General Questions Thread 2025

Either do a screenrecord or move your phone close to the monitor instead of zooming in from all the way back.

Maybe even record how you flash the firmware. We need infos of what is happening

I don’t understand. How else can I download 410/411/412?

Just wanted to leave here

I can’t find them anywhere on the forum.

I think you can download the vesc tool-firmware bundle from here Precompiled VESC Tool Archive

What do you mean by download? You don’t need to download anything other than vesc tool. If you mean upload it to the esc, you literally do exactly what is shown in xsynatic’s image with the arrows. You:

  1. Open vesc tool.
  2. connect the ESC
  3. Click “firmware”
  4. If not already on “included files”, click “included files”. I think you should be there by default.
  5. Click “410 & 411 & 412”
  6. Click “VESC_default.bin” if it’s not already selected, but it probably will be.
  7. Click the upload/write button, which, for whatever reason, has an arrow pointing down.

That is literally all you need to do.

Also, I’ll be kind of surprised if it works at this point. I would expect it to have catastrophically failed already since you’ve tried to run it already with the wrong firmware. You couldn’t do much more to try to break it if you were literally trying. It seems like it hasn’t failed catastrophically yet somehow, though.

The 410/411/412 doesn’t show up in the included firmware tab, no firmware does. I am going to this reinstall Vesc tool and see if that changes anything.

In the firmware tab, try checking the “show non-default firmware” box

Are you on “included files” because in your previous videos, it didn’t look like you were? It’s hard to tell what is going on, though. A single screenshot would have been more useful.

this is no joke.

I’m curious how risky this really is. I would think it would be more runtime failure from things like abs max current set too high or something.

I think the per hw firmware is mostly just hw max for the various limits?
things I wouldn’t expect to blow up on detection?

or are there things like different features enabled in the hw config that might cause somethign to blow up on detection?

but I’m mostly guessing. would be interesting to understand more.

Continuing the discussion from Beginner Question Thread! 2023 Edition:

the focbox unity was the first of those… it had a forked firmware. that was different.

Then @Deodand worked with Vedder and got changes into the upstream code that does indeed treat the two sides of a single mcu dual board as two vescs over can. even tho they aren’t quite.

so yeah it’s the case for single mcu ones.

And for things like hardware values (shunt resistance, adc voltage divider), what is the gate drive circuitry, etc.

If by chance the two ESCs are fairly similarly built it might survive on wrong firmware, but the chances of blowing things up are really high, especially if you don’t know what you are doing. And even if it seems to work at detection things might terribly once actually spinning the motor… Especially at higher speeds and currents

Anybody understand this problem?




Seems to be set to the right settings, but the bms thinks the cells are overvolted even though they clearly are not, they are pretty much dead; so the pack won’t charge.

look at the “protections” section.

What’s that app?

“xioxiangbms”. i feel like it an overkill solar come from the same code base, they’re so similar.

there’s 4 apps. 2 have all the settings access. overkill solar, and xiaoxiangbms. and 2 are like BMS lite apps, and i forget them 'cause i deleted them.

I like it when the @xsynatic is so riled up he’s forcefully helping. :slight_smile:
