[henry son]

Hi All,

I'm following the OTA tutorial from Android official source: https://source.android.com/devices/tech/ota/tools

I'm getting bellow error when do OTA generation, I'm sure that I have followed all pre-condition.

These are the commands:

make dist DIST_DIR=dist_output
./build/make/tools/releasetools/ota_from_target_files \
    dist_output/tardis-target_files.zip \
    ota_update.zip

Error output:

using prebuilt recovery.img from IMAGES...
Traceback (most recent call last):
  File "./build/make/tools/releasetools/ota_from_target_files", line 1532, in <module>
    main(sys.argv[1:])
  File "./build/make/tools/releasetools/ota_from_target_files", line 1487, in main
    WriteFullOTAPackage(input_zip, output_zip)
  File "./build/make/tools/releasetools/ota_from_target_files", line 486, in WriteFullOTAPackage
    system_tgt = GetImage("system", OPTIONS.input_tmp)
  File "./build/make/tools/releasetools/ota_from_target_files", line 316, in GetImage
    return sparse_img.SparseImage(path, mappath, clobbered_blocks)
  File "/home/android/fresh_android_8/build/make/tools/releasetools/sparse_img.py", line 51, in __init__
    raise ValueError("Magic should be 0xED26FF3A but is 0x%08X" % (magic,))
