EVAL-ADPDUCZ Cannot upgrade the Firmware ( possibly due to driver mis identification)

I have recently purchased the EVAL-ADPDUCZ. However as soon as I attempt to use it it requires a firmware upgrade. Each time I try this is says 'Could not connect to device' device is not in boot mode. We are running Windows 10 fully updated and have tried on three different machines.

However, the device is in boot mode. We know this as we cannot then connect in the normal manner and we get a software driver pop up in device manager telling us that the device is in boot mode.

We think that it may have something to do with the fact that the STM32 Bootloader driver is identifying itself differently to the one shown in the manual as shown below. It is called STM32 BOOTLOADER as opposed to the manual which says it should read 'STM In Device Firmware Upgrade'.

Does anyone have the same issue or know of a fix. At them moment the kit is totally useless. 

Many Thanks,

Dirk

    So, I have had some feedback and I have some questions:

    1. Have you tried with multiple EVAL-ADPDUCZ boards? Or just one? I assume you have multiple but just making sure. If you only tried…

  • Hi, anyone from AD on here ? Shall I just go and get the Maxim part instead seeing as I am $200 of useless development boards out, have a customer waiting for some results and no one seems to answer. ???

    Hi Dirk,

    Unfortunately, you have posted this question to wrong support forum, that's why you're getting a late answer. I am sorry for the delay. 

    Could you please use another computer? We are investigating this issue. Some computers seem to have this issue with BOOTLOADER. You will be able to run the evaluation board after updating the firmware, this is just an issue with BOOTLOADER to update firmware. So, ONLY for updating firmware, please use another computer. I will update you if we find a solution, but we think it is a computer related issue that blocks the firmware update. We are truly sorry for the inconvenience. 

    Also, make sure that you follow the firmware update directions with M4 board (EVAL-ADPDUCZ) correctly. You can check the user guide via "Help" section on Wavetool:

  • Already done this. We tried 4 different laptops, all DELL but different makes and models including a brand new, never before used one. Each one was identical. 

    We are actually very experienced with the STM32F4 processor and we can tell it is in bootloader mode, but the application just cannot seem to use the driver. One thing we heard recently was that a customer of ours found that their latest STM32s had a flag set in the chip that disallowed update via the bootloader. Could this be your problem?

    I have transmitted your problem to our FW/SW development team. I am not a part of that team, so when they find out the issue, I will let you know. I am an optical applications engineer, so when I hear from my team, I will let you know. 

    I actually myself have the same issue, but I was able to update the same EVAL-ADPDUCZs via an old computer. For the same EVAL-ADPDUCZ boards, some computers can update FW, some can't. The  new computers seem to have more issue, that's why I personally suspect Windows updates but I am not sure.

    Honestly, we have never heard the issue you are talking about in the second paragraph. This board is a very established board and used as uC board with wide variety of eval boards. It's actually a fairly old board, it is more than 4 years in production now. We have started to have issues very lately. I am in touch with the team to see if something has changed in SW/FW.
