I have a lot of modules with the GigaLight brand. I need to modify the code in them, but they are protected by a write password.
I try to search password by bruteforce password finder. I set the password location at A2h, 7Bh, access type to Manufacturer, range 80 00 00 00 - FF FF FF FF (in accordance with the MSA standard) and I left checked "Apply range to single bytes" (which is the default setting).
Speed of password searching is approx 1660/s - ie password search took approx 15 days. Unfortunately, the password wasn't found.
O.K. - I can try search password with unchecked "Apply range to singele bytes" (15 more days), or I can try search password in range 00 00 00 00 - 7F FF FF FF with and without checking "Apply range to singele bytes" (30 more days). That's quite a lot of time. Therefore, I would like to ask if any of you know the password I search. Or at least some more accurate range in which it is appropriate to look for.
Alternatively - is it possible that the password is located at some address other than the A2h, 7Bh?
Or where else can there be the snag?
