the logfile name is

Traceback (most recent call last):
  File "/home1/llin/shangr/bitbake/bin/bbimage", line 150, in <module>
    bb.build.exec_func('image_cmd', localdata)
  File "/home1/llin/shangr/bitbake/lib/bb/build.py", line 100, in exec_func
    exec_func_shell(func, d)
  File "/home1/llin/shangr/bitbake/lib/bb/build.py", line 168, in
exec_func_shell
    so = file(logfile, 'w')
IOError: [Errno 21] Is a directory
========================================

in fact the log file is not a directory,as you see the first red line ,
note:before do_rootfs ,i add a function to IMAGE_PREPROCESS_COMMAND to clean
.debug files
ps 1 :if i remove this clean debug function,it is ok

I am not sure whether it belongs to OpenEmbedded or bitbake isssue

thanks
