Updating STM32F373 over USB DFU Fails to Connect

LMorr.3
Senior II

I'm able to connect to my STM32F373 board over a USB virtual port com successfully.  I'm also able to set BOOT0 high via a jumper and boot into the bootloader.  The Linux  'dmesg' command shows:

 

[3552008.377434] usb 3-2: new full-speed USB device number 101 using xhci_hcd
[3552008.526223] usb 3-2: New USB device found, idVendor=0483, idProduct=df11, bcdDevice=22.00
[3552008.526227] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[3552008.526229] usb 3-2: Product: STM32  BOOTLOADER
[3552008.526230] usb 3-2: Manufacturer: STMicroelectronics
[3552008.526231] usb 3-2: SerialNumber: 2077345D2039

 

 However when I run the STM32CubeProgrammer, it does not connect to the STM32F373 or even show it listed in the USB Port dropdown box.  It shows 'No DFU detected'.

I have set the boot jumper on my board and it does seem to be detected as 'STM32 BOOTLOADER' via the 'lsusb' command.

Am I able to use the USB DEVICE in CubeMX as a virtual port com, and then also use it as a USB DFU mode when it's in boot mode?

Any ideas on what I could try?

Best,
