I have a working system, PowerPC embedded in Xilinx Virtex II Pro, that does boot into Linux using u-boot 1.1.3; but I need to load a VxWorks (6.3) image and boot from that. I have read the documentation, but I don't know what my entry point for mkimage to use, sysInit( )? What should my load address be?
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.
