Which tab is selected doesn't matter.

Down might help.

Would be proper SD contents missing.

No, not possible, it fluctuates too much with noise to make any sense. You can set a value to 2 decimal in a logical switch to trigger an action though.

Mode and channel order are completely different things, nothing says that when you fly mode 2 throttle should be 3, channel order is manufacturer preference. So move things around in the mixer the way you want them, and set the default channel order in settings so that new models get created with th...

Counterfeit cards.

You don't need an SD card for FrSky OS

No.

Sbus is consistent of 2 frames, if one is good and secon is bad, we have bad Sbus. It can happend even on solid line. Now if comes bad frame we drop it and use prevous frame what was good. So we reconstruct good sbus signal. That isn't exactly correct, when people use D16 with only 8 channels they ...

Well, you have make sensor from Tadango what reads SBUS, but SBUS is not real reading of the line quality, do you know how this really works? Well if a packet was lost and there is no new data then the SBUS frame lost bit should be set, that's the whole point of it. If it is not then it is "cheatin...

Yes, you need to select the "internalmulti" firmware option.

It's in the list on the FrSky page with a direct link...

Why post this? The whole point of linking to the github page is to have up to date information if it changes.

Might be easier to understand if you described what you see / expect to see when.

SD card access needs radio in bootloader, can't do that when off...

The default splash is built into the firmware, you can't "lose" it...

You will not be able to control updated FrSky receivers with a multiprotocol module anymore, at least not until someone reverses/reimplements the new protocol.

Nothing is supposed to change outside of the actual RF transmission.

No, once the bootloader is on flahsing the firmware is done using the normal TX/RX pads, that's the bootloader's job.

The radio uses the card for everything so if it works the card and reader are OK. Probably bad or charge-only USB cable.

2.3.5 is now released with the fix for this.

Correct.

You're looking at the wrong column then, the first one is the switch to enable the function.

They are probably disabled in hardware settings.

There's a bug in all 2.3 versions with that combination. It was first reported yesterday and is being worked on.

SD card present, log recording, trainer cable connected in master mode

You might need a pull-up resistor from the receiver supply to the PPM line then, maybe start with 10k.

The zip in the post you quoted has a firmware that FrSky posted at one point very long ago. Not sure if it has changed afterwards.
