Xilinx board and NPTL support lockup
Hi everyone,
I have a board similar to the ml410, its been running a linux kernel happily for about a year now, but now the firmware guys want NPTL threading instead of the linuxthread library.
I recompiled my gcc 4.0.2 and glibc 2.3.6 library with the NPTL support, and recompiled my kernel with the new tools.
Now my kernel gets stuck at the infamous "Now Booting the Kernel" message.
Any thoughts on why this might be happening, or how to verify that my glibc and gcc are functional other than trying to compile things with them (I know this works).
Thanks
Kevin

Hi Kevin,
This doesn't look like an NPTL problem to me. It appears you have rebuilt the kernel, and your new kernel has a problem booting on the board. I would check the configuration options you have enabled in the kernel, and I would check that xparameters.h (older kernel) or the device-tree (newer kernel) is right for your hardware design.
If you haven't rebuilt the kernel, then I would check your setup.

Thanks for your help.
This was a kernel setup issue, I had forgotten to strip the debug informati= on out of my new libraries and my initramfs was too large.
I believe the zImage was decompressing onto itself, thats why it was stuck = at the "now booting." I probably could have fixed it by changing my boot l= ink/load address in the kernel config but I just stripped the files and it = booted fine after it was smaller.
Hope this helps out anybody else with similar problems.
Kevin
