Hello everyone ,i have some problem with Jovy System RE8500 BGA Rework station the pcb board from rework mashin use c8051f340 MCU for controlling processes, unfortunately the mcu is broken (short circuit caused by soldering iron) ,i put new one (soldered) in order to provide original jovy systems-firmware i need to flash usb bootloder to mcu or to activate usb port in the mcu ,so i ask for clarification which file i need to flash ?there are many file in folder as200 here? or maybe the usb bootloader is integrated in firmware i dont know ? i have also Silab Debug adapter and original Jovy Systems firmware, the LCD shows only two rows of blocks but no usb connection to pc . thank you

What kind of firmware do you have? A .jfw file like this: http://nightforce.free.fr/upload/RE-8500%20FW%20Ver.1.10.rar ?
.jfw looks like some "binarized hex" (a binary with address table header), it's start address seems to be 0x1400 - that matches the AN200 memory map, but also means that it doesn't include the bootloader itself.
The correct C8051F340 bootloader file from AN200 is USB_BL_F34X_64K.hex, but Jovi's version can have some modifications making it incompatible. Try and see.

Update: studying JovyPCSuite.exe in dotPeek shows that Jovi's bootloader protocol doesn't match AN200

However, I've built a combined image consisting of AN200 BL, Jovi 1.10 APP (from update file) and valid BL signature block. Could work (if the APP doesn't check the BL).

Silab flash utility seems to have driver problem ,do you know solution for that problem?

inquisitor · « **Reply #5 on:** May 20, 2020, 03:46:59 pm »

did you see in the firmware update guide? (attachment) the mcu bootloader use same usbxpress windows driver from silab? if software pc suite recognize usb connected device the firmware update can be done buy using pc suite or what do you mean?

abyrvalg · « **Reply #6 on:** May 20, 2020, 05:05:36 pm »

Jovy uses Silabs driver to talk to the bootloader, but the commands they are sending are different from AN200 protocol. Jovy PC Suite will detect the USB device, but will be unable to communicate with it.

Pictures of working mashin

Great! Glad to hear that

There is one limitation: since the bootloader is different, the firmware update function will not work (PC update tool will not detect the machine). But it looks like there are no more updates anyway.

Hi abyrvalg ,i use one working jovy pc suite ,two years ago when i bought the mashine i use olly dbg to crack the software ,because i did not get response from jovy systems to get license ,now i need the software on my new pc ,but i dont rember how i dou ? any solution for the problem ,or i need to clone windows?

Hello. I have a similar station from jovySystem Jetronix Eco with a damaged processor after switching to usb. Will someone explain how to upload fimware to a new processor?

abyrvalg · « **Reply #16 on:** August 19, 2020, 06:30:23 am »

I need an original firmware package for that model to construct a full image. Can’t find it.
Edit: found it here: https://www.hotair.pl/oprogramowaniejovy

abyrvalg · « **Reply #17 on:** August 19, 2020, 11:30:10 am »

Try flashing the attached file. You need to use a "Silabs debug adapter" and the corresponding software to do that.
Not sure if Jetronix has the same MCU as RE-8500 (C8051F340). Tell me if it is different and I'll make another image.

okraglaczek · « **Reply #18 on:** August 19, 2020, 09:32:41 pm »

Jetronix eco has the same C8051F340 MCU.
I am already ordering from the DEBUGADPTR1-USB online store
Thank you for your help, I will write if it worked

okraglaczek · « **Reply #19 on:** October 18, 2020, 03:43:21 pm »

I tried to upload the dump but I think I'm doing something wrong because it doesn't work! do I have to select some options in the program?

okraglaczek · « **Reply #20 on:** October 18, 2020, 04:43:25 pm »

error

abyrvalg · « **Reply #21 on:** October 19, 2020, 10:15:38 pm »

Does the station’s interface (display, manual controls) show any signs of life after hex flashing?

vik_g · « **Reply #22 on:** December 05, 2020, 11:36:48 am »

The program must be run as administrator.

Hello,
I recently bought an Jovy RE-8500 station (almost new) for my workshop. I like the rework station. It's a shame that the manufacturer no longer exists.
The station has a couple of minor defects. The laser does not work, the vacuum tweezers are weak. It's all fixable.
The reason I am writing to you is. Is it possible to read the firmware from the C8051A340 Controller?
From the memory of 24C64WP, I think I can read it. But the C8051 is problematic.
If I have already opened the control box, then I think to make a backup copy in advance in case you have to repair it.

I have Silicon Labs USB Debug Adapter and Silicon Labs for C8051xxxx, but I can not find the read function.
PCB Rev.: 2.03
Maybe someone has already done this? Or is there already a dump so that I do not risk in vain?
And what about activating license for a computer control software? Can I get around it somehow?
Regards
Tudor

there was still a damaged display. after replacement, it displays well for a few seconds, then the image is distorted.
