How do I transfer the files from my Coral Dev Board to the SD card/ PC for training?

I have connected my coral device to my Windows laptop running UBUNTU 20.04 1)When I try to " scp file.tar.gz @: /home/, I get an error stating "ssh: connection to port 22: lost connection and sometimes refused connection". I tried to put my Mendel boards IP and host username, then it asked me for my password but then denied permission.

2)Now I wanted to try it using the SD card. So I formatted the SD card in ext4 format and mounted it using " sudo mount /dev/mmcblk1 /mnt. And I can access contents of the SD card.

Now my question is- how do I transfer contents(files and pics) from SD to the Coral board and vice-versa?

I'd appreciate a detailed answer please. If you know the answer to query 1) please mention or if you know the answer to both pls try to help.

Thank you.

  1. There are 2 ways to do this:
  • You can use mdt push or mdt pull to move file from and to the dev board. Refer to this doc: https://coral.ai/docs/dev-board/mdt/#mdt-commands
  • mdt should already creates a public key o n your host machine in ~/.config/mdt/keys/mdt.key, you can try ssh/scp using that key
ssh -i ~/.config/mdt/keys/mdt.key mendel@ip-addr

If that doesn't works, you can also make your own key:

ssh-keygen

Then copy your public key on to the dev board's ~/.ssh/authorized_keys and everything should works as normal ssh :)

  1. If you already mounted the sdcard, they it is as easy as copying or moving right?
cp /mnt/file-you-want /home/mendel/where-you-want
