Theoretically an SD card could be connected via SPI that is found on the RC input connector on both Revo and Nano (but not on the sparky 2).

But it'll probably be at least a couple of releases before LP devs start considering designing new hardware (might I be wrong...?)

Blackbox would be a nice addition!
The possibility to logg flights and sensors. Whith out the need of oplink.
Maby there already is a "revo" clone that has all funktions. ?
BLHeli or oneshot pass trgogh flashing would be nice to!

Those are both software or firmware changes, not hardware.

Blackbox is cleanflight's modified version of openlog.  There's an open issue requesting support for openlog, https://librepilot.atlassian.net/browse/LP-95   it's waiting for a developer to adopt the issue and program it.

The ESC pass through has also been proposed, https://librepilot.atlassian.net/browse/LP-250 and is waiting for someone to program it.

Ah!
But if I understand it correct. There is need for a memory chip or memory card on the FC boards?

ESC pass through sounds promising. I wish I had the coding skills needed.
Last time I did anything was in the late 80´s  Remember building controllers for LUXOR ABC 80 computers. Old stuff already then.
Some coding Mecman controllers for automation ect.
We had those 5" soft floppydisk as storage for basic programs. I my memory dosent fail. IBM AT 285 was the hottest and newest PC back then..  Ok.. It was a while ago..

No, blackbox is an external board with a micro sd card on it.  No chips on the FC are required, just one of the serial ports.  The board is actually a SparkFun openlog https://www.sparkfun.com/products/13712 cleanflight just modified the SparkFun firmware a little. The board is about 15mm x 20mm.

I started way before the 5 1/4" floppies, the first computer I built in 1975 used an audio cassette for program storage and had a huge amount of ram, 2 thousand bytes.     After that we had 8" floppies followed by single sided single density 5 1/4" floppies that had a huge capacity, 89 thousand bytes.

TY for the info! Learning new stuff every day.
So, not stealing the tread. But, then you remember ZX Spectrum. Atari and Commodore..
Adjusting azimut on tape storage stations..

Hi! I bought a similar controller from Hobbyking, because I want use with Raceflight firmware. I succesfully update the firmware to Raceflight, but the board can't see the receiver neither ppm, neither pwm mode. I tried with other receiver too, without success. I tried the f4 optimized betaflight version without success too... Otherwise the board working, without problems... (certainly I set receiver type on configuration tab)

I'd like return to open or librepilot, but if I tried update, seemingly succesful, but can't connect to GCS, and I hear periodic  "disconnect" tone from PC. On board the blue led nearly constant lighting with little breaks...
I tried update the bootloader, but cannot connect...

What doing wrong?

Thanks for help! Istvan from Hungary

Try DFU recovery:

Edit: you need some soldering for SBL pads

[feket663]

First I thank you for the fast reply. I tried flashing three times, but no luck...

Certainly raceflight working... (without receiver )

here is the batch file's display:

[f5soh]

Raceflight should not be anymore inside your Revo after you flashed entire flash.

Try Upgrade&Erase:
- Disconnect board
- Hit Upgrade&Erase button
- Connect board

- Wait until board remain connected.

"Raceflight should not be anymore inside your Revo after you flashed entire flash."

Certainly I flashed raceflight after I can't connect to librepilot.

I think this board defected, I tried upload+erase option, nothing changed...

Thanks for help, next time I can't buy untested hardware, like this...

What happens with Upgrade&Erase ? Works as expected ?

If yes, try flashing manually the resurrect firmware that boot and format flash memory:

Emergency Rescue Procedure:

Flash and run the resurrection firmware:
- Run the GCS
- Unplug the board from power and USB.
- Go to the firmware tab in the GCS and press the Rescue button.
- Plug the board into USB.
- GCS recognizes the board in a few seconds.
- Press the "Open" button to navigate to and select the correct resurrection firmware opfw file that you downloaded.
- Press the Flash button to write the currently built firmware.
- It will start in a few seconds.  First it will erase, then it will write (flash) the firmware.
- When the flash is done, press the Boot button which will cause the resurrection firmware to run
- Let it run for 30 seconds at least.  On Sparky2, I see blue and green LEDs for 10 seconds, then just green for another 10 seconds, then the board boots normally (LEDs do the normal operation colors).  You might also see just 20 seconds of green followed by normal operation LEDs.

I flashed firmware, what you recommend!
I think, I took a step forward, because the board' leds flashing (green and blue too), but have another problem, I can' connect to GCS... If I pull down connections menu, I can't set the com port, only two options hava, what I attached...

[f5soh]

After you run the resurrect you need to reflash the normal firmware.

- Disconnect board
- Hit Upgrade&Erase button
- Connect board

- Wait until board remain connected.

[feket663]

Half success! The GCS is connecting, but the board still not detected the receiver...

But I can make a film with problem and send to hobbyking...


Thanks for patience and many many help!

Post pictures how you connected the Receiver and the config file you use.
