Accessing FPGA RAM section

Hi nathan,

Check your linker script file -- it probably isn't assigning the int_ram section

to a memory region. You need something like the following

int_ram      : { *(int_ram)    } > int_ram

> UINT8 gc_buffer[8][1536] __attribute__ ((section ("int_ram")));

>

> This places the variable into the RAM.

This instructs the compiler to put the variable into a section

named "int_ram", it does not place the variable into a memory region.

The linker then uses "int_ram" as an input section. If you don't explicitly specify

an output section in your script, the linker will create an output section of the

same name.

Then, if the output section is not assigned to a specific region, the linker will

attempt to match attributes to locate the output section in an appropriate

memory region. In your case, it's being located to the same memory region

as .text & the two address spaces overlap -- so you should also see a

linker warning indicating that section int_ram isn't assigned to a memory

region.
