I’m proting mbed os to a custom stm32f407 board and trying to following the guide from TM32F407VET6 black board project. The link is : https://os.mbed.com/users/hudakz/code/STM32F407VET6_Hello/.
The blink project is running well if I use the online compiler, bin is successfully generated and programed to my board. Then I tried to export the project to uVision, then the errors occur as shown in attached picture. It seems some config error in uVision. Is there anyone know how to solve it?
