I want to programm a STM32L471VE with the Flash Loader Demo. The Flash Loader Demo only programms till address 0840000. If I try to erase only page 128 (0x8040000 till 0x8407ff) erase fails. I tried Cube programmer but cannot connect via the Uart.

Do both tools not support the STM32L471VE ?

Flash Loader Demonstrator is old an deprecated.

Used STM3 Cube Probably via UART on other L4, not tried your model.

Perhaps try some of the open source alternatives, or your own implementation of the protocol.
