In early 2.6 kernels, support for 8xx was more or less broken. Lately, it has become clear that ARCH=ppc is a dead end and things should move to ARCH=powerpc. That's why I said we (DENX) will not support the 8xx in the ARCH=ppc context. Last but not least I would like to remind you that 2.6 is bigger and slower than 2.4, which is especially visible on low end systems like the 8xx. The kernel code that comes with the ELDK is very close to the vanilla kernel.org tree (plus some local extensions that have not yet been pushed upstream). The 8xx support in both trees is absolutely identical, i. e. the fact that 8xx code is in the ELDK has the very same reason why x86 code is there, or why sh4 or etrax or ... code is theee, even if these systems are not supported by the ELDK at all - this code is part of the vanilla kernel.org tree. AFAIK, 2.6 has never been fully ported to the TQM8xxL and TQM8xxM systems yet.

Simple applications don't need no libm. Neither libc nor libstdc++
per se require libm.
It is your code and the library functions you call which causes such
dependencies. Note that you have to be aware that even innocent
looking calls like a
printf ("Hello World\n");
may be the culprits
Example:
-> cat foo.c
#include
int main (void)
{
(void)write (1, "Hello World\n", 12);
return 0;
}
-> export CROSS_COMPILE=ppc_6xx-
-> ppc_6xx-gcc -Wall -pedantic -o foo foo.c
-> ppc_6xx-ldd foo
libc.so.6 => /opt/eldk/ppc_6xx/lib/libc.so.6
ld.so.1 => /opt/eldk/ppc_6xx/lib/ld.so.1
You see: no libm needed.

You are right. For a permanent patch that would be better - in our case it was important to be able to turn on and off this workaround dynamically with exactly the same kernel binary.

No, this is not a toolchain issue. It's a processor problem. I have to admit that I didn't believe our customer when he reported that he has problems that were caused by the CPU15 bug - I never saw this on any other 8xx processor before, and as you say it has been mentioned in all errata sheets I can remember. As far as I can tell it is only the MPC870/885 duet family of processors where this CPU15 bug actually hits. I have no idea why.

If this is by any chance under U-Boot, then you should read the docs how to convert a plain ramdisk image like the one you are using into a U-Boot image (hint: use the mkimage tool).

TFTP not able to find file???

When you use DHCP or BOOTP you ask for network configuration from the server, so this is what you get. > BOOTP command seems to be the only way to kick off tftp, so I really Wrong. You can start in manually (using the "tftp" / "tftpboot" command, or automagically as part of the "rarpboot", "bootp" and/or "dhcp" commands. > wasn't able to find a way to make use of statically set network > Config info.
