Hi,

 

I got the following error when I try to run an example of RTX_Blinky from Tutorial: Cortex-M7 STM32 F7 Discovery Kit.

The example software zip file is from www.keil.com/appnotes/docs/apnt_280.asp.

 

C:\Keil_v5\ARM\PACK\Keil\STM32F7xx_DFP\2.9.0\Drivers\STM32F7xx_HAL_Driver\Src\stm32f7xx_hal_rcc.c(481): error: #20: identifier "LSE_STARTUP_TIMEOUT" is undefined.

 

Please advise me how to solve the problem.

Thiha Kyaw
