KC868-A6 DS1307 Issue

[Senapsys]

Hi there

I'm glad to hear my bin file worked on your KC868-A6.

I successfully loaded your bin file to my KC868-A6 using that address and it returned the error "Couldn't find RTC".

To summarise:
 - my bin file works on your A6,
 - your bin file works on your A6
 - my bin file doesn't work on my A6
 - your bin doesn't work on my A6

I think the only conclusion we can now draw is that there is a fault with my KC868-A6.

What are the next steps?  How do I arrange to get a replacement?
