错误一：

d:/intelfpga/17.1/nios2eds/bin/gnu/h-x86_64-mingw32/bin/../lib/gcc/nios2-elf/5.3.0/../../../../../H-x86_64-mingw32/nios2-elf/bin/ld.exe: test.elf section `.text' will not fit in region `ram_oc_xzs'
d:/intelfpga/17.1/nios2eds/bin/gnu/h-x86_64-mingw32/bin/../lib/gcc/nios2-elf/5.3.0/../../../../../H-x86_64-mingw32/nios2-elf/bin/ld.exe: region `ram_oc_xzs' overflowed by 73212 bytes
collect2.exe: error: ld returned 1 exit status
make: *** [test.elf] Error 1原因：从这句话“ region `ram_oc_xzs' overflowed by 73212 bytes”中可以知道，ram_oc_xzs内存太小，可以在qsys中修改大小。

解决方法：

1、在qsys中修改大小

2、减少代码的大小（当板子的资源不足时）

错误二：

Error executing 'nios2-bsp-generate-files --bsp-dir . --settings settings.bsp', unexpected return code 1.Error message:SEVERE: BSP not valid.
SEVERE: BSP not valid.
SEVERE: nios2-bsp-generate-files failed.

解决方法：

错误三：

原先代码是在sdram跑的，然后改到了在片上ram_oc_xzs中跑，出现问题。

Error executing 'nios2-bsp-generate-files --bsp-dir . --settings settings.bsp', unexpected return code 1.Error message:SEVERE: [Error] hal: <b>hal.linker.exception_stack_memory_region_name</b> "sdram" is out of range: "none", "ram_oc_xzs_BEFORE_EXCEPTION", "ram_oc_xzs", "dual_port_ram", "reset", "epcs"
