Are you using PCP 4.1 ?
Are you using a waveshare 3.5inch 480 x 320 screen ?
If so, try this
Code:
--------------------
Set-up piCorePlayer to use the TFT screen
- using Win32DiskImager or Etcher write the piCorePlayer image that you
downloaded previously to your SD card.
- with your SD card still in the windows machine, use explorer to edit the
following files :
- cmdline.txt to match that shown in to current webpage instructions.
- config.txt to match that shown in to current webpage instructions.
- eject the SD card from the windows machine,
- place the SD card in the Raspberry Pi [Rpi], connect to Ethernet and power
on,
- run Advanced IP Scanner to identify the IP address used by the Rpi, now
loaded with the PiCorePlayer PCP image
- enter this address into your browser to bring up the PCP web interface,
- go to the Main Page and at the bottom select Beta mode,
- still on the Main Page select the Extensions button at the end of the
second section.
- select the piCorePlayer sourceforge repository and click the Set button
- select the appropriate touchscreen-... tcz extension from the repository
and click on the Load button.
- Check that the extension has loaded, and remember to hit the Reset button
before returning to the Main Page
- run WinSCP and log into PCP using the address obtained from Advanced IP
Scanner with username tc / password (piCore),
- using WinSCP, edit /opt/bootlocal.sh to include the following 2 lines,
modprobe flexfb width=320 height=480 regwidth=16
init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3
(line 1)
modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=16000000
gpios=reset:25,dc:24 (line 2)
- on PCP web interface Main Page select the Backup button from the second
section to backup the changes,
- on PCP web interface Main Page select the Reboot button from the first
section.
Following the reboot you should now have piCorePlayer output on your TFT
screen.
--------------------
If you still don't get output on the screen I would suggest the screen
is faulty - otherwise I don't know what else to suggest ...
Good Luck !
