Uploading Bootloader & application

[Asha]

Hi,

I have create a separate .hex file for boot-loader & application. when i try to load them into the nRF52382 through "nRF connect".

It says overwriting has occurred.

please let me know how to do flash the bootloader & the application without overloading issue.

Thank you in advance.

Adjust linker memory section of apllication in flash. Seems like you got MBR and application? Bootloader is at the end of the flash

can u please guide me, what i should do? because I'm new to this...

Hi, we have developed our Bootloader & application using VScode(using platformio) on Linux.

Controller using - nRF52382.

This is my bootloader program.

[env:adafruit_feather_nrf52832]

platform = github.com/.../platform-n-able.git#1.0.0

board = adafruit_feather_nrf52832

framework = arduino

board_bootloader = adafruit

;board_build.f_cpu = 64000000L

upload_protocol = jlink

debug_tool = jlink

my application program is simple blinking of LED.  I took the .hex files of these and trying to burn it through nRF connect.

When i bun it through VS code, there is no problem. But the same thing when i try to upload through nRF connect its overlapping.

When our product goes for mass production we cant give the source code for burning. So we prefer to give the .hex to burn

The problem is that you have two programs that overlap with each other in FLASH. I'm not familiar with PlatformIO, so I can't tell you where to change the linker settings, but that's probably what you need to do.

You can compare the *.map files from your build folders to see where overlap is.

Can you guide me how to write the bootloader program into MBR using nRF connect?

No, this is an issue with the linking of your FW images. Forcing the programmer load the FW to another address is not going to fix that.
