System Workbench for STM32


Re: STM32F446V support

Yes, SW4STM32 supports STM32F446 mcus and STM32446E-EVAL board. Are you using this board ? It looks like there is an issue with power supply. Did you change the default position of the jumpers ?

Thanks for hint, anyhow it is not STM32446EVAL!

I was using 3pin SWO connection and the problem was lack of MCU power on STLINKV2. Connecting pin1 to pin19 of 20 pin JTAG fixed it.
