STM32CubeProgrammer v2.19.0 USB DFU does not complete the connection

[Hans T]

Hello,
There seems to be a bug in Stm32CubeProgrammer v2.19.0

I connect the STM32F767 with USB1 (DFU).

When I press the CONNECT button, the connection stops at  44 bytes.

the connection is "Not connected"

however, I can now download a program.

Dear @Hans T ,

Can you type in Read Address the RAM address @0x20000000 :  and see/send  the message/log after reading ? 

Thank you. @Aziz BRIGUI  your help is appreciated

Hello.

I can't read the data with USB,

But parallel with the JTAG interface in HOTPLUG mode, I read this:

Hello @Hans T,

Not being able to read SRAM @0x20000000  via USB is expected since the first 16KB are used by bootloader code and are not accessible. You can successfully read SRAM contents starting from @0x20004000.

The "Not connected" not toggling is just a GUI bug and will be fixed in a future release. To work around the button freezing, you can perform a read operation.
