Hi All,

I am trying to modify the pin configuration inside the uboot because I would like to use my own expansion board rather than Toby board provided.

I was following a tutorial (http://www.jumpnowtek.com/index.php?option=com_content&view=article&id=55&Itemid=61) which explained me how to go about it. So, this is a quick summary of what i did -->

$ grep u-boot org.openembedded.dev/conf/machine/overo.conf
PREFERRED_PROVIDER_virtual/bootloader = "u-boot"

$ bitbake -c clean virtual/bootloader; bitbake virtual/bootloader
<change the overo.h file and generate the patch. The patch is finally put inside a folder called /recipes/u-boot/u-boot-git>
<edit the u-boot_git.bb file to add:
SRC_URI = "git://www.denx.de/git/u-boot.git;protocol=git \
file://pin/mux.patch" [I added this line myself]>

$ bitbake -c clean virtual/bootloader; bitbake virtual/bootloader

However, when I do the last bitbake to generate the modified u-boot, it gives me the following errors, and terminates bitbake:

shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
ERROR: [Errno 2] No such file or directory: '/home/c/overo-oe/tmp/work/overo-angstrom-linux-gnueabi/u-boot-2010.12+r75+gitr261733408a27d14590cf3ec6b596461808050e32-r75'

    def get_bbfiles( self, path = os.getcwd() ):

I have been stuck on this for quite a while and would really appreciate all your suggestions :)

Thanks and have a cheerful day!
