Which is compatible with vim? USB to TTL Serial UART module


Thanks. I believe I also need to enable and start watchdog before reboot?

Related to main 4.17, is there a way to install that image into eMMC?


You don’t need to enable it.

Please refer to this


sorry, that instruction went over my head… command by command instructions would be helpful, just as you helped me before to update the kernels.

or if someone has already prepared a mainline image for vim1 eMMC that is able to rotate screen, then a link to that img would be enough too.


No image you can burn to eMMC directly now. You have to burn the image to SD card and boot from it, then execute some scripts to write it to eMMC.
