Hello All,
I am using custom board using stm32f446ret7 controller. I am creating a sample project using CUBEMX for this stm32f446re controller and trying to flash using st-link/v2. But has got one warning as below. Can anyone help in understanding whether this warning affect any reset issue on board? is this can be neglected (complete logs are attached below for reference)?
Warn : STM32 flash size failed, probe inaccurate - assuming 512k flash
We are facing flashing issue on this custom board as below,
