I also use a cheap chinese 3.5 TFT display with piCorePlayer 4.1.
For configuration I initially followed nowhinjing's excellent guide.
With my display, however, I found that the configuration can by
simplified to say
Code:
--------------------
dtoverlay=piscreen,speed=24000000,rotate=270
--------------------
in config.txt instead of dtoverlay=ads7846 ...
With the piscreen overlay I can skip the whole modprobe flexfb ... part
and leave /opt/bootlocal.sh unchanged.
I also found 'Greg's version'

for a jivelite.sh very useful. Firstly, you dont't get a million
jivelite.sh spawned (how did that '&' get in there anyway?). Secondly
you don't need to edit /home/tc/www/cgi-bin/pcp_startup.sh to replace
"awk '/FT5406 memory based driver/" with " awk '/ADS7846 Touchscreen/".
So another file you don't need to touch when upgrading pCP.
To switch the backlight I made a similar hack to the one 'referenced
here'
