Hi Maurizio,

May I know what was the error you got ?

You may need to verify if the memory section name is same as the one in your Nios II BSP or hardware.

Also, the __attribute__ must be placed in a function prototype.

Thanks.

Hi Eric, for example I tried to place an ISR function in my internal RAM (called RAM) in a section called “.myfastcode”: please refer to attached image for my memory sections in BSP. The function declaration is “void handle_timer_interrupt(void* p) __attribute__ ((section (".RAM.myfastcode")));”. When I build the project, this error appears: “section .RAM.myfastcode loaded at [000000000100d22c,000000000100d337] overlaps section .rodata loaded at [000000000100d22c,000000000100d3ab]”. Note that the overlap is in the “HRAM” address space, while I have declared my section to be in “RAM”. The same error appears even if I try to put my function in “.myfastcode” section instead of the previous “.RAM.myfastcode”. Any suggestion is welcome Thanks in advance Maurizio
