Problem with extracting bin file #59

Closed eagleman111 closed 6 years ago

eagleman111 commented 7 years ago

Hi, I am trying to extract bin file by running "python amba_fwpak.py -vv -x -m fw.bin" seems it fails and this is the result: fw.bin: Opening for extraction fw.bin: Header: { 'crc32': '52503030', 'model_name': b'xV4\x12' b'\x01', 'ver_info': '54.69-4349'} fw.bin: Detection finished with entry larger than file; expecting 1 entries fw.bin: Warning: Detection finished with unusual condition, verify files fw.bin: After detection, expecting 1 entries fw.bin: Entries: [{ 'crc32': '5053000C', 'dt_len': 79}] fw.bin: Post Header: { 'part_size': '502b098b ' '0000098b ' '00000000 ' '00000000 ' '0001003a ' '010a0005 ' '000002b2 ' '0000a2e8 ' '0000a2e8 ' '42ec6231 ' '6f4cc0e1 ' 'cd35c144 ' '76d1db20 ' '42ec6231 ' '6f4cc0e1'} fw.bin: Warning: Invalid magic value in partition 0 header; will try to extract anyway. fw.bin: Entry 0 { 'build_date': '1-00-29', 'crc32': 'CD35C144', 'dt_len': 16777226, 'flag1': '0000A350', 'flag2': 'CF3CF4DE', 'magic': '0000A350', 'mem_addr': '0000A59A', 'padding': 'a1abed14 ' 'ab584309 ' '76d47c45 ' 'cf3cf4de ' 'a1abed14 ' 'ab584309 ' '76d47c45 ' '00011019 ' '03020ffe ' '000148ea ' '00140300 ' '00140300 ' '1363f4b6 ' 'c7e68699 ' '158aa9ac ' 'ae3c7f83 ' 'aa01b1f7 ' 'f77bed82 ' '02dd09fa ' 'c58b8de1 ' '0001000b ' '01010323 ' '00154bea ' '00008f5d ' '00008f5d ' 'c89251f8 ' 'da4eedb2 ' 'efdc210b ' 'a1b53c3f ' 'c89251f8 ' 'da4eedb2 ' 'efdc210b ' 'a1b53c3f ' '0001002b ' '00070f00 ' '0015db47 ' '000056a0 ' '000056a0 ' '1179a648 ' '99119989 ' '2e383858 ' '671d5267 ' '1179a648 ' '99119989 ' '2e383858 ' '671d5267 ' '0001004b ' '00070f00 ' '001631e7 ' '000056a0 ' '000056a0 ' '1179a648 ' '99119989 ' '2e383858 ' '671d5267 ' '1179a648', 'version': '30417.56096'} fw.bin: Extracting entry 0, pos 108, len 16777226 bytes fw.bin: Warning: partition 0 truncated, 3210405 out of 16777226 bytes fw.bin: Warning: Entry 0 data checksum mismatch; got 37CD7A27, expected CD35C144. fw.bin: Warning: Entry 0 cummulative checksum mismatch; got 3C94CF30, expected 5053000C. fw.bin: Warning: Entry 0 date makes no sense. fw.bin: Warning: partition 0 header uses values from padded area in an unknown manner. fw.bin: Warning: Total cummulative checksum mismatch; got C36B30CF, expected 52503030.

Any help?

Your fw.bin is clearly not the file you can extract with this tool.

eagleman111 commented 7 years ago

it is the "MATRICE600PRO_FW_V01.00.00.80.bin" file from "supported_firmwares.csv" from your repository

mefistotelis commented 7 years ago

Why do you want to extract it with Ambarella extractor?

eagleman111 commented 7 years ago

I want to extract it to be able to edit parameters, and discover it

mefistotelis commented 7 years ago

ok, then you should probably use a correct extractor. The firmware package you're trying was not made by Ambarella.

eagleman111 commented 7 years ago

mmmmm, so your tools are not compatible with m600pro?

mefistotelis commented 7 years ago

All the firmwares within supported_firmwares.csv are supported.

eagleman111 commented 7 years ago

the "MATRICE600PRO_FW_V01.00.00.80.bin" file from "supported_firmwares.csv" however it is not extracting. Any help?

mefistotelis commented 7 years ago

I'm getting mixed messages from you. The struggles you're having suggest you are not up to the task, but if you're working on Matrice platform, you should have at least a basic technical knowledge.

I will assume you just had a bad day or temporary mind freeze. Here's your answer:

Ambarella chips are used for cameras, like Action Cams and also the cameras mounted in DJI drones. What you have there is a firmware package for the whole DJI drone, not for Ambarella camera. The firmware package was made by DJI. You have to use DJI extractor on that firmware. If there is a camera module firmware within the DJI firmware package, then you could extract it as next step - but you mentioned you want to edit flyc_params, which has nothing to do with camera.

After you extract the modules, you can look at this project wiki for details of each module.

1-I got you, so all dji drones which dont have camera installed with it, no need to use amba_&.py, right? 2- I extracted the bin file and now have the modules, ande trying to extract the parameter file by this command "dji_flyc_param_ed.py -vv -x -m fw_m0306.bin" It show me that "Flight controller parameters array signature not detected in input file" This is the log file: fw_m0306.bin: Opening for extraction Traceback (most recent call last): File "dji_flyc_param_ed.py", line 630, in main(sys.argv[1:]) File "dji_flyc_param_ed.py", line 611, in main flyc_extract(po,fwmdlfile) File "dji_flyc_param_ed.py", line 475, in flyc_extract raise ValueError("Flight controller parameters array signature not detected in input file.") ValueError: Flight controller parameters array signature not detected in input file."

mefistotelis commented 7 years ago

Do you have the module unencrypted?

eagleman111 commented 7 years ago

I dont think so, all what i did is extract the bin file, then run the "dji_flyc_param_ed.py -vv -x -m" on "fw_m0306.bin" file, Do I have to decryot it first? and how?

mefistotelis commented 7 years ago

We don't have a key. You need decrypted module. Hope you are reading details about this module on the wiki.

eagleman111 commented 7 years ago

I read alot wiki helped me alot, but not in decrypting it :( Any help?

mefistotelis commented 7 years ago

Have you seen the word "unencrypted" in some places?
