SSH on I.Mx8mmini

 I want to access the board from network so How to enable SSH on I.Mx8mmini.

You need to have ssh server installed and running on i.MX board to be able to access the board from PC .
So you need to install some ssh server (for example openssh-server).
And then you need to make sure that is is turned on as service with the command like "/etc/init.d/ssh status".

And of course you need to make sure that network configuration (hardware and routing) connects the PC and i.MX board.

Hi santhoshkumar‌

What settings have you made in yocto to enable ssh?

Thanks.

[santhosh2]

Add the below line in local.conf file to include SSH

#SSH
PACKAGE_EXCLUDE += " packagegroup-core-ssh-dropbear"
CORE_IMAGE_EXTRA_INSTALL += "openssh"

and then compile using bitbake

Regards

Hi santhoshkumar‌

I use the image imx-boot-imx8mmevk-sd.bin-flah_evk but it doesn't integrate openssh, do you know how to add it?

Openssh has compiled me but I don't have it in the picture.

Do you know how to do it?

regards

[inigovicentewal]

And how do you check that it is activated?

There has to be a ssh.service right?

Regards

I'm sorry for the delay.
I was told that it can be solved by commenting the default recipe layer added in fsl-image-validation-imx.bb
#ssh-server-dropbear
