Now power off your board c.Hold the update button labeled SD (the one by itself) to boot off the sdcard. d. Restart (RST button) or power up (while still pushing SD button). e. Flashing can take some minutes. 8. blue leds in "pong" pattern. waited till all 4 are solid blue. 9. waited a bit more till all lights off. 10. removed sd card. 11. powered back up by pushing "pow" button 12. followed instructions in YouTube video from Arrow. a. set up and tested wifi b. sudo apt-get update c reboot using "sudo shutdown -r now" c. made new directory "sandbox" d. cd into "debian@beaglebone/sandbox" e. in git found librobotcontrol. cloned. got address. did git clone "address" 13. all files appear to be there. 14. did sudo dpkg-reconfigure librobotcontrol and sudo apt update && sudo apt upgrade librobotcontrol 14. tried cc rc_blink.c. got same errors about undefined references.
