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.
