error: no memory region specified for loadable section `.reset'

--- Quote Start ---

Hi,

I met a error when I compile the example (in C) in the NiosII SBT.

error: no memory region specified for loadable section `.reset'

Do anybody know why this error appeared?

I have specified the address of the reset vector in the SOPC builder

and just trying to test the DE1_Media_Computer programs which are

provided as reference designs.

The strange thing is when I run small examples like getting_started_C

or floating_C it works. But the error above appeared when running

larger examples like interrupt_example_C or test_Media_Computer_C.

Thank you in advance.

Best,

Dong

Hi Dong!

I realize this post is 2 years old. But I am having the same issue as you did. I have searched a lot on the forums but could not find a solution. How did you solve this problem?

There is a small bit of code that the NIOS2 jumps to when it is reset which might, for example, copy code from FLASH to RAM. Your reset vector needs to point at a properly tagged memory region where this code will reside.

You might have a look at the map file using the -Map mapfile option to nios2-elf-ld and or "nios2-elf-objdump -h <xxx.exe>", and or at your linker script.

Thanx Jeffrey. I found a doc that talked about memory assignment and I added a mapping for '.reset' in the linker script. That seemed to take care of the issue. There is another problem though.. I am trying to implement the DE1_Basic _Computer. The projects builds and compiles. But only the red LEDs light up; the 7 Seg and the green LEDs don't work. I guess because the 8 second timer is not being incremented in the exception handling and interrupt service routines. I have tried to find the documents and PDFs relating to this but could not find a solution. Do you have a suggestion?

Thanks once again.
