Those are apps that you can use to communicate with others.I do not know what TeamSpeak or Discord is.
I'm getting the same issue, hoping it's a PC issue.hello, I am having issues flashing the esc.I have tried wiring it up both ways. I am still not having much luck. The issue I am having is "unable to connect with target". coming from the ST Ulitility program.
I get the solid red light and the green light flashes. One long flash then 8 fast flashes.
Hola !!Dude, thank you so much! I followed your instructions and after changing the serial number, all errors are gone and everything works perfectly. Cheers to everyone who helped I certainly learned a lot during this process.I'd like to add that I have flashed two ESCs with ST-Utility and full dump. The scooter works as intended, however disco lighting has stopped working as mentioned above. The method I used:
Connect ST-Link to ESC
In STUtility press control B and disable readout protection
Open full bin
Press CTRL+P and click program
Go to location 0x1FFFF7E8
Copy first 3 columns of bytes and replace at location 0x0801C1B4
Activate ESC with original ES2/4 serial number
Does everything sound correct here?
EDIT: Turns out it works fine. It seems the lights are faulty on one of mine. I used the ESC on 2 different scooters. Lights work on one, and lights do not work and give a brief error 10 when changing the light colors.
quiero activar las luces en un ninebot snsc alguien me puede explicar donde soldar el st-link que pasos seguir? gracias
Yeah I am in the same boat. I have flashed both the dashboard and the controller board and still getting error 10. This is the ES4 with the extra battery and it had the brain at the top I removed.Hi guys. I have used ST Link and successfully flashed a couple of Dashes and Controller Boards. I've soldered wires directly to the board as well as used a BDM Frame. Now I'm getting "Failed to read memory @ 1FFFFA00!". I have confirmed that my solder joints are good and the wires are in the correct positions. I am using the same method and full dump file but keep getting this error. I even went back to a previous board and tested the ST Link. I thought it was possible the ST Link was bad but it still works fine.
So with this error 10 I can connect with ES Down G but cannot check version so I cannot load the BIN file to flash.
Any suggestions? Thanks in advance.
For the controller, I used a BDM (about $20 from alibaba https://www.aliexpress.com/item/3282232 ... b201603_52)
Followed insructions to flash the dashboard here viewtopic.php?f=6&t=15&start=40
- One thing I encountered is that you really have to scratch the solder on the board quite a bit so your wires can make good contact. Otherwise it'll keep giving errors.
- It's pretty easy to use breadboard wires instead of soldering. https://www.amazon.com/Hyber-Cara-Bread ... s9dHJ1ZQ==. You just connect the ends to the USB ST-LINK and poke the wire through the 3 holes in the dashboard. For that power wire, I just held it in place with clamp. Also this jig seems really useful too https://www.instructables.com/id/Pogo-P ... Connector/
For the controller flashing, Ifollowed diagram on https://imgur.com/a/heG6ETh to connect the USB ST-LINK to the board. 4 wires total. And I used openocd to in MS-DOS command line to run
Followed wielandgeorg's post viewtopic.php?f=6&t=40&start=40 and did the flashing using STM32-LINK app. I think you can do the same using openocd with ("program esc139_fulldump.bin offset 0x8000000"). In STM32-LINK app, I made sure to disable write protection with Control-B and did Unselect All and used Low Power mode. but when I tried to write to address "0x801c1b4", it wouldnt allow me. Something about protection.
Code: Select all
"openocd -f interface/stlink-v2.cfg \ -f target/stm32f1x.cfg \ -c "init; reset halt; stm32f1x unlock 0; reset halt; exit"
Anyways, went ahead and connected everything and device still giving error 10 and there's green on bottom of scooter. Dashboard was a $20 chinese board and control board is original and both I did the flashing.
So far I flashed one dash and two ESCs and it’s still giving me the same error 10. Anyone know how to erase ESC and start over using STUtility. Or did anyone eles beside that one or two people got this to work? I’m flashing a retired rental
can u tell us which diagram did u used and did you use the old one or bought another one. and which scooter did u usedI just wanted to post something I ran into.
I flashed the ESC with the full dump, everything worked fine.
I wanted to changed the dashboard to display mph instead of km so I opened the Ninebot app and connected to my scooter and performed the change.
Everything seemed okay, I then went and flashed a cfw over Bluetooth, everything seemed okay, did a test ride after 20 seconds into the ride the scooter shut off, when I turned it back on I started getting error 42.
Looked up the error code found out it was the external battery, I disconnected it made sure all the screws were tight and reconnected it but kept getting the error 42 - after attempting several things, I decided to take the scooter back apart and re-solder the wires back on to the esc and erase the chip and flash it again.
After putting the scooter back together with the extended battery attached I tested it, all okay again - I been riding it since yesterday few trips been long range, the dashboard is back shown krm. so loaded the ninebot app to change it back to mph.. I disconnected and restarted the scooter, and everything seemed okay...
So today I wanted to test flashing the cfw and see if I get error 42 back, after flashing it I took out to test ride damn it the error 42 started back the very 1st time I touched the break...
So if anyone runs in to the error 42 I would suggest re-flashing your ESC with the full dump again, and delete the NINEBOT app from your phone, so you don't ever connect to your scooter with it. Im pretty sure it's the Ninebot app that triggered the error 42
so now the 3rd time I flashed the ESC but this time don't have the ninebot app, nor am I going to flash cfw to it. If it breaks anytime soon I'll update this posting.
