Sounds like you need to boot via network (NFSroot) and need to use =

the "root-debug" directory instead of the "root" one as the root filesystem.

"root-debug" still contains all debug info.

Debug info for the main glibc is a different issue. This would drastically =

increase the binary, so it is disabled by default.
When building the toolchain you can enable a special menu entry to keep the =

debug info also for glibc (read its help!):

ptxdist menuconfig
  misc                          --->
   [*] debuggable toolchain internals

Juergen
