Ive recently acquired a quattro where the last owner had tried to upgrade the firmware but failed and could not recover it.Im new to this but upto now i have managed to connect via ve config and also ve flash. On both software’s the unit is identifying as a multiplus 2 48v where as it is a quattro 24v.I gather this is where the previous owner has encountered the issues but i can not seem to rewrite it with the correct firmware. Victron connect tries then fails and ve flash comes up with a screen stating it is the wrong firmware for the product however it clearly shows on all identifying stickers the board is indeed a 24\3000\70.ve config is showing the item as a multiplus 48v however it is a quattro.I have read an article somewhere where someone as managed to write to a chip by plugging into an identical machine and then switching the connection before the write.Im struggling to understand how the wrong firmware has been wrote to the board initially but I’m sure however it was i should be able to do the same to correct the issue.any advice much appreciated thanks mark
It sounds like you need to take this device to a local repair center for assessment.
If the tools that are available to end-users don’t work - veflash is typically a last gasp effort - then there is little else open to you.
Maybe provide some pics, screenshots and specifics about versions being used.
It isn’t possible to write incorrect firmware to a device. Updates can fail, but are typically recoverable.
Are you sure this isn’t a second-hand Frankenstein model someone cobbled together for resale?
Pop the serial number into the support URL, it should confirm what it is supposed to be.
Images attached im pretty sure its all the correct hardware serial numbers match etc
Looks that way, but a 2012 model so, long out of warranty and production.
Your only means to update that device from the original version would be via veflash iirc.
You may have bought yourself a lemon.
I don’t recall similar issues before. Maybe someone else has.
What does it show if you go in VE.config to Target → Show software version ?
It showing if i remember correctly 2669501 firmware however the correct for 48v multiplus
Its even showing the correct serial number however the board clearly shows it as 24/3000 Quattro case shows the same do you know where the sofware reads this information from i would of thought it was from the board thay marked Quattro? Tia
The SN doesn’t matter here, many years ago you needed to enter the SN manually during the FW update and that’s what the previous owner did. You can see that because some of the letters are lower case.
Later that was done in the factory and there the SN has all upper case letters.
He could have entered everything there.
I don’t think there is an easy way for you to get the correct FW installed because the device is out of warranty for many years.
What FW is currently installed?
Does the device work?
Multi plus firmware is installed 2699 device wont work needs 2641 installing tia
You could try to install the last 2699 FW but I don’t think that will work.
You will need a new control PCB with the correct FW installed but I think that is not available as a spare part for such an old device.
I dont think the latest 2699 will work either becuase voltage will allways be wrong. i camt understand how he has managed to get 2699 on there but he has so there clearly mist be a way to get 2641 back.im wondering if there is a way of stopping ve flash from doing an id check before writing or if there is a way of altering the 2641 firmware file to look like a 2699 tia
Have you amy idea what the jumper pins are for located under the chip ?
I’m pretty sure there is no way for you as an enduser and you won’t get any official support for a 14 years old device.
That’s described in the manual that can be downloaded.
Ok i will take a look thank you
Sorry I thought you meant the DIP switches.
I guess that pins are for the factory or diagnostic by the developers.
You won’t find any information about that.
They are the ICSP pins for the microcontroller - power, programming voltage/reset, serial clock/data.
You can program the micro through there, but you need the unencrypted binary image - which nobody will give you.
No problem thanks anyway
