RAM retention problem

[enkavak]

Hello,

      I'm using nRF5 SDK with version 15, nRF52832 IC and softdevice s132. I need to save hold the data in the ram even in sleep mode. I'm using the below code. However it did not resolved my issue. 

 sd_power_ram_power_set(4,(POWER_RAM_POWER_S0POWER_On << POWER_RAM_POWER_S0POWER_Pos) |
    (POWER_RAM_POWER_S1POWER_On << POWER_RAM_POWER_S1POWER_Pos) |
    (POWER_RAM_POWER_S0RETENTION_On << POWER_RAM_POWER_S0RETENTION_Pos) |
    (POWER_RAM_POWER_S1RETENTION_On << POWER_RAM_POWER_S1RETENTION_Pos));

what about the size of the ".retained section" in placement file ? It is specified as "8" in "ram_retention_softreset_clean".  Is it 8 bytes or 8 RAM sections?

#define __retention __attribute__((section("retention_mem_area0"), zero_init)) // essential

What do you need to add?
