  • How to connect JTAG and RS232 port

    To upload CFE you can use service tool BS3 for iBox II+/III
    Select Flash (EEPROM): Winbond W25Q32BV
    BTW: I don't use wire 3.3V because JTAG is powered by USB port.

      BrodcamStudio 3 for JTAG recovery
      You can't use RS232 for recovery, but you can check CFE boot log.

        For those who do not have a serial port, take a cable PL2303 : http://www.aliexpress.com/item/Free-...945292071.html
        The driver can be found here : http://www.prolific.com.tw/us/showpr...id=225&pcid=41

        I use this cable to all types of box.

            CFE in ZS S2 is resistant for damages, you should try to load well tested image like OpenATV or try to connect RS232 console to check the bootlog.

              I have had a power failure during flashing of my zgemma star h1. when I switch the box on only the red indication led is lighting. the text on display does not appear. flashing with an usb drive does not work anymore. who has experienced this before and knows how to solve it? please help

              I have a cable PL2303. does anyone know which software I need to upload the bootloader (CFE-file)?
              can anyone write a how to about this topic?

              thank you all for your help!

                perhaphs you need to use JTAG

                You can RS 232 to check boot log, but for flash recover/reprogramming you need to have JTAG interface and Broadcom Studio 3

                Guide is for iBox 3, but you can use the same procedure
