NRF5340DK Memory Access Problem

[faruk]

Hello all,

I have problem with flashing the code. It gives me memory protection error. 

Steps I followed for creating firmware and flashing:

1- I took a sample from nrf sdk as "bap_unicast_server"

2- I added a build configuration with followings ;

      * SDK V3.1.0

      * nrf5340dk/nrf5340/cpuapp

      * Generate and build

3- Flash

Then I got error with this log

What I tried to fix it;

1- I did recover device from connected device menu

2- I upgraded nrfutil by entering "nrfutil upgrade device" then flash again. Nothing is changed.

Hi, 

You can open the nRF Connect termainl to execute "nrfutil device recover" command. See Recovering a protected device.

It didnt help. I uploaded code one by one by using --domain. Now I read serial and get that message:

Not enough bytes ready, padding 320!<CR><LF>
<ESC>[1;31m--- 1 messages dropped ---<CR><LF>
<ESC>[0mNot enough bytes ready, padding 320!<CR><LF>

In prj.conf file log buffer is size as below;

CONFIG_LOG_BUFFER_SIZE=10240

Do you get any error log while executing "nrfutil device recover"? What does it return?

The log you get from the serial is your application log instead of tool log. 

I think it's returned by here https://github.com/nrfconnect/sdk-zephyr/blob/ncs-v3.1.0/samples/bluetooth/bap_broadcast_source/src/main.c#L203

It recovered but when I try to flash, the error message is the same as "memory protection issue".

When I flash network and app by using --domain <> --recover one by one, it solved flashing problem.

Another method is that adding mcuboot to application also solved my problem.
