deca_compat.c:(.text.dwt_probe+0x94): undefined reference to `__dw_drivers_start'

c:\st\stm32cubeide_1.8.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.9-2020-q2-update.win32_2.0.0.202105311346\tools\arm-none-eabi\bin\ld.exe: deca_compat.c:(.text.dwt_probe+0x98): undefined reference to `__dw_drivers_end'

```

when i searched the '__dw_drivers_start' only exists in the flash of F4 .

can i modify the flash of WB and create other sections

[Markus GIRDLAND]

Yes, you can create sections as you please in the linker script of the WB.

Is this symbol supposed to be defined in the linker script or in the a library or in c code?
