How to place a variable into the CCM SRAM using the scatter file?

[Jhon]

I'm using the arm_rfft_fast_f32 function, I write a scatter file and place some library files in the CCM SRAM like below, and the speed is faster.

 RW_IRAM2 0x10000000 0x00002800 { ; CCM SRAM 10kB

  .ANY (ccmram)

arm_rfft_fast_f32.o (+RO)

arm_cfft_f32.o (+RO)

  arm_cfft_radix8_f32.o (+RO)

arm_rfft_fast_init_f32.o (+RO)

 }

but the twiddleCoef tables in arm_common_tables.o are too large to fit into the CCM SRAM, how to place the table "twiddleCoef_256" into the CCM SRAM specifically? Other tables are useless in my app.

Thanks!
