Edison Arduino에서 갑자기 스케치가 업로드 안될때.

#mv the downloaded file to /sketch/sketch.elf
Moving downloaded file to /sketch/sketch.elf on target
target_download_name="${host_file_name##*/}"
echo "Moving downloaded file to /sketch/sketch.elf on target"
#$fixed_path/lsz.exe --escape -c "cp sketch /sketch/sketch.elf" <> $tty_port_id 1>&0
$fixed_path/lsz.exe --escape -c "mv $target_download_name /sketch/sketch.elf; chmod +x /sketch/sketch.elf" <> $tty_port_id 1>&0
Retry 0: Got TIMEOUT
Retry 0: Got ZCAN

Transfer incomplete

You're right Doug, after deleted all contents in from /var/log/journal directory the sketch was correctly uploaded.

Thanks a lot.
