I have successfully ported functionality and code from the TS7390
to the TS8390+TS4700. I am very impressed with the performance of
the new boards.
In my old setup with the TS7390 the board took approximately 90 seconds
to boot, configure X windows system, configure the network, and start
my graphics application. This did not vary appreciably when booting
from internal flash or SD card.
I see much quicker boot times on the new board set, as I mentioned.
However, it is incredibly fast when booting from microSD card - approximately
20 seconds. What puzzles me is that when booting from
internal flash, it takes over twice as long, anywhere from 45 seconds
to 60 seconds. The variability seems to be how long it takes to mount
the internal flash 'big root.' I can live with this.
But why, discounting the mount time, does it actually take twice as
long to go through the booting motions? I think it actually just runs
slower in general when running from internal flash vs microSD.
I spent considerable time making sure the boot procedure is as close to
exactly the same as possible.
Anyone have any ideas?
