Great!!

This change in the process of generation of .zip package resolves my issue.

Thanks for your patience and support.

[quote user="RahulR"]I am using Soft Device s130 2.0.0. [/quote]

s130_nrf51_2.0.0 should use 0x80 for --sd-req.

Could you try this?

nrfutil.exe pkg generate --application application.hex --application-version 1 --application-version-string "1.0.0" --hw-version 51 --sd-req 0x80 --key-file private.key %file_name%.zip

I am using Soft Device s130 2.0.0. Below is the command used for generating .zip package.

nrfutil.exe pkg generate --hw-version 51 --application-version 0xFFFFFFFF --application application.hex --sd-req 0xfffe --key-file private.key %file_name%.zip

Hi,

[quote user="RahulR"] Yet I am getting failure in downloading .zip package.[/quote]

What is the error message? How do you generate the .zip package? What is the command? If you use s130_nrf51_2.0.1_softdevice.hex, you generate the pack with the command like this if you use the correct key:

nrfutil pkg generate --application dfu_test_app_hrm_s130.hex --application-version 1 --application-version-string "1.0.0" --hw-version 51 --sd-req 0x87 --key-file private.pem FW.zip

Another way I tried is, first I flashed Boot-loader and Soft Device through nrfConnect Programmer and then generated hex.zip package from Application hex file.

I used nrfConnect android App to flash .zip package.

It followed steps:

1. Connecting

2. Starting bootloader

3. Disconnected (Without initiating download)

I double checked the private key used to generate .zip package and same key was used to generate public_key.c file that was used to build the boot-loader. Yet I am getting failure in downloading .zip package.

Well, I repeated all the steps related to generation of keys to ensure that there is no mismatch. Yet Application is failed to operate normal.

It reads DfuTarg in the broadcast scan data

If you only program the bootloader and the softdevice, could you see it advertising as DfuTest?

Is the Public key the same pair of the private key with the application?

I generated boot-loader hex file from SDK 12.1.0 with Public key added. I did not make any other changes.

Hi,

Where is the new boot-loader from? Is it your code or the example? Could you test with the example bootloader without modification? If you only program the bootloader and the softdevice, could you see it advertising as DfuTest?

Not yet Amanda.

I am still facing issue with new boot-loader. I shared memory map with older boot-loader for reference.

Can you check what's wrong with this memory map?

Address Range
3FC00 - 3FD5B => 348 bytes
Bootloader
3AC00 - 3FADB => 20188 bytes
Application
000000 - 40000 => 262144 bytes
Application
1B000 - 28FDF => 57312 bytes
Soft Device
1000 - 1AFFF => 106496 bytes
MBR or Application
0000 - 7BF => 1984 bytes

Below is the memory map after writing flash with new boot-loader

The issue with this is Application is not starting normal.

While below is the memory map after writing flash with older boot-loader (keeping application.hex same)

Address Range
3FC00 - 3FFFF => 1024 bytes
Application
000000 - 40000 => 262144 bytes
Bootloader
39800 - 3CB77 => 13176 bytes
Application
000000 - 40000 => 262144 bytes
Application
1B000 - 28FE7 => 57320 Bytes
Soft Device
1000 - 1AFFF => 106496 bytes
MBR or Application
0000 - 7BF => 1984 bytes

With this, application is functioning normal.

Hi,

Please see the Memory layout for Memory range nRF51 (S130 v2.0.x).

With these memory address ranges, I am able to write all 3 hex files successfully.

Thanks for you help.

But I want to be cautious about the memory addresses defined for Application hex file. This is how it looks now. I noticed that Application is not operating correctly.

Would you please suggest better address range for Application hex file? as this seems to be colliding with boot-loader.

Hi RahulR,

Could you set IROM1 and IRAM1 like the following for the bootloader and build the image again?

-Amanda H.

RE: 12.1.0 nRF5 SDK Bootloader size issue

RahulR — Mon, 29 Jun 2020 04:07:12 GMT

I did not make any changes to memory settings. Same values are preloaded in the boot-loader.

Is there any way to reduce boot-loader size?

Note: I have disabled logging

Boot-loader and Soft Device files have overlapping data.

Hi,

nRFGo studio is deprecated and replaced by the programmer app in nRF Connect for Desktop. That might explain why you get the error. I would recommend using the nRF Connect Programmer app.
