Honored Contributorhi,i compile a zlggui under nios2 IDE(ver9.0),it comes on the error message:
Unable to reach disp_color (at 0x00000000) from the global pointer (at 0x00191328) because the offset (-1643304) is out of the allowed range, -32678 to 32767. But the same code under Keil(C51) and ADSv1_2(ARM) has no errors,Does NiosIDE have this Bug?
Honored ContributorAnyone has time,help me to do a try!thanks
how to post a accessory to this forum? I want to upload the source code.Honored ContributorHello I'm having the same problem on nii.ver 8.0. I'm still not able to solve it myself but I found that in the following documentation:
http://www.altera.com/literature/hb/nios2/n2sw_nii52004.pdf On page 42 It suggests that you might be using more than the 64K memory for small global pointers. try the -G 4 option in Project -> Properties -> ... -> C/C++ Build -> Tool Settings -> General->Compiler Options -> -G 4. That will allocate only pointers of up to 4B in the small global pointer region. As for myself I think the problem has to do with some very large Structs I use for holding frames and trying to pass a global pointer to them. I may try to pass smaller chunks of data If I don't solve the issue. Hope this helps, Have a great week. regards, Jonathan.
