stm32f4-disco USART3 st link baudrate switch problem

SBolt.1

Dear Sirs or Madames,

I have a stm32f4-disco board with an adafruit winc1500 wifi shield. The firmware update and the update of the ssl certificates for the winc1500 are carried out via a serial bridge. While updating I have to switch a few times USART baudrate from 115200 to 500000 and vice versa. If I do this on USART3 stlink debug interface sometimes sent packages were lost. If I use USART6 which is without stlink debug interface everything works fine. Do you have any idea what could be the problem? Thanks in advance.

Best regards

Sebastian
