Re: U-Boot and kernel 2.6

Hi Ricardo,

I would recommend not to try old versions of U-Boot ("from 2.4") with new 
linux kernels ("2.6").
We had some troubles with invalid memory mappings in this configuration.

Hi,

I'm trying to boot a custom 860T board using the latest kernel from
linuxppc-2.5. The board is currently using a variation of an old version
of U-Boot (0.2.0) along with a hacked 2.4.20 linux kernel version.

My first aim is to boot a simple kernel and make it get to a shell. For
that I compiled the kernel, but did not compiled u-boot with a recent
version.

When booting, the kernel got uncompressed, but then it resets! I presume
the watchdog (which is enabled), is resetting the processor, so I guess
booting just stalls. Was there any changes in the way parameters were
received by the kernel since 2.4.20?

Oh, I forgot to mention the compiler. I'm still using a gcc 2.95
cross-compiler, altough I tried using a gcc 3.2 cross-compiler for the
8260 once, but got the same result.

I followed a recent thread very similar to this, but that turned out to be
just a matter of UART configuration, and I don't thinks this is the case.

Any thoughts?

Thanks in advance,
Ricardo Diz
