Hi,
How can I connect my imx8m Mini board with winscp if I don't have the server's ip?
You can boot up your board first, and then see your board IP address. Then you can try the following thread https://community.nxp.com/message/1126058 check to make the winscp work.
I have the image obtained from here: L4.14.98_2.0.0_ga_images_MX8MMEVK
It has dropbear ssh, but it is enabled, how do I know that ssh is running? The IP is in the same subnet.
