G.T.Power RC A606D temp over err

[Sipos Péter]

Hello!

The charger produces an error in the video. 

What can cause this error? 

I've soldered over that didn't help either. 

Can anyone help me?

 Thanks!

Hi,

that does not look like cheali firmware...

My guess is wrong NTC value, but who knows. User manual does not help? Did you do any HW mods?

Are you sure, that there is no temperature sensor on board?

Depends what do you mean by software update. Manufacturers usually does not provide FW updates for such device. Cheali FW may give more info about failure.

Have a look into docs. At first, your charger has to be supported. Then you need FW binary (self built or pre-built from repo). Hw debugger to load FW inside (refer to mentioned docs).

If MCU inside is supported (Atmega32 or M0517LBN), but your charger is not, it mas be compatible with some existing one. Adding support for new charger with supported MCU is possible.

As I did not get answer, I'll ask again:

Did you do any HW mods?

I didn't find it, I think the ic thermometer uses a datasheet he thinks has a sensor in it.

update. Manufacturers usually does not provide FW updates for such device. Cheali FW may give more info about failure.

Then this is irrelevant.

>Did you do any HW mods?

No changes were made. I also mean that the calibration is set to the value and I think the temperature is high.
Is it possible to reboot somehow? I also connected it to a serial port, unfortunately it makes no sense to come in. And yet I tried all the speeds.  ⸮ ⸮⸮⸮⸮ enter such. Almost all speeds.

External temperature measurement and serial communication use same pin (AFAIK). You have to disable temperature monitoring before connecting serial. Otherwise it could cause some temperature measurement issues like you see.
