Flash Overflowed FOTA upgrade sdk 1.6.0 (Zephyr) nRF52

[Fb62]

Hello

I made an application on the nRF52 sdk, which works correctly.

Now I want to add the ability to update the firmware via OTA bluetooth.

I followed the instructions indicated at linkt https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/nrf/ug_nrf52.html#fota-upgrades

so my prj.conf file contains if following instructions;

CONFIG_BT = y

CONFIG_BT_BROADCASTER = y

CONFIG_BT_OBSERVER = y

CONFIG_BT_DEBUG_LOG = y

CONFIG_I2C = y

CONFIG_FPU = y

CONFIG_NEWLIB_LIBC = y

CONFIG_NEWLIB_LIBC_NANO = n

CONFIG_PWM = y

# Enable mcumgr.

CONFIG_MCUMGR = y

# Ensure an MCUboot-compatible binary is generated.

CONFIG_BOOTLOADER_MCUBOOT = y

# Enable flash operations. CONFIG_FLASH = y

# Enable most core commands.

CONFIG_MCUMGR_CMD_IMG_MGMT = y

CONFIG_MCUMGR_CMD_OS_MGMT = y CONFIG_MCUMGR_CMD_STAT_MGMT = y

CONFIG_MCUMGR_SMP_BT = y

And the main is the following:

#ifdef CONFIG_MCUMGR_CMD_OS_MGMT

#include "os_mgmt / os_mgmt.h"

#endif

#ifdef CONFIG_MCUMGR_CMD_IMG_MGMT

#include "img_mgmt / img_mgmt.h"

#endif

#ifdef CONFIG_MCUMGR_SMP_BT

#include "mgmt \ mcumgr \ smp_bt.h"

#endif

K_THREAD_DEFINE (rtc_task_id, STACKSIZE, Rtc_Task, NULL, NULL, NULL, PRIORITY, 0, 0);

K_THREAD_DEFINE (I2CManager_id, STACKSIZE, I2CManager, NULL, NULL, NULL, PRIORITY, 0, 0);

K_THREAD_DEFINE (bletxrx_id, STACKSIZE, BleTxRx, NULL, NULL, NULL, PRIORITY, 0, 0);

K_THREAD_DEFINE (Clock_id, STACKSIZE, ClockManager, NULL, NULL, NULL, PRIORITY, 0, 0);

void main () {

os_mgmt_register_group ();

img_mgmt_register_group ();

smp_bt_register ();

while (1) k_sleep (K_MSEC (10000));

}

When I build the solution, I get the following error:

region `FLASH' overflowed by 46088 bytes

see image below 

What steps should I take to solve the problem?

Thanks in advance

Hi,

Which nRF5 device are you working with? FOTA uses dual-bank update, which means you need to have double the flash size of the application available. Try running

west build -t rom_report

to see how much flash the different libraries on the application are using.

Best regards,

Marjeris

HI,

I'm using nRF52dk_NRF52852,

in witch directory i use the command 

west build -t rom_report

Tanks

HI 

I execute the command :  build -t rom_report,  (in the build_crf52dk_nrf52832 directory and get this error:

I need help to integrate the FOTA in my application.

Tanks in avance.

HI,

OK thank you.
I have the nRFDK_nRF52832, so to test the FOTA I modified the code of the blink example, adding the following activations in the prj.conf

CONFIG_GPIO=y

# Enable mcumgr.
CONFIG_MCUMGR=y

# Ensure an MCUboot-compatible binary is generated.
CONFIG_BOOTLOADER_MCUBOOT=y

# Enable flash operations.
CONFIG_FLASH=y

# Enable most core commands.
CONFIG_MCUMGR_CMD_IMG_MGMT=y
CONFIG_MCUMGR_CMD_OS_MGMT=y
CONFIG_MCUMGR_CMD_STAT_MGMT=y
CONFIG_MCUMGR_SMP_BT=y

I added the bluetooth.c file taken from the smp_svr example to the project, and I modified the main in this way .

led_is_on = !led_is_on;
k_msleep(SLEEP_TIME_MS);

}
}

The project is compiled without errors, and start.

Activated nRF Connect on my phone, I see the Zephyr connection, I can connect, I select the DFU button, I select the app_update.bin file generated, but the update procedure stops during validation.

Could you help me understand where I went wrong.

Thanks in advance
