Thx, I am looking for it.... Do you have any idea where I might find it?....

My new project target was setup as a STM32F4DISCOVERY boards, MCU STM32F407VGTx and it shows that setting in the Target Tab
Why does it insist I am targeting an STM32L Series?

Make sure you have the ST-LINK V2 software installed.

When you attach it you should get a new removable drive (like a USB Flash drive) added to your system.

In the device manager you should get a “Universal Serial Bus Devices” -> “STMicroelectronics STLink dongle” device.

You should also get a “Ports (COM & LPT)” -> “STMicroelectronics STLink Virtual COM Port” device.

The “ST Visual Programmer” should recognize it and be able to read from it.

Instead you have to check your debug configuration :
Menu > Run > Debug Configuration > select your config
in Main (TAB) make sure that the correct Project is selected
in Debugger (TAB) make sure that stm32f4discovery.cfg (or stm32f407g_disc1.cfg) is selected as default script
if not you have to check your project target (project properties > C/C++ Build > Settings > Target (TAB))

Edit:
Sorry I have answered without refreshing the browser, so I haven’t remarqued that your issue is solved.

Analysis:
when
(o) Use defult script
is used (see picture in post #5) there are at least 2 stm32f4discovery.cfg files in AC6 that could be used - they are different;

C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.debug_1.8.0.201603291114\resources\openocd\scripts\board
containing;
source [[find interface/stlink-v2.cfg]]
transport select hla_swd
source [[find target/stm32f4x.cfg]]
reset_config srst_only

C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.debug_1.8.0.201603291114\resources\openocd\scripts\st_board
containing;
source [[find interface/stlink-v2.cfg]]
source [[find target/stm32f4x_stlink.cfg]]
# use hardware reset, connect under reset
reset_config srst_only srst_nogate

it is NOT possible to see or control which is used from the dialog - since the browse button is grey.
the openocd console output/log also does not seem to show which is used.
