STVP 3.4.1 here.mbrusa said:The OptionByte.S19 files, option_no_prot.ihx, stock_36V.hex, with binary comparison are all different, but open with STVP GUI they are the same, I don't see the difference you have reported.
Maybe it depends on the version of STVP GUI?
I have version 3.2.7, what version do you use?
For me the file from eco-bikes and the one I backuped from my motor (48V) before doing anything else to it is identical. All bytes 0x00 except for byte 2 that is 0x28.
The option_no_prot.ihx on the other hand has all bytes as 0x00 which changes the settings of AFR5 and AFR3.
stock/eco-bikes:
option_no_prot.ihx:
However, my motor doesn't seem to care. Works fine as far as I can tell.
I notice that casainho's firmware doesn't flash data and option at all so couldn't we just skip flashing option bytes?
