Hi,

I resolved the issue and it's working after putting the custom UART overlay file into the mcuboot.

Thanks.

Hello,

Sorry for the long response time I took here. I am still looking into this. I tried to build the same sample in NCS V2.2.0 and I am getting some issue and I have contacted my colleague (author of repository) about this.

Have you included CONFIG_MCUMGR_SMP_UART=y config in your file? And which SDK version are you trying with?

Kind Regards,

Abhijith

Hi,

Yes, I disabled the Mass Storage Mode. This is my connection profile

root@12050445:/real# ./mcumgr conn show
Connection profiles: 
  acm0: type=serial, connstring='dev=/dev/ttymxc6,baud=115200,mtu=512'

And this is the detailed error I'm getting while attaching the log-level flag for mcumgr

Error: NMP timeout

To add more context, when I flash the SMP_SVR example (from samples) the same mcumgr commands work (with the same port) and I'm able to send mcumgr commands without a timeout; only with this serial recovery method, I get this timeout(loading from the bootloader).

I added a custom board overlay to the above project. Other than that, I haven't made any changes.

My custom overlay is,

&uart0 {
	current-speed = <115200>;
	status = "okay";
};



/ {
	chosen {
		zephyr,console = &uart0;
		zephyr,shell-uart = &uart0;
		zephyr,uart-mcumgr = &uart0;
		zephyr,bt-mon-uart = &uart1;
		zephyr,bt-c2h-uart = &uart1;
		zephyr,ot-uart = &uart0;
	};
};

&pinctrl {
	uart0_default: uart0_default {
		group1 {
			psels = <NRF_PSEL(UART_TX, 0, 29)>,
					<NRF_PSEL(UART_RTS, 1, 13)>;
		};
		group2 {
			psels = <NRF_PSEL(UART_RX, 0, 31)>,
					<NRF_PSEL(UART_CTS, 1, 15)>;
			bias-pull-up;
		};
	};

	uart0_sleep: uart0_sleep {
		group1 {
			psels = <NRF_PSEL(UART_TX, 0, 29)>,
				<NRF_PSEL(UART_RTS, 1, 13)>,
				<NRF_PSEL(UART_RX, 0, 31)>,
				<NRF_PSEL(UART_CTS, 1, 15)>;
			low-power-enable;
		};
	};

	uart1_me: uart1_me {
		group1 {
			psels = <NRF_PSEL(UART_TX, 0, 9)>;
		};
		group2 {
			psels = <NRF_PSEL(UART_RX, 0, 10)>;
			bias-pull-up;
		};
	};

	uart1_sleep_me: uart1_sleep_me {
		group1 {
			psels = <NRF_PSEL(UART_TX, 0, 9)>,
				<NRF_PSEL(UART_RX, 0, 10)>;
			low-power-enable;
		};
	};
};

&uart1 {
	status = "okay";
	current-speed = < 0x1c200 >;
	pinctrl-0 = < &uart1_me >;
	pinctrl-1 = < &uart1_sleep_me >;
	pinctrl-names = "default", "sleep";
};

Hello,

Have you tried disabling the Mass storage?

Could you share your connstring and type in the mcumgr script ?And are you getting any error logs while doing this?

Kind Regards,

Abhijith
