Hi,I find the DAPLink cannn't Use STM32F446 as the target processor.
When work in openocd :Could not find MEM-AP to control the core.

When work in keil only can read IDCORD，can‘t read the device name.
the STM32F446 can use jlink ,and operating normally,and the daplink can be used in STM32F103C8 and STM32F407VE.
