Hi Jon & Gerald

Thanx for the patches. The kernel compiles now well and even the download
to the SBC8260 seems to work. It downloads 2 sections, perfect.

After having copied parts of embed_config.c to my kernel I get:

[VxWorks Boot]: g 400000
Starting at 0x400000...

loaded at:     00400000 0040B278
zimage at:     0040B278 0047C37F
avail ram:     0047D000 01000000

Linux/PPC load:
Uncompressing Linux...done.
Now booting the kernel
<crash>


I think I better move to a later kernel than -test2 !


Thank you

<I expect the output of the kernel on SMC1.>


Questions:
1. Is my assumption right that I have to jump to address 0x400000 in order to start the kernel?
2. Dan mentioned that I have to start our stuff at 0x900000! How does this correspond?
3. I'm still using HHL1.2. Does this kernel work on my board? (It's the revision test2)
4. Does the kernel use SMC1 for the printk? I think yes!
5. Does the objdump look right?
