Help me to use ARM_DRIVER_UART API in Keil ARM MDK5

Hi,

Reasons for hitting FaultHandler can be different. In MDK5 UART depends on RTOS. Check for settings in RTX_Conf_CM.c file. You can edit it manually or via GUI. My current working settings are as follows:

Thread Configuration
 - Number of concurent running threads 6
 - Default thread stack size 200
 - Main thread stack 200
 - Number of of threads with user.... 0
 - Total stack size [bytes]...... 0
 - Check for stack overflow   ... checked
 - Processor mode.... Privileged mode

RTX Kernel timer Tick configuration
 - Use cortex-m systick.... checked
 - clock (depends on device)
 - timer tick value [us] 1000

Quite common reason can be too small stack size for threads. But this is just one small point for a possible fault. There can be other reasons as well.

Hope it helps.

Thank you so much Nixon! Using your settings there fixed the issue.

Much appreciated

Keil drivers have limited featues and some pheripherals have no keil driver, or some capabilities are missed in MDK5.

we work with ST driver lib but it is strange that keil will not support such perfect driver and use its buggy and incomplete driver.
