an address which does not conflict with my RAM_LOW_ADRS e.g. loadb 0x00200000 then I call bootm 0x00010000 ; On the Yosemite PPC440EP evaluation board, my vxWorks (6.3) hangs too. I had not yet a chance to figure out why, but I think there might be some differences into how the HW is mapped into the memory space. Best regards Niklaus Giger
