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

Best regards

No, I don't think so. If you have used the Toolchain Manager then it must be installed. Check if you have the directory in PATH variable.

In Windows you can open a terminal with cmd.exe and type 'echo %PATH%' to see which directories are included in PATH, if you cannot see the directory where 'west' is install then that's the problem.

You can be add the install directory for west in "Edit the system enviroment variables" in System Properties.

In the System Variables section (lower half) find the row with "Path" and add the installed directory for west.

Another thing you can do, is to open the command prompt from the toolchain manager:

HI 

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

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);
STATS_INC(smp_svr_stats, ticks);
}
}

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
