Answer 1

Hello,

difficult to say what is going wrong... Just a few things that you can try:

• Please make sure to have a good power supply connected - I got similar problems during the flashing when I just used power via PC.
• You can try to use the STM32CubeProgrammer CLI under Windows.

Does this help?

Best regards,

Manfred.

Many months later I was again fighting with the same issue - it was the poor power supply.

So if someone get "Error: Unable to reconnect the target device" when trying to download the image on SDCard via STM32CubeProgrammer (IDE or CLI), please try again with a really good power supply.

Answer 2

I encountered the same problem and was helped both by online.support@st.com and internet searches. The download process requires a re-enumeration of the usb port ("gadget" gets added to the name string part way through the download) and this is not supported by default in virtual box. You have to download the "Virtual Box Extension Pack" for your version of Virtual box to get the re-enumeration support. A good "how to" for that install can be found here:

Note that even after you install this pack the download will still fail the first time, but it does seem to fix the problem.

Good Luck!
