Hi All, I am working on stm32f779i eval board with system work bench IDE, I am fatfs_uSD_RTOS example project in SDK_V1.8.0.

I am able to create a timer in this project and make it work, But when I changed RAM to SDRAM configuration in the linker file and for using (followed sample project for SDRAM). All my communications are working (CAN,SD, RTOS) but timer and watchdog timer are not working(Timer call back is not calling in the code once timer is expired).

Can anyone help me what is problem of SDRAM on timer functionalities ?

There probably will be no direct relationship to SDRAM.

You should verify that the timer and watchdog initializations run as intended, e.g. by placing a breakpoint to the routines where the timer and watchdog are initialized, and verifying that the processor passes through it.
