Sysbuild example nRF5340DK UART output

[danny0007]

Hi Community,

I'm learning the sysbuild stuffs, try to upgrade my code to sdk v2.9.0.

Exercise 2 - Adding custom image - Nordic Developer Academy

I'm using nRF5340DK to run this exercise code, but I can't find the so called "UART30 " for output.

Could you please give me more instructions? thanks!

Regards

Danny

Hi,

Only the nRF54L15 uses the FLPR core. The nRF5340 uses the Network core, which is on UART0.

The COM port settings in Windows does not match to UART name

Hi Sigurd Hellesvik 

I want to upgrade my code to sdk v2.9.0.

Exercise 4 – DFU over USB 

Exercise 5 – FOTA over Bluetooth Low Energy

these two features I need for my use case, I know they are currently only supported for nRF5340DK. I tried to compile DFU over USB for thingy53, seems not working.

could you please share me how to make them also working for thingy53? because my board is similar as thingy53.

Regards

yes,

I need to upload two bin files separately and give them a number 0 and 1:

it works in this way.

is it somehow possible to use the dfu_application.zip directly?

Hi Sigurd Hellesvik 

build the FOTA ncs-inter/l9/l9_e5_nrf5340_both_sol at main · NordicDeveloperAcademy/ncs-inter for Thingy53, 

Cannot find any discussion regarding this kind of error, maybe nobody tried this, could you please have a look:

---- Reopened serial port COM28 ----
*** Booting My Application v3.0.0-b901c3efa989 ***
*** Using nRF Connect SDK v3.0.0-3bfc46578e42 ***
*** Using Zephyr OS v4.0.99-3e0ce7636fa6 ***

Thanks and Regards

It is not. The nRF SoC can not handle the .zip file. This is required by the app that sends the update.
When you select dfu_application.zip in the Android app, the nrf Android app will unzip it automatically and send the images in order.

My guess is that this error is because the radio core fails, and therefore, the application core can not communicate with it over HCI.

Hi Sigurd Hellesvik 

I compared the board files of nRF5340DK and Thingy53 one by one, still cannot make it working.

could you please compile the FOTA code for Thingy53 and take a look? thanks.

Hi @Sigurd Hellesvik 

after changing the code in thingy53_nrf5340_common.dtsi to this:

    chosen {

        //zephyr,bt-hci-ipc = &ipc0;

        zephyr,bt-hci = &bt_hci_ipc0;

        //nordic,802154-spinel-ipc = &ipc0;

        //zephyr,ieee802154 = &ieee802154;

        //nordic,pm-ext-flash = &mx25r64;

    };

changing the code in thingy53_nrf5340_cpunet.dts to this:

    chosen {

        //zephyr,console = &uart0;

        //zephyr,shell-uart = &uart0;

        //zephyr,uart-mcumgr = &uart0;

        //zephyr,bt-mon-uart = &uart0;

        //zephyr,bt-c2h-uart = &uart0;

        zephyr,bt-hci-ipc = &ipc0;

        //nordic,802154-spinel-ipc = &ipc0;

        zephyr,sram = &sram1;

        zephyr,flash = &flash1;

        zephyr,code-partition = &slot0_partition;

        zephyr,ieee802154 = &ieee802154;

    };

the FOTA code for both cores is running, the HCI error is gone, but I'm not sure if it's a reliable solution, please double check it.

**********************************************************************************

Additionally, since I only have USB on my board, for debugging I want to redirect the logging and output of printk to USB, so I add following code in app.overlay 

/* Step 1.1  - Add external flash to applciation */

/ {

    chosen {

        nordic,pm-ext-flash = &mx25r64;

        zephyr,console = &cdc_acm_uart0; //for printk in app

    };

};

 

&usbd {

    cdc_acm_uart0: cdc_acm_uart0 {

        compatible = "zephyr,cdc-acm-uart";

        status = "okay";

    };

};

and this in prj.conf:

# Enable USB subsystem

CONFIG_USB_DEVICE_STACK=y

CONFIG_UART_LINE_CTRL=y

CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=y

CONFIG_USB_DEVICE_PRODUCT="TEST_USB"

CONFIG_STDOUT_CONSOLE=y

CONFIG_LOG=y

 

but this crashes the system often, the chip get rebooted very often, how can I make a reliable USB logging?
