TFTP Allow TFTP uploads from board to host
sudo vi /etc/default/tftpd-hpa
# TFTP PC -> board (make sure file in /var/lib/tftpboot has group read set, chmod +x xxxx) $ tftp -g -r desktop-shell.so 10.10.10.30 $ tftp 10.10.10.30 -c get devmem2 ### note, if devmem2 was built with Yocto, devmem2 will want to look in /lib64 for the libraries (so just copy the form /lib to /lib64, or make a symlink) $ tftp 10.10.10.30 -c put /tmp/link_reg.txt put localfile remotefile systemctl status tftpd-hpa.service
