Read the firmware does not work, it is worth reading protection. That is, 100% drone can be put on the shelf or in the trash
After self-torture, I still-pulled the firmware from the flight controller. True, the gyroscope does not work for me, but it seems that it itself broke, well, or the cable is damaged.
Therefore, if everything is fine with you - accomplish your goal, and if someone gives or sells a gyroscope card, I will be very grateful. Since they are not sold separately, I don’t want to buy another board with a gyroscope at all. And so there are already 2 boards.
It was not possible to flash through MP, flashing through the ST Link V2 programmer, via J-Flash Lite interface SWD

can you tell me in a simple way how to flash the firmware with arduino … or what program and hardware you used …thank you
One thing that I really like of this copter is that it uses only one 802.11ac link for all communication purposes: RC, FPV video and telemetry. I would like to have the same thing on my DIY copters instead of 433MHz for telemetry + 2.4GHz for RC + 5.8GHz for video.
It could be an interesting DIY project to replicate the same comms stuff of this c-fly dream for DIY copters.

Hi. Has anyone figured out how to flash the c-fly the easy way? I am interested in the subject since I have a c-fly and was hoping to update the firmware.

Hello, I also would be interested, because I have a c-fly who dont boot up again. But I think the answer for the easy way is already given in post 19, meaning there is no real “easy way”
I’ve ordered one twice through aliexpress and each time the order hasn’t arrived. Do you have a good link?
I didn’t try but I see that banggood and gearbest sell the c-fly and jjrc x9
Thanks: just a bit wary after two failed attempts. I was hoping someone could share a proven place to purchase.
Regards,
James
4th attempt, but it arrived. (Gearbest got through). I can have a look at the innards now

Hi james is one year that my X9 is stuck… now i have the ST-link v2 , please can you tell me the procedure to connect the X9 MB, the program to use the ST-Link… Thanks
I didn’t use st-link, just USB.
Uploading firmware “works”, but haven’t managed to get a running firmware build. Spent a fair bit of time trying to reverse engineer/guess a hwdef for it, but no success yet. I won’t be able to look at it for at least another two weeks as I’m traveling.
I’ve been playing a bit with the JJRC X9 here. I built and loaded ArduPilot master on it successfully, but haven’t yet got it to find the baro or IMU.
I added some code to put patterns of pulses on the likely pins between the main MCU and the IMU connector then probed the IMU connector with my Saleae. I didn’t find the pins yet, which makes me wonder if the IMU may be connected to the F103 (that would be quite strange, but possible).
I’ll expand my pin probe list to try and find any pins on the IMU connector.
I’ve also added a script to make it easy to create an apj firmware file from the bin files that others have added above:
Using that I tried loading those firmwares, and while they load and boot none of them bring up the IMU. So I think there is an IMU difference between the JJRC and the C-Dream.
Cheers, Tridge

I now have IMU and baro working. It is a DPS280 baro and ICM20689 IMU, both on SPI2.
I’ve started a branch here with a hwdef.dat:
next step is IMU orientation, then start on motors, mag etc

I’ve found a mag (an IST8310 on I2C) and GPS (u-blox M8)
I’ve updated the branch above
