Hi,

It seems you have mixed up with the softdevice RAM size with the application RAM size, that you set in the linker file.

To maximize the available RAM for application, the RAM ORIGIN should be set to 0x20000000 + softdevice_ram_size, and the length should be set chip_ram_size - ram_origin. For your setup, the MEMORY settings in the linker file should look like this (for nRF52832_xxAA chip):

MEMORY
{
   FLASH (rx) : ORIGIN = 0x2D000, LENGTH = 0x53000
   RAM (rwx) :  ORIGIN = 0x20001F30, LENGTH = 0xE0D0
}

Note that this RAM setting is the minimum required RAM size, your application will most likely need more. I would recommend setting the ORIGIN to 0x20004000 or 0x20005000, and check the minimum start value returned in p_app_ram_base by sd_ble_enable(). You can then change the RAM ORIGIN to this value.

Best regards,

Jørgen
