Error while buiilding in NiosII Eclipse EDS

--- Quote Start ---

Hi,

I am trying to run a simple hello world application by using New Nios II Application and BSP from template option in NiosII EDS. After selecting my sopcinfo file, choosing my sample project (hello world) when I click on build project to generate my elf file, I get the following error :

alt_sys_init.c.text+0xb8): undefined reference to `__alt_invalid'

collect2: error: ld returned 1 exit status

make: *** [Test_on_actual_design.elf] Error 1

How can I solve this error?

Thanks.

Try right clicking on your XXX_bsp folder and selecting NIOS 2, then generate BSP. Following, clean the project.
