TX does not save settings.

[kmargos]

Hello everyone,

I'm using the M2561, ER9x, r821, Frsky mod.

When a TX setting is saved, the TX flashes and returns to the main display.
The same happens when I create a new airplane model.

When TX does not create a new model airplane, the TX returns to the initial menu showing a voltage of approximately 5v until reaching the battery voltage.

It appears to be eeprom error.

Is this happening only after you tried er9xV2 (mbtx)?
What you are seeing is a watchdog reboot.

Hi Mike ...


I use r821(r820 in radio), ER9x, M2561, I have two radios with the same setup. This one has this problem.

He says that he has 2 radios with the exactly same setup, but one of them has the problem..

I already tested two microcontrollers (m2561). With the M64 it worked.
FUSES: Baixo=de Alto=d1 Ext=fc, Argument used -B 1000

I've posted a specific test version (prov 822), for you to try please (on the er9x test versions thread). This re-triggers the watchdog more often when creating a new model.

Hello, today I changed the microcontroller to one that I'm sure is working. When I saved a new model, the 47uf capacitor after the 7805L burned (short circuit), also burned regulator 7805L and 6206A.

I changed the capacitor and regulators and TX stopped rebooting.

I understood nothing !!!
Everything working so far normally.

I'm not sure why the components burned, it can be an accident (very difficult).

So I soldered one of the microcontrollers that rebooted on a working board, and then the board that was working is now rebooting while saving the new model.

Conclusion.

I think the 3 microcontrollers I bought on aliexpress, were defective. But it may be that the power supply circuit is a suspect.

Tks !!!
Marco.

To me it looks like there might have been a stray blob of solder that shorted something..

But good that is working.. Well done
Parabéns

The watchdog timing does vary from one processor to another. It is possible the CPU(s) that don't work have a watchdog that is running fast, so are causing a reboot when others don't. Have you tried the special test version I posted on the board that is rebooting?

This all exhausted me enough for today ..... I will try later the version prov 822.
I have to replace the components of the other mother board, which ended without them.
Soon I will post the results with the prov822 version.

Tks Mike and João

Is this the version?

No, the one I posted today "er9x-2561K1.zip", marked for your testing!
