| TRN:
I recently bought a second hand HMP2020, which is defect. When I switch-on the unit all key leds and also the LCD backlit are on, but that is it. No further response from the unit. I suspect that the application code in the firmware has been corrupted, so I tried to update the firmware to the latest version. When I keep the keys "remote & Current" pressed while switching on the unit, the bootloader program executes and the LCD displays the following text: Firmware update..! Please start update software (BL1.6) Which I presume represents the Bootloader version. I downloaded the latest firmware version 2.72 from the R&S site, and the zip file contains the firmware including the update program. I installed the HO 732 USB / NET adapter in HMP, but when I connect the unit with a USB cable to my PC, I do not get the Normal response:"New Hardware detected" Also when opening the device manager, I cannot see the USB device, and thus cannot update/install the USB driver for the HO732. Subsequently starting the FW update program, the update fails because a connection with the HMP cannot be established. One of the normal tasks of the BL program would be to initiated at least one I/O interface, but for some reason, this does not seem to happen. I do not yet want to open the unit, to see if I can JTAG it, and as such can update the FW, because according to the calibration certificate, this unit is a little bit over 1 year old, and as such is still under warranty. Opening the unit would void this. I have already sent several emails to R&S Portugal with a request to send the unit in for a warranty repair, but so far have received "0" response. But considering that I am a private person and not a company/multi million dollar corporation, I am not going to hold my breath until getting an answer from them. For this reason I am posting this to see if anybody from the forum has any bright ideas ;D Thanks in advance, and any comment are welcome |

Do you know which FW version is currently installed? Older FW did not allow to update via USB, it is noted in release notes (R&S support also mentioned this via email). Look for different adapter for update procedure. FW 2.62 release notes: --- Quote ---The HMP series supports an update of the firmware using the following interfaces: – HO720 dual interface (RS232/USB), only using RS-232 – HO740 GPIB interface Updating the firmware using the dual interface HO730 (Ethernet/USB) is currently not supported. --- End quote --- FW 2.70 (and newer) release notes: --- Quote ---The HMP series supports an update of the firmware using the following interfaces: HO720 dual interface (RS232/USB-CDC) HO73x dual interface (USB/LAN), only using USB-CDC HO740 GPIB interface --- End quote --- |

Hi, thanks that is a good information. I don.t know which FW version is installed, because the instrument is completely unresponsive. Do you know by any chance which date version FW 2.60 was issued? Anyway, I am going to try to source an RS232/USB interface, to see if this will work. |

Do you by any chance have a copy of the 2.62 FW, and if so, could upload it to a sharing site, and provide me the link? Thanks |

Not sure about FW release dates. There is a link for FW 2.62, you can check modification dates (~2015-2018?). |
