NO => you need to adapt the bootloaders (TF-A and U-Boot) for your 
custom board, in particular the DDR and the USB part

Here it is the first USB enumeration in ROM-Code

=> all is OK, the STM32MP15 is detected with ||

# |DeviceID :0x0500|
||


Then TF-A is loaded in internal RAM and executed....

STM32CubeProgrammer reconnection failed after START request

I assumed reenumeration Failed => TF-A is NOT running here !


Here you need to check the TF-A output on console uart to check the 
reported errors....

As the TF-A is not running correctly here, the USB stack don't running 
in device

the USB enumeration failed, for this second USB connect request

=> product can't be detected = |"ProductID :"|

|
|

|by default the STM32CubeProgrammer assume STM32 MCU|

|=> the 'tsv' opteion is not supported, only supported for STM32 MPU 
(STM32MP15x STM32MP13x)
