Hi

This works fine for me as well, but when I try to place a variable in the same memory, I get an error about causing a section type conflict.

Just to make clear: I have a program running from sdram. Then I want to have a variable in onchip memory as well as another function in onchip memory. Here is the code

int func(void) __attribute__ ((section (".onchip_ram")));

Is there any known problem placing both of these in the same memory ?
