Flysky FSI6X Open Tx Firmware Installation via DFU Mode

#Flysky #FSI6X #OpenTX
In this video we take a look at how to install Open Tx firmware on the Flysky FSI6X Radio transmitter via the DFU mode so that you can avoid using the st link usb programmer.

00:00 Intro
01:11 Bridge R53 Pad
03:10 Solder R53 Pad
03:51 Test DFU Mode
04:40 STM32 Cube Programmer
06:20 Connect Radio To Pc
07:40 Backup Original Firmware
08:15 Installing Open Tx
08:49 Remove R53 Bridge
09:15 Test New Firmware
10:01 Open Tx DFU Mode
10:49 End

Thanks for watching!

You dont have to solder wires to the R53 pads, I've used a pair of tweezers like the ones you use to point to the pads and it worked like a charm. You only need the pads bridge the moment you power on the radio, you cand remove the bridge after and the radio will stay in DFU mode

Hello @Rakish Rc I'm trying to put the radio in DFU mode but windows recognizes the usb as a malfunctioning device, can anyone help?

[luisfilipe]

Great option, but once again i have to ask..will it work the same for the i6 radio? Just jumping the r53 pads?? Maybe not...considering that the main board is different🤔

[Kartikt]

I had do same..but now my fsi6x is garbage for me.
After installing opentx.every time when I on the switch.shows switch warning ABCD & throttel warning..then when i fix it all switch and throttle position.its hanged after last action.then restart with fix all switch and throttle.only show White screen..also instal old firmware but tx not responding still in dfu mode like.please help

So I updated to Ver1.6..0 using STLink V2 & four wires - worked Great - rebooted Transmitter and noticed wrong language selected - powered Transmitter off and installed serial cable & pushed both horizontal trims to center to set to DFU mode - now unable to reprogram using STMCubeProggramer (no connection to usb - windows sees device as DRPm32DFUISPMODE (NO DRIVER) & NO COM. - ANY SUGGESTIONS ?

[MarkusPeikert]

thank you for your good structured video.
unfortunately i now have the problem that my chip is read protected. do you think it will be better when i buy st-link?

Hi Rakish, I am interested in your method to install opentx on flysky radio because I would like to use a headtracker with mine. As I saw in your video dedicated to the use of headtrackers, I have to install open tx on my flysky. However, I have an fs-i6. I saw in one of the comments below that there is another firmware for fs-i6 but is it opentx too? And will I be able to use an headtracker with this other firmware? Or should I rather buy an fs-i6X? Thanks

Helping Hello, is there any other place to connect to the broken left pin in the R53 jumper?

[readlee]

If you do not want to solder the R53 pins and you have standard FS-i6X firmware, you can enter DFU mode via the following process. Power off the radio, push and hold the left vertical trim to the right and the horizontal trim down.. While holding them, power on the radio. The LCD will stay blank and you are in DFU mode.

That said, whether I enter DFU mode via this the trims or by soldering the pins, my radio isn't read as any STM32 device, it is still read as a flysky radio controller?? I'm going to try the ST-Link v2 adaptor instead.

Can you make a video flashing the original flysky firmware to the flysky f6X transmitter?

[zio_cuy]

Its a great info, but i have a question before i installed open tx firmware,
1. Is protocol stil afhds and afhds2?
2.Can we change the power output
3, is there a timer in it?
4. Can we back using flysky original firmware?
Thx a lot...

Hi rakesh bro.
Did we can flash from i6x firmware directly to openi6x 1.3 with this method ?

[lokaero]

Hi rakish. im having a problem here. when i was updating unfortunately my usb disconnected. now my tx is dead. not turning on can u give me soultion?

[leivinreec.dolenzo]

thank you for this informative viode my friend just flash on the 1.4.0 version on my transmitter. I just notice that the higher version you download it wont work due to increase of memory usage of the new update file so my transmitter work or only accept the 1.4.0 version.

Hi, I did everything according to the instructions, but when connected to the computer, no USB devices appear at all. In my case, only ST-LINK will help? Maybe you have faced such a problem? - Windows 11

[ruanvandermerwe]

I followed your steps exactly and everything seems to work, however when I press "download" the STM32 program just loads and loads. I have tried previous versions of the Openi6X but all just keeps loading....Any suggestions?

[sirhcw]

In device manager its labeled as other devices- AMP32 DFU ISP Mode. What is wrong and what do i do to fix it

[AmysuNono]

UPDATE: I'm upgrading from original FW to Openi6x v1.11.1 by following this tutorial BUT the TX seems like it is bricked and does not display anything. If you have the same issue, you can try to do full ERASE using STM32 Cube Programmer and then try to re-flash following this tutorial. I realize that the output log in this video did show "ERASING SECTOR ..." which I suddenly thought that why his step does involve erasing sector when by default, STM32 Cube Programmer will not erase the chip and may show "Sector not found".

If you have stored Models in Transmitter - do they stay or you have to re-program them?

[Rooonga]

Windows isn't seeing my controller. I'm using a cable that has a kind of audio jack in it. Is this the wrong lead? I'm hoping it's an easy fix with a new USB data cable. Any advice would be great thank you
