Truncation Error

When ever I switch my NIOSII uCOSII project from being stored in onchip_memory to ext_flash I get the following error: 

 

In function 'alt_irq_handler': 

/cygdrive/c/altera/90/nios2eds/components/altera_hal/HAL/src/alt_irq_handler.c:98: relocation truncated to fit: R_NIOS2_CALL26 OSIntEnter 

 

/cygdrive/c/altera/90/nios2eds/components/altera_hal/HAL/src/alt_irq_handler.c:98: relocation truncated to fit: R_NIOS2_CALL26 OSIntExit 

 

I've stored larger projects than this in ext_flash before, any idea what this is? 

 

Thanks

Hi, ThePhil, 

 

Just wondering whether you have this issue fixed and 

find out the source of error. 

 

I encounter similar problem in my project and would like 

to learn from your experience. 

 

Best regards, 

 

Kevin

I got the similar problem when using Quartus II 9.1 and 

I fixed it by changing the setting of Nios II processor in SOPC Builder. 

 

As shown in attached picture, the memory segment for "Reset Vector" should be the same as that in the property of system library "Program memory (.text)". 

 

Also, I found that memory segment for "Exception Vector" would be put together within segment for .text from the linker script that is automatically generated by Nios II tools. Therefore, I think this memory should be set as the same as "Reset Vector". 

 

You can see this linker script from path: 

\software\XXX_syslib\Debug\system_description\generated.x

Well, alt_irq_disable_all() works. But If I change that line of code to alt_irq_disable(TIMER_INTERRUPT) it doesnt work anymore.
