</div>Judging by the description on the afformentioned page, the fs.plc file<br>
has the format described at <a href="http://wiki.laptop.org/go/OFW_NAND_FLASH_Updater" target="_blank">http://wiki.laptop.org/go/OFW_NAND_FLASH_Updater</a><br>
<br>
It is basically a script used by OFW during the update process to build<br>
any partitions on the NAND and to validate the eblocks. The bulk of the<br>
script is a bunch of sha256 digests for each 128KiB piece (erase-block,<br>
or eblock) of the image you're flashing. You can see such scripts by<br>
unzipping an fs.zip from one of our signed builds and examining the file<br>
data.img.<br>
<br>

Ironically I just built a simple script to generate such files because<br>
it will help us in getting your custom images ready for secure reflash.<br>
Instructions regarding that process will be forthcoming this afternoon.<br>
In the meantime I suspect you can resolve the NANDBlaster issue by using<br>
the script.<br>
<br>
You can obtain the script from:<br>
<br>
git-clone git://<a href="http://dev.laptop.org/users/erik/image-digestor" target="_blank">dev.laptop.org/users/erik/image-digestor</a><br>
<br>
Run it as follows against the image file you are trying to NANDBlast:<br>
<br>
image-digestor.sh <image_file_name><br>
<br>
After a minute or so it will produce a file called<br>
<image_file_name>.ofw_update_script. Rename this file fs.plc, put it on<br>
the USB alongside fs.img, and start the NANDBlaster again by following<br>
the instructions on the Multicast NAND Updater page.<br>
<br>
Hopefully that resolves the issue. Please indicate if you encounter<br>
more problems.<br>
<br>
Best,<br>
