extrenal sram on emif1 for TMS320F28377D 测试,部分成功

Other Parts Discussed in Thread: C2000WARE
 tms320f28379 launchpad  内存扩展板  256k x 16 bit sram .  
 
 
 c2000ware  emif1 sram example for f28379d ("C2000Ware_1_00_06_00\device_support\f2837xd\examples\cpu1\emif1_16bit_asram") 工作正常
默认
#define ASRAM_CS2_START_ADDR 0x100000
#define ASRAM_CS2_SIZE 0x8000
32kx16 大小的sram测试
////////////////
改了 之后  各种 错误 
1
 ASRAM_CS2_SIZE to   0x8100   ,调试 得到   "ErrCount equals 1"
ASRAM_CS2_START_ADDR 0x107000
ASRAM_CS2_SIZE to   0x2100
又正常
ASRAM_CS2_START_ADDR 0x100000
 ASRAM_CS2_SIZE to   0x40000
程序 进 函数 "mem_read_write" 就死循环了 ,就是这几行
for (i=0; i < mem_size; i++)
{ *XMEM_ps++ = mem_wds;
mem_wds += 0x11111111; }
如何解决 大容量 内存的测试?
