Decode ATMEGA162V Firmware downloaded from a device were the source code has been lost so it can be uploaded to another device and the code rewritten

[login to view URL]: Device signature = 0x1e9404 (probably m162)

[login to view URL]: safemode: hfuse reads as DA

[login to view URL]: safemode: efuse reads as FF

[login to view URL]: safemode: Fuses OK (E:FF, H:DA, L:FF)

It appears the firmware downloaded is scrambled using [login to view URL] [login to view URL] -v -pm162 -c usbasp -F -U flash:r:i:\salcom\decoder\[login to view URL]:r as the first part of the bin file should be the reset interupt

the first bytes should contain a Jump 940C it containt 0000 which is a no-opp

So either the device is protected or the extract command is incorrect
