RE: Problem with cuImage Linux entry from old U-boot

Thanks Scott for the tip. I'll redouble my efforts to compare the code
in my older 1.1.2 U-boot source (that the board boots from) with my new
.dts and cuboot source.

I have made great strides with help from this mailing list and its

I'm not sure if I'm trying to jump into the kernel at the wrong

or if I have a serial console issue that prevents me from seeing

Most likely the latter, or some other issue that prevents the kernel
from
booting to the point where the serial console functions.

If I run 'nm' on my elf image, I expect to find some entry point

that corresponds to 0x7423a0, but this is not the case.=20

Why would you expect that?  It's a dynamically allocated chunk of memory
that holds the device tree that is passed to the kernel.  It's not an
entry
point; the entry point to the kernel is zero.
