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,

 Inside your project folder. Where CMakeLists.txt and prj.conf are located.

HI,

thne command west  is not recognized.

what can I do?

Hi,

I am sorry for the late reply. Perhaps 'west' is not in PATH? You must have installed it since 'west' is part of the toolchain for nRF Connect SDK. It should have been installed automatically if you were using the 'Toolchain Manager' or you can take a look at 'Installing manually'.

Hi

I have used the toolchain Manager of nRF Connect SDK

I need to reinstall all?

[Marjeris Romero]

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.

[Marjeris Romero]

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