1 ''' 2 Some bootloader's support hashing partitions. This is a great feature for testing 3 correctness. However, the format for the way the hash is returned depends on the 4 implementation. The hash could be send through an INFO response, or be as part 5 of the OKAY response itself. This script is called with the first argument 6 as the string mesage from the okay response. The second argument is each 7 info response joined by newlines into one argument. 8 ''' 9 10 import sys 11 12 13 def main(): 14 ''' 15 Data is sent back to the parent fuzzy_fastboot process through the stderr pipe. 16 There are two interpretations of this data by FF. 17 18 0 return code: 19 Anything written to STDERR will be interpreted as part of the hash. 20 21 non-zero return code: 22 Anything written to STDERR is part of the error message that will logged by FF 23 to explain why hash extraction failed. 24 25 Feel free to print to to STDOUT with print() as usual to print info to console 26 ''' 27 script, response, info = sys.argv 28 # the info responses are concated by newlines 29 infos = [s.strip() for s in info.splitlines()] 30 sys.stderr.write(infos[-1]) 31 #print("Extracted checksum: '%s'" % infos[-1]) 32 # non-zero return code signals error 33 return 0 34 35 36 if __name__ == "__main__": 37 sys.exit(main()) 38
