I am using STR912 and I have a external SRAM with 512KBytes.
Now I can read/write the external SRAM , but I cannot run my FreeRTOS kernel using external SRAM.
I modified the lnkarm_flash.xcl , but it cannot work :
// Data memory
-DRAMSTART=0x4000000
-DRAMEND=0x4018000
-DEXT_RAMSTART=0x38000000
-DEXT_RAMEND=0x38018000
//************************************************
// Data segments.
//************************************************
-Z(DATA)DATA_I=RAMSTART-RAMEND
-Z(DATA)DATA_Z,DATA_N=EXT_RAMSTART-EXT_RAMEND
I’m using IAR to develop my project , and using EMI bank 1 for SRAM.
Are there any other file need to modify ?
