Hi:
When I review MSPM0G_TRM_V06, I find page 48 as below:
SRAM map 3 regions, what is the difference? I find the data in 0x2000 0000 region is the same as the data in 0x2020 0000 region through watching the memory browser.
If I define MEMORY SRAM as :
SRAM (WX) : ORIGIN = 0x20200000, LENGTH = 0x00007800
In main function, I execute memcpy functions. If I copy data from 0x2020 7FF0 region, it can work normally, But if I copy data from 0x2000 7FF0, hard fault interrupt is occured.
memcpy(buffer1,0x20207FF0,4);
memcpy(buffer2,0x20007FF0,4);
if I write data in 0x0x20207FF0 first, and then execute memcpy functions(memcpy(buffer2,0x20007FF0,4)), it will not occur hard fault interrupt.
Can you help me check it out?
