Hi @st Team,
We had observed some unknown behaviour with respect to flash.
MCU => STM32U073CC.
Tools => STM32Cube Programmer
We need to write this mentioned value @last page of flash @address = 0x0803F800.
After doing multiple connect/disconnect, The mentioned value got disappeared abruptly.
Please refer the below after disappeared.
Note - the probability of this issue occurance is much higher.
Please help us to diagnose this issue.
Best regards,
Shubham M.

Hi,
i tried on a F303 , U0xx dont have here. (+ V 2.19.0 , stlink FW V2J46S7 )
But with 32b access....no problem (nothing "disappeared" ) after many conn/disconn.
So just try : with standard 32b access and mode : hot plug , software reset ;

I tried on the Nucleo-U083RC,
MCU => STM32U083RC.
Tools => STM32Cube Programmer
it is OK after reset, the programed value is there, not disappeared.
