Just as a follow up...
I tried an old wheezy image I had:
bone-debian-7.11-console-armhf-2016-06-15-2gb.img.xz
That image is pretty bare bones so I had to install a number of packags.
Just for completeness these are what I installed:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install locales
$ sudo dpkg-reconfigure locales <- set the correct locale to avoid
other issues, I used en_US.UTF-8
$ sudo apt-get install git gcc g++ python libts-0.0-0 libts-bin
python-pygame
This image has an old kernel:
$ uname -a
Linux beaglebone 3.8.13-bone80 #1 SMP Wed Jun 15 17:03:55 UTC 2016 armv7l
GNU/Linux
So, now figure out what the touchscreen device node is:
$ ls /dev/input/by-path/ -la | grep tsc
lrwxrwxrwx 1 root root 9 Jan 1 2000 platform-tsc-event -> ../event1
Now calibrate and test the touchscreen:
$ sudo TSLIB_TSDEVICE=/dev/input/event1 ts_calibrate
$ sudo TSLIB_TSDEVICE=/dev/input/event1 ts_test
Yeah! It appears to work (FYI, my screen is a 4DCAPE-70T).
I then tried this simple pygame python script:
$ cat test.py
#!/usr/bin/python
import pygame
import os
os.putenv('SDL_MOUSEDRV', 'TSLIB')
os.putenv('SDL_MOUSEDEV', '/dev/input/event1')
pygame.init()
screen = pygame.display.set_mode((800, 480))
done = False
while not done:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
elif event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
done = True
pygame.display.flip()
$ sudo ./test.py
Success! (At least with wheezy...)
Note, this was done without any editing of the /boot/uEnv.txt so there are
a number
of bone_capemgr issues in the dmesg output:

Also, one strange issue I had.
I previously updated the bootloader on the eMMC when I was testing with
Debian 9. In order
to get the BeagleBone to boot from the SD-Card I had to hold in the button
when it was powered
on. I never had to do this before.
This is the output of /opt/scripts/tools/versions.sh
$ cd /opt/scripts/tools
$ git pull
$ sudo ./version.sh | grep bootloader
bootloader:[microSD-(push-button)]:[/dev/mmcblk0]:[U-Boot
2016.03-00001-g148e520]
bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot
2018.01-rc3-00002-gb33224]
The next time I powered on the board I didn't have to hold the button.
Strange....
Regards,
Hartley
