sfox7076, your goods are on the way. Next week I'll check status and provide you tracking. Now I'm in another city.

David880, Your Maya was missing a high power relay. Monday I'll give you tracking as well.

There is one package returned from UK !!! Again, Monday I'll check status and reship.

Don't worry, all orders will get final destination.

Regards,
Tibi

Hi Tibi. I just finished my amplifier and got a little problem.
The Maya is stuck in an overheat warning after the speaker check. What could cause this?
It's not hot. actually the amp doesn't even start. I also detached the temperature sensors but it's still the same.
Help would be nice 🙂

So it is a software bug. I Actually thought maybe one of the temperature sensors was not ok, but they are provided witz 4.87V and put 0,66V out on the Sernsor line. So that should be fine.
So I need a JTAG then it seems? Or ios there a possibillity to progremm it with the atmel stk500? Havern't worked with it for some time so I'm not sure .
Thanks for the help.

Edit: Just seen you use the ISP. So I should be fine with the stk500 🙂

Hi there.
It is not a bug , it is a feature , it means that he cannot communicate with one or both temperature sensor .
Please check connection to both temperature sensor (maybe you insert wrong the temperature sensors?).
After communication will be ok it will let go further.
Maya cannot work without temp sensors (when enabled by default from settings menu) and if you have not connect both sensors will show that message.
Please check also polarity on sensors (very important : you will see + and - on both boards and on LCD board please check that).
(You can disable temperature monitoring in the setting menu but for this the communication with sensor must be working first ...)
