NMP timeout when i am using any mcumgr command

[CEmir10]

I followed all the instructions from https://docs.zephyrproject.org/2.6.0/samples/subsys/mgmt/mcumgr/smp_svr/README.html. Every time i try to use mcumgr command with nrf52840dk_nrf52840 I am getting nmp timeout error, even in case i msddisable and use -t <timeot.

crem@CHVL0365u:~/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr$ mcumgr --conntype serial --connstring "/dev/ttyACM0,baud=115200" echo hello

What is your full build command?
Is there more than one ttyACM in a system and are you sure that the right one is in use?

[de-nordic]

Have you been able to access shell via putty?

[CEmir10]

Yes, i am able to access ACM0 via putty.

Now it works for me with nrf42840, but now i switched to my board atsame70j19 and when i try to build it, it says me error __device_dts_ord_DT_CHOSEN_zephyr_uart_mcumgr_ORD undeclared

[de-nordic]

Now it works for me with nrf42840

What was the problem?

__device_dts_ord_DT_CHOSEN_zephyr_uart_mcumgr_ORD

Seems you do not have the zephyr,uart-mcumgr = &<uart label> in you DTS. Look at the boards/arm/nrf52840dk_nrf52840/nrf52840dk_nrf52840.dts

[CEmir10]

I just had to add two more files to build overlay-serial.conf and overlay-shell-mgmt.conf and then it works fine.
I added already in device tree zephyr,uart-mcumgr = &uart0, but it does not work

If you try to build it for sam_e70_xplained you will get same error, but only if you enable serial, without enabling serial you can build it

I have looked at the boards/arm/sam_e70_xplained/sam_e70_xplained-common.dtsi and it seems that only usart1 is available (defined) as uart device, are you selecting the right device with the "chosen" thing?

[CEmir10]

On my board atsame70j19 i have only uart0, i can use it as console, but as i said if i MCU_BOOT_SERIAL=y and try to build it i jave an error

The mcuboot serial thing is for mcuboot not mcumgr library. It allows you to update application slot from mcuboot.
I think that we are mixing problems here.

[CEmir10]

yes i know. this is a part of device tree of my custom board / {
aliases {
i2c-0 = &twihs0;
i2c-1 = &twihs1;
i2c-2 = &twihs2;
led0 = &green_led;
sw0 = &sw0_user_button;
can0 = &can_silent;
};

chosen {
	zephyr,console = &uart0;
	zephyr,shell-uart = &uart0;
	zephyr,uart-mcumgr = &uart0;
	zephyr,sram = &sram0;
	zephyr,flash = &flash0;
	zephyr,code-partition = &slot0_partition;
	zephyr,canbus = &can0;
};

Whatever other board i try to build i get same error. Only Nrf boards work.
