Can't update firmware
|
I'm trying to install new firmware using DfuSeDemo.
When I start up NanoVNA in DFU mode (with the white screen), and then connect the device to a USB port, Device Manager shows a new Directory is added named "Universal Serial Bus devices", and inside that is a single file, STM32 BOOTLOADER. But I was expecting a file named STM Device in DFU Mode. When I start up DfuSeDemo, and Choose... the dfu file "NanoVNA-H_AA_20191009.dfu", the file gets loaded alright (green bar says "File correctly loaded"), but the Available DFU Devices in the dropdown menu at the top left is still blank. I'd appreciate some help. Right now, I can't make any changes to the firmware. Here's another user with the same problem: /g/nanovna-users/topic/firmware_update_smt_device/34522854?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,20,34522854 |
