Thank you RK and Bjorn,

Its working now, I changed RAM origin and length accrodingly.

From the S132 API documentation of sd_ble_enable

NRF_ERROR_NO_MEM : The amount of memory assigned to the SoftDevice by *p_app_ram_base is not large enough to fit this configuration's memory requirement. Check *p_app_ram_base and set the start address of the application RAM region accordingly.

Sorry, it is NRF_ERROR_NO_MEM , err_code = 4

sd_ble_enable() doesn't return the error code '5'. Have another look.

Here is my linker script, please suggest me, if anything I needed to edit in this

/* Linker script to configure memory regions. */

SEARCH_DIR(.) GROUP(-lgcc -lc -lnosys)

MEMORY { FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000 RAM (rwx) : ORIGIN = 0x20001fe8, LENGTH = 0x6018 /** Location of bootloader setting in flash. */ BOOTLOADER_SETTINGS (rw) : ORIGIN = 0x0003FC00, LENGTH = 0x1000

}

SECTIONS { /* Place the bootloader settings page in flash. */ .bootloaderSettings(NOLOAD) : {

} > BOOTLOADER_SETTINGS

.fs_data : { PROVIDE(__start_fs_data = .); KEEP(*(.fs_data)) PROVIDE(__stop_fs_data = .); } > RAM } INSERT AFTER .data;

INCLUDE "nrf5x_common.ld"

err_code = 5 from the function 'softdevice_enable(&ble_enable_params);' and its same err_code from function sd_ble_enable(p_ble_enable_params, &app_ram_base) in softdevice_handler.c.

At the end it resets the nrf from function NVIC_SystemReset(); in __WEAK void app_error_fault_handler(uint32_t id, uint32_t pc, uint32_t info) in app_error_weak.c.

I think its related to RAM , here is my linker script

/* Linker script to configure memory regions. */

SEARCH_DIR(.) GROUP(-lgcc -lc -lnosys)

MEMORY { FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000 /RAM (rwx) : ORIGIN = 0x20001fe8, LENGTH = 0x6018/ RAM (rwx) : ORIGIN = 0x20001fe8, LENGTH = 0x6018 /** Location of bootloader setting in flash. */ BOOTLOADER_SETTINGS (rw) : ORIGIN = 0x0003FC00, LENGTH = 0x1000

}

SECTIONS { /* Place the bootloader settings page in flash. */ .bootloaderSettings(NOLOAD) : {

} > BOOTLOADER_SETTINGS

.fs_data : { PROVIDE(__start_fs_data = .); KEEP(*(.fs_data)) PROVIDE(__stop_fs_data = .); } > RAM } INSERT AFTER .data;

Thank you

stop it with a debugger, look at the error code before APP_ERROR_CHECK() checks it.

Thanks for your response. Could you suggest how to read error code? However, the effect of the error is that nrf restarts constantly, after the command APP_ERROR_CHECK(err_code).

well look up the error code and find out what it's telling you the error is, then fix the error.

We found that the exact error is at:

err_code = sd_ble_enable(p_ble_enable_params, &app_ram_base);

if (app_ram_base != ram_start)
{
    NRF_LOG_WARNING("sd_ble_enable: app_ram_base should be adjusted to 0x%x\r\n",
            app_ram_base);
    NRF_LOG_WARNING("ram size should be adjusted to 0x%x \r\n",
            ram_end_address_get() - app_ram_base);

}
else if (err_code != NRF_SUCCESS)
{
    NRF_LOG_ERROR("sd_ble_enable: error 0x%x\r\n", err_code);
}

return err_code;

Thus, in main.c, APP_ERROR_CHECK(err_code) is causing the nrf to restart. How do we resolve this? Thank you.
