Migration from STM32F105 board to STM32F411 board
Posted: Tue Apr 10, 2018 11:18 am
Hi everybody,
Right now I have the PCB card Designed for STM32F105.
Our objective is to use the same PCB card to STM32F411 by porting the SW application to the new library (Done).
- For the SW side we did all the recommended change based on the application note :
Migration of microcontroller applications from STM32F1 Series to STM32F4 Access lines
-For the HW side we made only one change on the board :
PB11 (STM32F105) -----> VCAP_1 (STM32F411) adding a capacitor.
As a result:
- Our application not stable "work for some seconds after that the micro-controller Hangup".
For the HW side have you any suggestion or recommendation?
- (We have the QFP64 package of STM32F411).
- Our application use I2C, UART 2 and USB-OTG for charging the battery.
Thanks in advance and Best Regards,
