[Om-beagle-panda-hybrid] [OM-Beagle-Hybrid] makesd script

[Joerg Eesmann]

Hello there,
yesterday I got my beagle hybrid to work. Here are my results:

in my PC the SD is /dev/mmcblk0, so I had to do some adjustments to the
makesd-script. The script that worked for me is attached.
The basic script works for device which are like /dev/sdb, so that you
only attach 1 or 2 to get the name of the partitions. In my case I had
to attach p1 and p2. Setting the device name to /dev/mmcblk0p did not
help either because some command like fdisk are using the pure device
name and fail on /dev/mmcblk0p.
The attached script it worked for me.
The calibration did not start automatically, so I had to start
ts_calibrate manually and restarted.
Furthermore during postinst a file named /etc/rts.conf will be copied to
ts.conf.cfg, and later it will be copied back, this file did not exist
in my case.
But... it is working, and it is fast.
