softdevice,application and bootloader flash error

[Raju]

I have taken ble_app_ancs_c_s130_pca10028 example of sdk11,s130 version 2.0.0 and i integrated Alert Notification Service,DIS[device information service] and DFU... Device is advertising in NRF CONNECT..ANCS and ANS are working fine.when i try to flash softdevice ,application and bootloader in order to do DFU with the below specification..

The below specifications is for SOFTDEVICE,

FLASH (rx) : ORIGIN = 0x01000, LENGTH = 0x1B000

RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x1F80

The below specifications is for APPLICATION,

FLASH (rx) : ORIGIN = 0x0001B000, LENGTH = 0x3C000

RAM (rwx) : ORIGIN = 0x20002020, LENGTH = 0x4000

The below specifications is for BOOTLOADER,

FLASH (rx) : ORIGIN = 0x0003C000, LENGTH = 0x3C00

IRAM1 (rwx) : ORIGIN = 0x20002C00, LENGTH = 0x5380

IRAM2 (rwx) : ORIGIN = 0x20007F80, LENGTH = 0x80

ble_enable_params.common_enable_params.vs_uuid_count =VENDOR_SPECIFIC_UUID_COUNT; VENDOR_SPECIFIC_UUID_COUNT=8;

ble_enable_params.gatts_enable_params.attr_tab_size = 0x500;

from command line am getting as ERROR: THE area to write is not erased

from NRFGO STUDIO am getting ERROR as : this hex file has data in softdevice region. try programming using program softdevice or erase all before programming.

What could be the possible reason for facing these errors?....

Obviously you got error in linker script. Note that softdevice region begins at 0x01000 and is 0x1b000 long. So its end address is 0x0100 + 0x1b000 = 0x1c000 but your application starts at 0x1b000 (should be 0x1c000 !) the same situation is with bootloader and application - they overlay. What is more your flash region for application goes out of memory - on nrf51 you have either 0x20000 or 0x40000 bytes of memory.

I would recommend to check addresses in linker scripts provided by nordic.
