#fileformatanalysis — Public Fediverse posts

Hello fedi!

I have an .MVAX #firmware #update file for an MV Silicon chip (unknown model).

Has someone already encountered those? And if yes, is there some documentation, tooling or existing #ReverseEngineering work done of that format?

For the record, the file magic (first 8 bytes) is as follow:
4D 56 B5 58 05 01 13 00

And the end of the file contains the following (no spaces, wrapping is mine):

MVSKeyFileMVBP10<0x90>0xBE>SIMPLEs
<0xD3><0x9A>.<0x90><0xD9>
MVSILICONKEYFL<0x00><0x00>
<0xFF><0xBD><0x00>0x00>

Thanks in advance for your help!!
