STM32F207 - Error "Device not found in database" but present

[User3546]

With qstlink2, after clicking on 'Connect', i get:

32 Device descriptions loaded.
Searching Device...
ST Link V2 / Nucleo found!
Fetching version...
Changing mode to SWD...
Fetching mode...
Mode: Debug
Fetching status...
Status: Unknown
Fetching MCU Info...
Device not found in database!
Disconnecting...
Disconnected.

The device is not found in the database. But i work on a STM32F207, and in the /usr/share/qstlink2/devices.xml, this device is present:

     <device type="STM32F2xx" coretype="CM3">
      <core_id>0x2ba01477</core_id>
      <chip_id>0x411</chip_id>
      <flash_size_reg>0x1FFF7A22</flash_size_reg>
      <flash_int_reg>0x40023c00</flash_int_reg>
      <buffer_size>0x8000</buffer_size>
      <loader>loader_f2.bin</loader>
     </device>

In the terminal, i get more information:

I remark that the chip_id does not correspond to the one in the devices.xml file. Should i change it? Is 0x411 an incorrect one?
