Problem when building a project from template in Eclipse

996 Views

Hello everyone,

I have a problem when trying to build a project from a template in the Nios II Eclipse IDE.

I have generated and successfully programmed to the FPGA (the Deo0 Nano) a simple system consisting of a Nios II processor, a JTAG interface, an onchip memory, 4 input switches, 4 output leds and a SDRAM memory.

When I create in Eclipse a new project (with the option "Nios II application and BSP from template") and select the "Hello World" template, when I try to build it I get this error:

alt_sys_init.c: (.text+0x44): undefined reference to `__alt_invalid'

collect2: ld returned 1 exit status

make: *** [Lights_program_5.elf] Error 1

Nevertheless, if I create the program from the template "Hello World Small" I don't get this error and the program works fine.

Does anyone know where this error comes from?

Thank you very much,

Nacho
