oh yes. We are waitinig it too. Our customer needed supported OS.

@JeffZhou Hi, thank you for replay!
It is a pity that this error has surfaced just now.
We are not convinced that such resistor pull-down would be in industrial and stable solution.
So we'll thinking to redo the digital inputs via the I2C expanders.

I have tried to just give power and short-circuit the GPIO16 to the ground, LEDs 16 and 17 turned on.
On GPIO17 0,2V!
on 5 sec booting Omega 2s on GPIO17 voltage changed to 1,16V and led17 has half brightness

Video

@crispyoz does you see this video?
Problem exist may be on some devices not last released and we have it from a box. We order development kit and on him problem exist too.
And we don't know what to do.
We need support. A big party depends on it.

@Lazar-Demin, yes i already try other units of omega as 2s+ and 2S same result(more then 10 units) and of corse all test made in you official firmware without our modification. Only Omega2s/2s+ an Development Kit.
Have you try do this test as show on video?

@Lazar-Demin Hi!
i have try all of this on development board and problem is repeated(Ω-ware: 0.3.2 b244)
So an issue with the Omega itself! visual

seem i found a problem - it's abattery
If we don't se on chip model and return from m41t81s to m41t80 in dts all worked fine RTC and watchdog(but watchodg has only on 81s)

@Lazar-Demin, i have see the error when "m41t80"

[    0.654513] rtc-m41t80 0-0068: Oscillator failure, data is invalid.
[    0.660957] rtc-m41t80 0-0068: hctosys: unable to read the hardware clock

and think that may be not correct becouse mistake in driver

Looked at chip and driver
and changed to "m41t81s"
After that sistem have freeze

@Lazar-Demin Hi! Thanks for you answer!
I made changes on dts
and now have freeze system boot, log is

I have check chipset of RTC its correct and i write it on dts as

            compatible = "st,m41t81s";

How we can resolve this mistake?

We try to add RTC m41t81s
First of all we ensure that RTC is worked fine

i2cset  -y  0  0x68  12 1 b
i2cget -y 0 0x68 3 0x7f

and all is good time is go
We run

make kernel_menuconfig

so we select

CONFIG_RTC_DRV_M41T80=y
CONFIG_RTC_DRV_M41T80_WDT=y
CONFIG_I2C_RALINK=y

and i try add to DTS this section

&i2c0 {
        status = "okay";

        rtc@68 {
                compatible = "st,m41t80";
                reg = <0x68>;
                interrupt-parent = <&UIC0>;
                interrupts = <0x9 0x8>;
        };
};

Then we try add driver as selected in RTC support of our chip m41t81s and watchdog and try build as module.
successfully Make FW without errors.
after install on omega 2s+ we can't find /dev/rtc0 and /dev/watchdog0 in both case.

I don't have another idea what we need to do...

We need help!
May be we can order service request ore something else fore fastest response? it wery important as for us and for you, a large order may depend on it.

Hear the link with like trouble Some GPIO pins does not work with custom image
I has install 0.1.10-b160 FW, then v0.1.9-b159.bin it doesn't help resolve our problems..

@Lazar-Demin we need order dev kit it's take some money and time.
as i can see one men have same problems but on GPIO17-14
May be problem on DTS or bootloader?
schematic is

Now we try check value of GPIO16 and GPIO17, values is 0.
Then we change GPIO17 direction to out and value set to 1.
Check again on the values and see that GPIO16/values changed to 1
After that voltage on chip on GPIO17 is 3.3V on GPIO16 1.9V.

root@Omega-3325:/sys/class/gpio# echo 1 > gpio17/value
root@Omega-3325:/sys/class/gpio# echo 16 > export
root@Omega-3325:/sys/class/gpio# cat gpio16/direction
in
root@Omega-3325:/sys/class/gpio# cat gpio16/value
1
root@Omega-3325:/sys/class/gpio# echo  0 > gpio17/value
root@Omega-3325:/sys/class/gpio# cat  gpio16/value
0

So we think may be that is software problem.
How to check it?

@Lazar-Demin it'a a our custom HW
no problems were identified in the technique
phoned, there were no problems on the ommega2c chip itself

We want to use GPIO16 and GPIO17 for sensor gerkon.
But when GPIO17 state changed to 1 from 0 simultaniusly it has make same changes for GPIO16.
And when i have try to change GPIO16 we reseived same data in GPIO17.
At the same time changes on GPIO15 or GPIO14 workes perfectly.
But only GPIO16 closed and must be HI and same picture when closed GPIO17.

root@Omega-3325:~# gpioctl get 17
Using gpio pin 17.
Pin 17 is LOW
root@Omega-3325:~# gpioctl get 16

root@Omega-3325:~# gpioctl get 17

Somebody can help resolve this?
