Hello,

I have a question about your ffutoimg python script.

I don’t understand line 104, when you seek at the location where to copy the data in the final image:

imgfp.seek(CurrentBlockDataEntry.dwBlockCount*FFUStoreHeader.dwBlockSizeInBytes)

Indeed, you use “CurrentBlockDataEntry.dwBlockCount” but, I tried with a FFU (Xiaomi Mi4) and this value is always 0 or 1. Because “FFUStoreHeader.dwBlockSizeInBytes” is always the same, the final value is always the same.

Shouldn't we use “CurrentBlockDataEntry.dwBlockIndex” instead?

Hello, now using Python 2.7.9 for Windows this error is shown:

D:\raspberry_pi_2\win10_iot\Windows_IoT_Core_RPI2_BUILD
λ python ffu2img.py Flash.ffu Rpi.img
File "ffu2img.py", line 35
logfp.write('Exiting, incorrect signature: "' + signature '")
^
SyntaxError: EOL while scanning string literal

Thanks!

Tried ff2img.py, ran successfully. Put image file on RPi and it booted to windows screen then went blank.

Tried ff2img.py3, got this error:

GBMacBookPro:diskFormat grahambriggs$ python ffu2img.py3 /Users/grahambriggs/Downloads/Windows_IoT_Core_RPI2_BUILD/Flash.ffu RPiWindows3.img
File "ffu2img.py3", line 94
print((str(iBlock) + ' blocks, ' + str((iBlock*FFUStoreHeader.dwBlockSizeInBytes)/1024) + 'kb written '), end='\r')
^

Thank you

Also, The pylint in VS 2013 Python tools, wants all the Print statements wrapped in parentheses.

Hello,

I just tried running the script using the version from commit e667caf

Some environment information:

Hello

When I try to convert the Flash.FFU image in Windows with Python 3.4.3, the console (cmder) shows this error:

D:\raspberry_pi_2\win10_iot\Windows_IoT_Core_RPI2_BUILD
λ python ffu2img.py Flash.ffu RPi.IMG
File "ffu2img.py", line 20
print 'Input File: ' + ffupath
^
SyntaxError: Missing parentheses in call to 'print'

I will try to run it on Linux.

Thanks.

Hello, I'm wondering if this works with the current versions of Windows IoT?

My goal is to make a NOOBS os image from a custom flash.ffu that can be used as a factory restore appliance for a Windows IoT running on RPi3.
