L5.4.47_2.2.0_MX8MQ SSH problem

[brsmnc]

Hi, I have an IMX8M EVK board. 

I want to build and run a basic hello world application on target. My host machine is win10. I tried visualgdb with visual studio 2019 but smarttty gives "LIBSSH2 returned LIBSSH2_ERROR_KEX_FAILURE" error.

I also tried ARM Development Studio but this time I'm getting error "Failed to connect sshd on [IP Addr]:22 Algorithm negotiation fail" when trying to connect 

But I can connect with putty and mobaxterm using SSH.

Do you have an idea? What should I do?

Hi Weidong,

Wow, building OS for printing hello : ) Currently I'm trying to get used to Yocto. Is there any ready to build packages ( ie L5.4.47) on somewhere like git servers for IMX8MQ EVK board?

Thank you.

Hi brsmnc,

    You can try to compile Linux image for i.MX8MQ with Yocto, and add corresponding packages to local.conf like below:

You can add these packages to file build/conf/local.conf as

.......

IMAGE_INSTALL_append += " packagegroup-core-ssh-openssh openssh-sftp-server "

......

above lines will make linux image  support ssh.

Have a nice day!

B.R,

Weidong

Hi again,

I tried that but bitbake failed. I think openssh and dropbear are conflicted.

The following packages have unmet dependencies:
packagegroup-core-ssh-dropbear : Depends: dropbear but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

How can I resolve that?

I removed the "...  ssh-server-dropbear \ .." from the imx-image-multimedia.bb file and it works with openssh on target now. Thanks.
