Dear David,

I am trying to bring up an uImage made from a Timesys 4.0 kernel on a EP860 board with u-boot 4.0 as the bootloader. I did a small port to make
U-Boot 4.0? Wow! You must be living in a far future.
We're stills tuck with version 0.4.x ;-)
I copied the bd_info structure from u-boot.h to rpxclassic.h in the kernel
This is wrong. You should include ppcboot.h in rpxclassic.h.
When I try autobooting the kernel image from the tftp server, it hangs soon after the kernel is uncompressed.
...
Load Address: 00100000 Entry Point: 00100000
This cannot work. The powerpc kernel requires load address == entry point = 0x0000.
I had to move the load address up from 0x0 to pass the uncompressing stage.
You added another problem instead of solving the first one.
I'm not sure why loading to 0x0 causes problems since the examples in the readme all use 0x0 as the load address.
0x0000 is needed.
I made the uImage from vmlinux in the top level directory and the vmlinux.gz from arch/ppc but they hanged at the same point.
Did you read the README? You should.
I would really appreciate any suggestions you can give me to try on the
RTFM.
Best regards,
Wolfgang Denk
