Touchscreen Tiny210 misaligned in Android

I'm using Tiny210V2 with 7" LCD. (ft5x0x)
The touchscreen works properly when installing WINCE6.0 and after running
"Stylus" program.
On Android, I just cannot get it to calibrate or run properly:
Using cmd line skipcali=yes and ctp=3,
the touchscreen works but it's like the coordinates are "mirrored":
1. A slanted swipe from bottom left to top right, writes pattern from top
right to bottom left.
2. A swipe from bottom right to top left, writes a pattern from bottom
right to top left but quite offset to the left of the screen.
3. A horizontal swipe writes a vertical line and a vertical swipe a
horizontal one.
(3) makes it look like the screen rotation is out, but enabling screen rot
and rotating 90 degrees no avail either.

Anyone know what is going on here?
I'm kinda stuck, uname -a gives :
Linux FriendlyARM 3.0.8-FriendlyARM #1 PREEMPT Mon Feb 24 18:33:21 HKT 2014
armv7l GNU/Linux.

grep for "pointercal" file gives nothing.

Update : Resolved!
I have no idea why it previously did not work (tried several times) but
CTP=2 fixes it;
[XXXXX] ft5x0x_ts 2-0038: FocalTech ft5x0x 4.3 Touchscreen initialized.
Explains why rotation was wrong, size was wrong :-)
