I need to access U-boot on a uPC that I have that is running Debian. Typically I connect my uPC to a monitor and during the boot up sequence press any key on my keyboard and I am immediately entered into U-Boot. However, it would make my life easier if I could access U-Boot when I am connected via SSH using Putty.
When you reboot, the uPC when connected via SSH you never see the boot-up screen and that is why I am not sure if it is possible to access it with this type of connection.
I only need to run two commands while I am in U-Boot
setenv fdtfile imx7d-sbc-iot-imx7-can.dtb and then
saveenv. If there is a way I can enter these commands while connected via an SSH connection it would be very helpful.
If anyone has any insight on how I could go about doing this it would be very helpful.
