PA01 - system freezes when operating buttons without unplugging the USB cable in SD card mode

[FlyskySoft]

Is there an existing issue for this problem?

• I have searched the existing issues

What part of EdgeTX is the focus of this bug?

Transmitter firmware

Current Behavior

In SD card mode, long-pressing the power button triggers a confirmation screen for shutdown. However, regardless of the option selected on this screen, the interface becomes unresponsive and freezes.

Expected Behavior

Here are two reference solutions provided:

Solution 1: Display a pop-up window indicating that shutdown is prohibited, and return to the SD card mode interface after a three-second prompt.

Solution 2: Determine if there is no data transmission before allowing shutdown, and prompt for USB insertion confirmation upon shutdown attempt. Otherwise, display a pop-up window indicating that shutdown is prohibited, and return to the SD card mode interface after a three-second prompt.

Steps To Reproduce

1.Long-press the power button to turn on PA01 and enter the main interface.
2.Connect the data cable and select [USB Storage (SD)].
3.After entering SD card mode, long-press the power button.
4.After selecting [RTN] or [ENTER] on the shutdown prompt screen, the interface freezes.

I suspect there are some issues with the USB SD on the PA01.
While testing this I also found USB SD issues #6949 and #6950.

The correct behaviour is:

• press RTN key or RTN button, dialog closes and returns to USB SD view
• select and press [ENTER] button on screen and radio powers off

All other color radios I have tested behave correctly.

Also the exact same code is used to handle the case when the radio is connected to a receiver while powering off. The PA01 behaves correctly in this case (tested with internal module set to ELRS).

I don't know if this has any bearing, but in trying to see any difference between them, out of the PL18, ST16, T15, TX15 and PA01... this is the only one that shows RTN instead of Cancel (and freezes).

That's due to version - 2.11 vs 2.12/3.0.

So only 2.11 branch has this problem? and Not 2.12 or 3.0?

[pfeerick]

No, it is relevant to 2.11.3 onwards. 2.12 onwards just has different button text, but exhibits the same issue. What I find curious is that Cancel / [ RTN ] does not register (and the radio will power down if you disconnect the USB after having selected that option). This is still confined to the PA01 though.

Some user reported this problem to me as well.
