Yes I did update the st16 first and then the H following the video . I’dId not do OTA update in the H but placed sd card in the gimbal and then updated the H . will try later as it is 03h44 and my spousal unit will go tilt and get gimbal lock if she hears the start up tone on the H.

1. I never take off from the roof . I just placed it on roof and then got GPS lock 2. My def of GPS lock is when acquiring goes to READY in green on the ST16 and I can see the gps co-ords 3. Don't know how to look at telemetry files but will google and give it a try 4. I have all files I...

Have left in open space for 20 mins Have done accelerometer calibration. Done compass many times within 30 secs and at the end get solid green light. St 16 - 20 meters from the H Same region ie EU If I put drone on car roof ( ground plane ) get gps lock and co-orders immediately . If I take...

i flew with no problem with the following software Ap v1.29 Gimbal v 1.25 Cam v 3.2.24(A) Did an update from latest download and followed all instructions Ap v1.35 Gimbal v 1.25 Cam v 3.2.34(E) So basically the ap and camera are later version. PROBLEM I can not get GPS LOCK ( green ready...

1. Yes I was talking about the H 2. Held switch in for many more than three seconds but never heard the tones. 3. No it never worked - The boot-loader in the flight module ( small PCB on top of the motor control board ) had become corrupted. You can not program it manually as at the factory...

The only way to get into DFU mode is to tie the boot0 pin on the processor to vdd and boot1 pin to Gnd during power up. Fortunately we have electronic soldering microscopes and fine pitch soldering stations . The processor has a default bootloader that can communicate on USB in DFU mode OR...

To try and close off this matter 1. I had no nefarious motives in spending a lot of time and money trying to " hack" the Typhoon H . Rather I was trying to get a product working on unpacking . I maintain that it is a well designed and conceived solution , at a competitive price point BUT...

I got 2 * boards back from Yuneec Germany today - ( they were very prompt and kept me informed of progress ). The conclusion seems to be - If your bootloader is corrupt the only place the boards can be reprogrammed is at the factory. This is why Yuneec Germany had to replace the boards . The...

I have sent the PCB's back to Yuneec for programming . My conclusions of the month long exercise are -: 1. Dont try and program latest firmware using the USB cable and the Typhoon GUI - This caused the ' bricking ' 2. The processor chip contains firmware that Yuneec don't release and further...

Just for info - wrote to yuneec to try and get the recovery file - no response. 2. All files downloaded from the website are UPDATE files which means the base layer that boots the device has to be loaded and that is what I am looking for i.e. The file/ bootloader that is put into a virgin chip...

The USB cable connecting the PC to the H has 4 pins which end up on the H processor PA9/PA10 = uart1 for programming serial method and the other two wires are routed to PA11/PA12 which allows programming via USB and this requires the DFU utility. When you download the firmware TyphoonH_Ver...

No have not received any flash software from SWM . It seems as if the STM chip comes with a bootloader from the ST factory . This will work with both USB or serial connection depending on which pins are connected . ST have a tool Dfuse which allows you to program the chip ( to access the...

OK - received new STM processor chips and replaced on the flight management board ( the small one on top inside the H ) . Still does not communicate with the GUI on the USB cable between the PC and the Typhoon H . My thinking is as follows - At the factory they load a small program which allows...

Hi John , Tried that and also did not work - My new STM chips arrive on Friday from Mouser so will solder a new one on and hopefully will be able to start from scratch . I am also hoping that Steve Wall Morris may have some instructions . If I get this resolved I will post a detailed youtube...
