[U-Boot-Users] MPC8280 mkimage: "...has invalid buffer for XIP"

[KokHow Teh]

Hi;
      I read the mkimage output again and found out the "-x" option. I
tried it out and have the following error.

[teh at ShrekII inetutil 67]$ $OBJCOPY -O binary -R .note -R .comment -S rom.elf inetutil.bin
[teh at ShrekII inetutil 68]$ mkimage -x -A ppc -O psos -T kernel -C none -a 0xff800000 -e 0xff800040 -n uImage.psos -d inetutil.bin uImage.psos
mkimage: Bad file: "inetutil.bin" has invalid buffer for XIP
[teh at ShrekII inetutil 69]$

      Any insight is appreciated.

Regards,
TEH

Subject:    [U-Boot-Users] MPC8280 bootm XIP


Hi;
      My initial binary image for MPC8280 has .text begin at 0xff800000 and
_START (entry point) at 0xff801004. However, after mkimage, this original
memory locations have been offset by 64 bytes. The image is loaded into
flash memory at 0xff800000. My question is how, if it is possible that I
can execute-in-place my application+psos kernel with bootm from u-boot?
Isn't "-a <load address>" of `mkimage` command meaningless in XIP
situation?

[teh at ShrekII inetutil 59]$ mkimage -A ppc -O psos -T kernel -C none -a
0xff800000 -e 0xff801004 -n uImage.psos -d inetutil.bin uImage.psos
