up an HDMI-to-VGA adapter for the monitor I have for this project
You have an analog only monitor on the RPi.
I have an HDMI to VGA adapter. More on that below.
dd bs=1M if=/home/geoff/Downloads/RAT_RC1/RAT_RC1.img of=/dev/sdb1 3000+0 records in 3000+0 records out 3145728000 bytes (3.1 GB) copied, 239.58 s, 13.1 MB/s
Should be /dev/sdb if that's the location of the SDcard. /dev/sdb1 is
the 1st
partition on there, and that image needs to be on the boot block.
That's exactly what happened. I re-wrote the SD card, leaving off the partition, and booted the Rpi3 and was successful - to a point. Activity light, there was text flowing on the screen, the ethernet port is lit, there is currently both the red power LED lit, as well as the green ACT LED lit, but the video went away. :-/
I'd try the sdcard and find a HDMI/DVI monitor, or just plug it into your
tv :) I don't have an HDMI monitor/tv in the shack. --- 73 = Best Regards, -Geoff/W5OMR
