Hi builders,

i am trying to update my Maytech 4.12´s Vesc with the VESCTool. The current firmware is 2.18 if i connect the VESC the software says firmware is too old but boot-loader is detected please update the firmware. If i do this, it does it´s thing and i wait the appropriate time, but after reconnecting the VESC it still says old firmware and after checking with the old BLDC tool it says still 2.18 firmware. Does anyone know´s what i am doing wrong? Help please. And sorry yes, i used the search bar but could not find anything.

Thanks!!

SOLUTION

The solution was, that the Maytech VESC´S came without the bootloader installed. The Vesc Tool gives you false positives regarding a installed bootloader. Installing the bootloader is so easy now, you can just do it via USB cable.

Anyways thanks to everyone trying to help me!!

How did you go about updating the firmware? Did it give you the screen where it allows you to choose hw version 4.10/4.12 and then you could click on the firmware version?

Thanks for your help!

Yes i choose 4.10 4.11 4.12 and then the bin file, after that the green bar advances to 100% and the VESC disconnects, then i wait and nothing happens. To reconnect the VESC i have to power off and on again.

That’s weird because I’m pretty sure the vesc should disconnect and automatically reconnect after a couple seconds. Try a different usb cable and see it that changes anything otherwise I think you should switch to ackmaniacs extended bldc tool and use his firmware or go back to the original bldc tool with 2.18 fw

Thank´s man!! I tried already two cables… will try further! The strange thing is that the tool doesn´t show VESC COM 05, it only shows COM 05. I opened the tool as administrator, shut off the virus protection all to no avail. Thanks anyways the motors are spinning with the old firmware too, so not a big deal!
