This is my first post on here and I need help. I have been riding for about 3 years, and have done some plug & play DIY builds. However, I am in over my head right now and I don’t know how to fix this.
I have a stock Lacroix Prototipo DSS50+ with the stock dual FocBoxs.
I was TRYING to install a new VX2 Remote, and I figured while I had the enclosure open, I would also update the firmware on the dual FocBoxs.
I have had nothing but problems since I started on what seemed to be a simple update.
Here is where I am at right now: The VESC Tool is reading one of the FocBoxs as “Unity” Hardware with 6.02 Firmware. And the other FocBox I can no longer connect to the VESC Tool because my computer is not recognizing the USB Port anymore.
I’m not sure why the VESC Tool detected Unity Hardware (instead of 410 & 411 & 412) but I trusted the VESC Tool and I uploaded the 6.02 Firmware because that was the only option available. Now nothing works.
Both lights on the FocBoxs are solid blue (with no fault or signal lights lighting up).
How do I get these FocBoxs working again? Is there a simple way to restore the factory settings?
This isn’t for you, it’s for other people reading this thread.
Don’t update firmware just because the tool tells you to!
If it works, leave it alone. Updating microcontroller firmware is not like updating your web browser. If it works, leave it the fuck alone and ignore the messages from the tool.
If you need to update your firmware, you will know, because you will have a reason to do so. Absent the reason, don’t do it.
If this is a FOCBOX 1.6 or 1.7 and you attempt to spin the motor using this firmware, you can permanently damage the hardware. Don’t turn the motor on until this is fixed.
Factory settings are just defaults and won’t make your motors work. But they are a step in the right direction. You’ll still need to do motor detections and set stuff up. Don’t leave the default battery current numbers at 99A. I’m not familiar with the battery or motors in that skate, so maybe someone else can chime in with help on the settings.
This can probably be fixed after you get the other one going, using CANBUS between the two. Or, if that doesn’t work, using an ST-Link tool. Unless it’s broken.
Before you fix this, you need to decide what version of firmware you want to use. I would recommend 5.2 because it’s known to be solid and it doesn’t sound like you need any feature from a newer version.
First, thank you so much for your help!!! It is a great feeling that you are helping me.
After I tried to update the firmware using the “Unity” Hardware and Firmware 6.02, it would not let me spin the motors via the Motor Wizard… So hopefully, there is no permanent damage (keeping fingers crossed).
How do I tell the difference between a FocBox 1.6 and a FocBox 1.7? And is there a big difference between the two FocBox Versions?
At this point, I would be very happy to use Firmware Version 5.02 (or any other version that works).
The question is: How do I get the one FocBox that I can still connect to going again?
When I go to the Firmware Update Page on the VESC Tool, it ready the Hardware as “Unity” and it only gives me one option to update the Firmware. There is no Version 5.02 option.
Is one of my problems that I now how “Unity” Firmware on a FocBox 410 & 411 & 412? Is tthat why nothing is working?
If so, how do I get the VESC Tool to recognize this is 410 & 411 & 412 Hardware and give me the option to upload the correct Firmware?
I would love to use the working VESC to flash the other VESC. How do I do this? (I want to make sure I know exactly what I am doing before I make things even worse than they are).
Also, how do I get the working VESC (the one that still connects to USB) to work again? How do I get the correct Firmware downloaded to the working VESC when the VESC Tool still recognizes it as a “Unity”?
Thank you for the link. I’m hoping I can use the VESC that still connects to USB to “flash” the one that doesn’t work without having to purchase a ST-LINK. But I am not ruling-out any possible solutions.
I’m assuming I get the working VESC’s Firmware updated first. Correct?
If so, how do I manually download the correct FW and manually flash it to the working VESC? (The reason why I am asking is because: The VESC that won’t connect now, used to connect before I tried to manually download the correct FW and flash it. So I think I did it wrong (obviously). That is why the VESC no longer connects). What I did was: I tried just flashing the correct 410 & 411 & 412 Bootloader to the VESC that used to work. Now it doesn’t connect.
As such, I want to make sure I manually download and flash the correct thing this time (because I only have 1 VESC left that will still connect and I don’t want to break that one too).
Yep!! All of the previous VESC Versions are in the “Archive” Tab on the current VESC Tool.
I can see the HW 410 & 411 & 412 and FW 5.02 (This is the one that I want - correct?)
If so, the problem is: One I connect my working VESC to the VESC Tool, the Archive VESC Tab only gives me 1 option for the “Unity” HW. All of the other options disappear. So I cannot just choose “HW 410 & 411 & 412 FW 5.02” and upload it to the VESC.
Yes, that should work, I just have ST-Link, which I also recommend you to get, those clones are cheap. But in the meantime try using your other VESC instead.
