Why NIOS 9.1 has such problem?

Question

The project works well with nios 8.0.But when i build it in nios9.1,it has two errors like this--

Description Resource Path Location Type

system_description/alt_sys_init.c error: `JTAG_UART_IRQ_INTERRUPT_CONTROLLER_ID' undeclared (first use in this function) all_syslib 89 C/C++ Problem

Is it because my pc has both 8.0 and 9.1 versions?Thanks

Recompile everything in v9.1.  Remember to refresh SOPC files in SOPC builder in v9.1.  In Nios II EDS 9.1, please refresh BSP too.

There is an option "BUILD BSP" under project option.  Right click on project_bsp, you should see it.
