    I don't own one of these, but happen to have collected some firmware update files. Use at your own risk.

    It's not clear which of 52.29 and 52.31 is the latest/best.

    [ Edit: The following attachments are factory firmware; I never supply patched firmware in .rar form, any my patched firmware always has the word "patched" in the file name. ]

    52.29, dated 23/Jun/2021:

    [Редактировать: Следующие вложения являются заводской прошивкой; Я никогда не поставляю исправленные прошивки в формате .rar, любая моя исправленная прошивка всегда имеет в названии файла слово "пропатченный". ]

    Thanks Coulomb, but the archive cannot be opened. I need a password for the archive SV II 5k  SN 96132112101353 2934-07S2   FW Upgrade_2809_DSP INFINI V II 5KW TWIN 52.31.7z

    Chip for inverter

    1. The manufacturer does not provide firmware
    2. You do not need firmware, the processors in these inverters very rarely fail. Very rarely, and after a thunderstorm, they shorten the 5V power supply. It is very easy to check on the 5V power line.
    3. The inverter turns on, but does not output voltage and reports an error, right?
    4. Probable cause, the power electrical wires at the junction burned out. Look at the photo. It is necessary to crimp with tinned sleeves. The wires are copper, the winding of the transformer is aluminum. Chinese inverter, cheap.

    Привет, мой телефон Wi-Fi не видит ключ luxpower, он использовался один раз при попытке настроить, теперь его нет. Также 10.10.10.1 больше не будет работать. Любая помощь.

    1.Turn on inverter with WiFi dongle
    2. Take any laptop with WiFi, scan the network, connect to the WiFi network with the name of your dongle
    3. See network properties, in network settings, DNS server address
    4. Enter this DNS server address in the browser window and you will be taken to the settings console of your WiFi dongle. You put everything you need there.

    Extracting Axpert firmware using JTAG

    * The commonly available DSP JTAG devices are known as XDS100 compatible. These are convenient because they are common, inexpensive, and work for free with the TI Code Composer Studio software. If you want to use that software with other JTAG devices, you have to pay. Code Composer Studio is a large, complex software development environment, but there are much smaller utilities that can be used to do simple jobs like reading and writing blocks of memory (e.g. firmware). Axpert firmware uses the addresses 3D 8000-3F 7FFF (for the larger firmwares), or 3E 8000-3F 7FFF for the smaller firmwares. The bootloader starts at 3F 8000.

     

    [ Edit: Fixed addresses, added bootloader start addresses ]

    [ Edit: added hex file info. ]

    Thanks for the useful information!
    Question. Is the bootloader address 0x3F8000 correct?
    TMS320F2809 processor.
    Isn't the bootloader in flash memory?
    The Single-access RAM (SARAM) area starts from address 0x3F8000

    Hallo!

    BOOM!!! this processor (STM32F107VCT6) is not read protected!!! I can read good processor and write in new processor data to repair any communication board and display detachable for voltronic inverters! I see any board have jtag connection for this.

    Now can use empty processor without bootloader.

    I have some readed data from STM32F107 and will post soon

    Good news! We are waiting for a read firmware with a bootloader!

    1.The icon in the center of the home screen indicates that the system is Normal operation. If it turns into “comm./F01~F64” ,it means the inverter has communication errors or other errors,the error message will display under this icon(F01-F64 errors,detail error info can be viewed in the System Alarms menu).
