MQX Memory Direct Access ISSUE

Hi, This is Sungho from South Korea.

I`m using 'i.mx6sx-sdb' board to build some application with PURE MQX BSP/PSP library(with no config modifications).

I`m wondering why Direct Memory Accessing to peripherals makes  'MQX_AUTO_START_TASK' attributed Task stop...(may jumped to some exception handler...)

I didn`t set MQX_ENABLE_USER_MODE <= this #define when copmpiled with bsp.a/psp.a  


Is this MPU related issue? or Privileged Mode related issue? or RDC issue? or Clock Source Configure issue?

Memory Access Code is like this........reg = *(uint32_t *)0x020A8000;


Regarding MPU and Privileged Mode,

I searched all the BSP code but could not find the MPU configuration section.


Need a Help...please


Any replies will be appreciated.
