STM32F401 Bootloader Read Memory command failed

I am trying to use the ST Flash loader software for download STM32F401 and there is a problem when the software tries to read the address 0x1FFF7A22 (contained flash size) and 0x1FFF7A10 (unique device ID). It seems that the address is not valid because we receive a NACK from the bootloader when we read these adresses. So it is impossible for us to download the STM32 via UART.

Please, could you confirm that these adresses are correct for STM32F401RC ?
Do you know if there is a new version of STFlashloader fot STM32F401 ?
Do you have encountered some issues on STM32F401 bootloader concerning the read  Memory command ?
Do you have the AN3155 updated for F401 ?

Thank you for your help.
