I bought a BetaFPV 95X (V2 I think) with Caddx Vista (used), and I’m unable to connect to beta flight. I’m pretty sure I screwed something up when I tried to flash the firmware. I’m 100% stuck, tried the reboot sequence with the boot button, etc. Itll occasionally connect, but then quickly disconnects. Would I be better off buying a new FC and starting over? I really hate to have wasted $$$ on this thing if I can’t get it up and running. Really appreciate any help!! Otherwise: If anyone’s interested in buying this thing with a naked GoPro I’m happy to sell it cheap • Posts: 68 Threads: 16 Likes Received: 28 in 18 posts Likes Given: 7 Joined: May 2023 Reputation: 1 Maybe a dumb observation on my part, but are you 100% sure your usb cable is not just a charging cable? I made that mistake. Changed cables and it works like it should My ability to remember song lyrics from the ‘60s far exceeds my my ability to remember why I walked into the kitchen just now • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 26-Sep-2023, 05:16 PM (This post was last modified: 26-Sep-2023, 07:47 PM by voodoo614.) Try reflashing in DFU mode. You cannot really brick an FC, so you don't need to buy new FC. Hold he boot button then plug in the USB. Once you see that BF recognized that the FC is in DFU mode, you go ahead a flash again. If BF does not see the FC in DFU mode, you might need to load the Zadig driver. You can tell if you need to load the driver by booting the FC in to DFU mode. Then go to the device manager. If you see a device with an yellow ! mark, you do not have the driver. If you are on a Mac, the driver should already be there. https://zadig.akeo.ie/ • Posts: 10 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 0 Joined: Sep 2023 Reputation: 0 Thanks for the help, I’ll try these tonight when I get home. Does it make any sense that BF only recognizes the FC when the battery isn’t plugged in? Just the usb… • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 (26-Sep-2023, 07:30 PM)Goforbroke001 Wrote: Thanks for the help, I’ll try these tonight when I get home.

Not allowing the 5V from the USB to power the FC. There is not need to reflash if you can connect to FC with lipo power. You have a few choices. 1. Live with the FC. You need to power from lipo everytime you make changes. 2. Try to repair the FC if you are into microsoldering. (personally this is my choice, but is not for most people) 3. Buy a new FC (probably what most people would do) • Posts: 1,767 Threads: 61 Likes Received: 1,033 in 746 posts Likes Given: 97 Joined: Jan 2023 Reputation: 53 For some of the older FCs, I seem to recall it shared a UART between MSP and a peripheral. If that was the case then having the peripheral connect/powered up would prevent connecting to the FC via USB. • Posts: 10 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 0 Joined: Sep 2023 Reputation: 0 Update: BF identifies “COM4 - Betaflight STM32F405” and also the board “OMNIBUSF4SD - version 4.4.2 - June 2023” However, when I hit “connect” it will say “serial port successfully opened,” but then nothing happens, stays on the initial screen, then says “serial port successfully closed.” Without me doing anything, after 5-10seconds. Then it’ll say “Failed to open serial port” the next half dozen attempts to connect to BF • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 Go to Device manager.

Can you post what pops up? • Posts: 10 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 0 Joined: Sep 2023 Reputation: 0 I think I’m just going to buy a new stack and start over, it should be less hassle and stress than trouble shooting this electronic communication black-hole. Everything happens for a reason as they say, I’ve been interested from the sidelines in learning electronics soldering, so I think this is a good time for me to learn. I have some slight experience in soldering wires, but this will be next-level, so I’m excited to try. Any advice on equipment or techniques? My current soldering equipment isn’t really meant for micro-electronics. Any advice would be much appreciated! • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 If you have a driver issue, then you will have the same issue with a new FC. • Posts: 10 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 0 Joined: Sep 2023 Reputation: 0 (28-Sep-2023, 03:49 AM)voodoo614 Wrote: Go to Device manager.

Your new stack should connect to BFC without issue. If you are still having problem on the new FC, then we can say something is wrong with your computer driver or the cable. Since you don't have a working FC that connects to BFC, it is hard to right out the factor that causing your current issue. If you still want to try to get your current FC working, the last thing you can try is reloading the STM driver. And make sure you have an USB cable capable of data transfer and not just a charge cable. I honestly don't think is your cable because BFC was able read the firmware target. To reinstall the driver, go to the website below and download the driver. Run the exe file to load the firmware on your computer https://www.st.com/en/development-tools/...32102.html Then follow the step as I outlined below. https://intofpv.com/t-com-port-issue-wit...#pid119646 • |
