content: 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

content: 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.

content: Update: studying JovyPCSuite.exe in dotPeek shows that Jovi's bootloader protocol doesn't match AN200However, 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).

content: 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.

content: Great! Glad to hear thatThere 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.

content: 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.

content: 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.: 2.03Maybe 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?RegardsTudor

content: Thanks for the answer.I have tried all versions from this site.Also with changed the IP address to French. Everything exactly the program is launched as not licensed.I even received a license file from the sellers archives with the correct serial number. Everything exactly the program is launched as not licensed. I think that he did not send me a fake.Why is this so?Please help me.

content: You can chek the elstien T-SHT 600 with the simple ohmmeter. The heat spiral must have several ohms. Approximately until 10 Ohm. If the resistance is very high, then you must check the connecting the spiral with a further wire.

content: After using a firmware with Silabs bootloader there is a problem with connection using Jovy PC Suite. Problem is caused by unoriginal bootloader, app try to get serial number from bootloader area and convert it to number what trows exception because data is rubbish, not a serial number.So, I patched original .exe to use file sn.cfg as a external source of serial number. Without this file app will use hardcoded serial number for RE-8500 rev 1 with 5 TC. If you want to use with 3 TC version(serial number above JV85114013) or RE-7500 you should provide valid SN in config file. Licence files are not longer needed.
