Raspberry Pi / Re: piCore 16.0 and Raspi Touchscreen.

Hmmm, should be tcz, not gz. Still won't install with 65 checksums not matching.

Code: [Select]

tce-fetch.sh touchscreen-KERNEL gets a Not Found error. Same for

Code: [Select]

tce-fetch.sh touchscreen-KERNEL.gzOr maybe you meant for me to insert the kernel version.

Code: [Select]

tce-fetch.sh touchscreen-6.12.25-piCore-v8.gz gets the same Not Found error.

tce Search "touchscreen" finds 4 citations, 2 that match the 6.12.25 part of my kernel. Neither will load  (error: checksums did not match), so apparently they don't match.

uname yields:

Code: [Select]

tc@box:~$ uname -rsv
Linux 6.12.25-piCore-v8 #5 SMP PREEMPT Sat Apr 26 13:42:06 EDT 2025
My application makes direct reads and writes to the Xorg server. No window manager, no toolkit. The app writes to the screen without a problem, it's only that Xorg doesn't see the touchscreen. It finds a mouse OK.

I enabled the vc4-kms-v3d line in config.txt.

Have you tried to install pcre2 ?

tce-load -wi pcre2.tcz

It looks like the dep file needs adjusting - does loading pcre21042 fix things?

General TC Talk / Serial Port

« Last post by MTCAT on February 10, 2026, 12:01:07 PM »

Hi everyone,

I bought a temperature sensor which when setup ahead of time on another machine, under the application of the next power up, acts as a virtual com port and simply outputs temperature readings in an ascii character string at 9600 bps.

It seems to work on my old TC 3.8.4 (kernel 2.6.33) except as soon as I try to look at the output of the port with;

Code: [Select]

cat /dev/ttyACM0

or with;

Code: [Select]

microcom -s 9600 /dev/ttyACM0

Everything seems okay, but when i Ctrl-C (in case of cat) or Ctrl-X (in case of microcom) my system returns in a very strange state; I do get the command prompt back but typing

Code: [Select]

ls

Returns nothing but an "Input/Output" error, and it seems that my filesystem is completely gone!!??

I am able to

Code: [Select]

sudo poweroff

And turn off gracefully (I hope) but I wonder if anyone has encountered this before and knows a possible solution? I also tried to install a python program "grabserial" but after installation of pyserial library, the program "grabserial" is not working at all, error codes of various types.

And strangely, after exiting "cat" or "microcom"  typing  "dmesg" doesn't show anything telling regarding this.

I did test the sensor on an even older distribution (2.6.21) on as ASUS EEE laptop and it seems to fully work in the sense that I can "cat /dev/ttyACM0" and I see the output strings just fine, and hitting "Ctrl-C" to exit "cat" the system is back to normal, no "lost" filesystem.

Any ideas as to what's going on with my TC 3.8.4 setup regarding this?

Thanks,

David

Hi,
git seems to not work in TinyCore 17 x86 (it did before in 16.2). I installed TinyCore from the CorePlus-current ISO from http://tinycorelinux.net/17.x/x86/release/CorePlus-current.iso
I installed git using the Apps menu.
This is the error I get:

Code: [Select]

tc@box:~$ git
git: error while loading shared libraries: libpcre2-8.so.0: cannot open shared object file: No such file or directory
Installed extensions:

• python3.14 (I really like it by the way)
• tk9.0
• tk8.6
• Xdialog
• squashfs-tools
• dillo
• git

I ran update-everything after installation, there were no updates

General TC Talk / Re: New Boot Drive 16 GB -> 4 GB

« Last post by Rich on February 09, 2026, 11:32:45 PM »

Hi MTCAT

Not sure how the 4GB pen drive would have ext4 with 64 bit compression when the source drive apparently does not ...

It doesn't. The  dd  command duplicates what and where it finds on device A on device B.

TCE Bugs / Re: Segmentation fault in Xdialog

« Last post by Rich on February 09, 2026, 11:24:05 PM »

Hi karl52
I think I've isolated the what, but not the why.

I booted up a CD containing TinyCorePure64-16.2.iso.
I added the boot codes  base norestore  so it would not try to
access any  tce  directories or  mydata.tgz  files on my system.

I then used Apps to  Download + Load  Xdialog.tcz.

I was able to reproduce your segfault.

Since the error appears to be font related, I looked at the X11 font related
directories of the working systems and installed extensions to make the
failing system match. It did not solve the issue.

I then rebooted to start over. This time I exited to the system prompt and:

Code: [Select]

tce-load -wil Xorg-7.7 XdialogXdialog worked correctly.

I believe Xfbdev may be the issue. It's possible one of its options might
solve the issue. You can list them like this:

Code: [Select]

Xfbdev - help
These look like they might be useful:

Code: [Select]

-fc string             cursor font
-fn string             default font name
-fp string             default font pathThough I have no idea what to set them to.
