本人初学FPGA,最近在调一个最小系统的时候，因为我买的fpga开发板将sram flash都复用了同一总线（数据，地址）并且也引出了相对应排插，当我部署完最小系统的时候如果排插没有插入任何杜邦线，则使用官方测试内存模板
Testing RAM from 0x480000 to 0x49FFFF
-Data bus test passed
-Address bus test passed
-Byte and half-word access test passed
-Testing each bit in memory device. . .  passed
Memory at 0x480000 Okay
内存测试正常
可当我想将数据地址总线复用给其他外设(杜邦线连接）的时候，问题就出现了
Testing RAM from 0x480000 to 0x49FFFF
-Data bus test failed at bit 0x1
Press enter to continue or 'q' to quit.
或者是
Testing RAM from 0x480000 to 0x49FFFF
-Data bus test passed
-Address bus test passed
-Byte and half-word access test failed at address 0x480000
Press enter to continue or 'q' to quit.
新人问题幼稚，还请各位大虾见谅，十分感谢
