Test
How long does it take to reflash? To test, surround a copy-nand command with timing markers, like this:
ok t-sec( copy-nand u:\32014o0.img )t-sec
The result will be on the line above the ok prompt when it is done, e.g. 403S, which is 403 seconds. Send me the serial number, file name, and time in seconds.
Notes
- erase time is included in elapsed time,
Automating
