Failing to configure USB console and SW update

[SvenDufva]

I'm trying to enable USB for console and SW update over USB but failing miserably.

I'm getting errors:
zephyr/drivers/console/libdrivers__console.a(uart_console.c.obj): in function `uart_console_init': v2.4.2\zephyr\drivers\console\uart_console.c:613: undefined reference to `__device_dts_ord_124'

and

zephyr/drivers/console/libdrivers__console.a(uart_console.c.obj): in function `console_out': zephyr\drivers\console\uart_console.c:110: undefined reference to `__device_dts_ord_124'

My related .dts definitions are as follows:

/ {
	chosen {
		zephyr,console = &cdc_acm_uart0;
		zephyr,shell-uart = &cdc_acm_uart0;
		zephyr,uart-mcumgr = &cdc_acm_uart0;
		zephyr,bt-mon-uart = &cdc_acm_uart0;
		zephyr,bt-c2h-uart = &cdc_acm_uart0;
		zephyr,bt-hci-rpmsg-ipc = &ipc0;
		// nordic,802154-spinel-ipc = &ipc0;
		// zephyr,ieee802154 = &ieee802154;
	};
};

zephyr_udc0: &usbd {
	compatible = "nordic,nrf-usbd";
	status = "okay";

	cdc_acm_uart0: cdc_acm_uart0 {
		compatible = "zephyr,cdc-acm-uart";
		status = "okay";
	};
};

The flags that trigger the error are:
CONFIG_CONSOLE=y
CONFIG_UART_CONSOLE=y
CONFIG_MCUMGR_TRANSPORT_UART=y
CONFIG_UART_CONSOLE_MCUMGR=y
CONFIG_RTT_CONSOLE=y

When looking the driver code, it should pick zephyr,console definition but for some reason, it is not included in the build...

Hi,

Could you locate the file below in your build folder and tell me which peripheral matches the ord number. They are listed at the start of the file.

    build\zephyr\include\generated\devicetree_generated.h

If you rebuild, check if the number in the __device_dts_ord_124 part of the error message changes from 124 to something else.

I assume that USB configs are enabled? For example CONFIG_USB_CDC_ACM=y
And that uart0 is enabled?

[SvenDufva]

I'm not seeing anything starting with "__device_dts" in the devicetree_generated.h. 

Chosen nodes have been converted into:

#define DT_CHOSEN_zephyr_console                          DT_N_S_soc_S_peripheral_50000000_S_usbd_36000_S_cdc_acm_uart0
#define DT_CHOSEN_zephyr_console_EXISTS                   1
#define DT_CHOSEN_zephyr_shell_uart                       DT_N_S_soc_S_peripheral_50000000_S_usbd_36000_S_cdc_acm_uart0
#define DT_CHOSEN_zephyr_shell_uart_EXISTS                1
#define DT_CHOSEN_zephyr_uart_mcumgr                      DT_N_S_soc_S_peripheral_50000000_S_usbd_36000_S_cdc_acm_uart0
#define DT_CHOSEN_zephyr_uart_mcumgr_EXISTS               1

I've CONFIG_USB_CDC_ACM=y as well as CONFIG_SERIAL=y (I'm using other UARTs in the solution).

UART0 is enabled through dts file as follows (do I need to have it there even though I'm using USB UART emulation):

&uart0 {
	compatible = "nordic,nrf-uarte";
	status = "okay";
	current-speed = <115200>;
	pinctrl-0 = <&uart1_default>;
	pinctrl-1 = <&uart1_sleep>;
	pinctrl-names = "default", "sleep";
};

Could you zip and attach your project? Or reproduce it in a sample and attach that?

[SvenDufva]

Thanks for taking the time to look into this. I attached carved out version that still produces the error.

Hi again, I found the issue. You need to set up mcuboot for the usb/uart console. Take a look at these samples, especially the configs in child_image/mcuboot.conf:
