1 | time-sync is a utility to sync the time with any Rockbox target that runs the | ||
2 | software USB stack. | ||
3 | |||
4 | It was originally take from libgpod and stripped of unnecessary code. | ||
5 | |||
6 | http://gtkpod.git.sourceforge.net/git/gitweb.cgi?p=gtkpod/libgpod | ||
7 | |||
8 | To compile and install, just run: | ||
9 | make | ||
10 | make install | ||
11 | |||
12 | Example run: | ||
13 | mcuelenaere@wim2160:~/rockbox/utils/time-sync$ sudo time-sync /dev/sdb1 | ||
14 | Data Payload: 07 da 00 14 04 0c 30 2b 00 00 00 00 | ||
15 | Write buffer cmd: 3b 01 00 0c 00 00 00 00 0c 00 | ||
16 | Time was synced! | ||
17 | |||
18 | Example udev rule (for Onda VX747): | ||
19 | # automatically adjust my Rockboxed DAP RTC | ||
