[nRF Connect SDK]Questions for porting.

[Tim Hwang]

Hello.

Target nRF52832(nrf52dk_nrf52832)

SDK NCS v1.9.1

Build : SES for win 10 (5.68)

1. Support BT5.3

My project used nRF5_SDK_17.1.0_ddde560. Recently I found That SDK cannot support 5.3. (5.1 limited)

So I heard that have to use NCS(nRF Connect SDK), is it correct? 

2. Build mcuboot

Following is my base project.

C:\Users\user\ncs\v1.9.1\nrf\samples\bluetooth\peripheral_hids_keyboard

1) In order to build mcuboot, I add that in prj.conf, but I don't think mcuboot has no changes. no hex(bin)

CONFIG_BOOTLOADER_MCUBOOT=y

How I can build mcuboot?

2) I will use DFU via UART. How to add UART implementation in mcuboot? Can you give me good sample for me? 

3. Make my own pem for sign

: done. (C:\Users\user\ncs\v1.9.1\bootloader\mcuboot>scripts\imgtool.py getpub -k mykey.pem)

Now I have to put rsa_pub_key into keys.c. What keys.c should I use?

4. Make dfu image

Using MCUboot in nRF Connect SDK — MCUboot 1.8.99 documentation (nordicsemi.com)

I cannot find any bin in my project. Maybe I failed to build mcuboot, right?

Hi, 

Here is the https://github.com/NordicSemiconductor/pynrfjprog

Hello.

I could install pynrfjprog. But I'm expecting real sample.

here is my old sample. But it is not compatible with mcuboot.

nrfutil dfu serial -pkg dfu_application.zip -p COM30 -b 115200 -t 1 -cd 0 -prn 0

mcumgr is too slow. pynrfjprog don't have example.

How can I update my app via uart? I'm okay anything if it has good speed.

Hi, 

Python wrapper around the nrfjprog dynamic link libraries (DLL). The use of this API allows developers to program/debug nRF SOC. The nrfutil is another tool that is only supported by the nRF5 bootloader. Seems Zephyr doesn't have other tools than mcumgr to support mcuboot.
