[bmarkus]

Team Tiny Core is proud to announce immediate availability of the second beta release of the piCore-8.0 edition.

With this release kernel is frozen, it will be used in final version (except really serious issue found).

- kernel updated to 4.4.15
- firmware updated to 20160715
- MicroPython updated to 1.8.2-19


8.0beta3

- kernel updated to 4.4.14
- firmware updated to 20160626
- MicroPython updated to 1.8.1-90
- added ZBUD=y to kernel config
- on-board audio enabled by default
- VC I2C disabled by default
- serial console works on RPi3, using /dev/ttyS0, all other boards /dev/ttyAMA0
- serial console terminal emulation change from VT100 to linux


8.0beta2

- kernel updated to 4.4.13
- e2fsprogs updated to 1.43.1
- MicroPython updated
- RPi firmware updated to 20160613


8.0beta1

- kernel 4.4.11
- glibc 2.23
- BusyBox 1.24.2
- util-linux 2.28
- e2fsprogs 1.43

TC scripts also updated to latest common base. Except ncurses which doesn't build properly all packages in the repo updated and rebuilt using the new toolchain, not just copied over from 6.x/7.x repos. Dependencies revised, may be different to previous versions. It means limited number of packages in the repo, e.g. Xorg and graphical stuff are missing.

Only one SD card image available, it works on all RPi boards. Download location:

Please try it and share your experience, bugs found, etc.

Couple of systems upgraded PI3, B.   No issues so far.

Still no GUI available ...
I have few questions and I'm sorry I don't understand much even after reading the book for TinyCore.
My Raspberry Pi is 3B.
But I think that is armv7 yet the test versions being built are under armv6. To me its a huge deal to just know if builts for armv7 are not built because they are the same as armv6 or not? If they are not the same in source code... then whats the difference?

Other question is when I download and then of course make space for the second partition, as ext4 why is this second partition needed? would it not be better to just extend the fat partition instead? Also I know that the fat partition is loaded into ram and then no changes can be made unless you tell it not to load into ram or you mount it and then make changes. How can I make it not load into ram? is it a boot code ? or what should I do? I couldn't figure it out after reading the book.

[bmarkus]

Test versions work on ALL RPi boards. It is stated in release announcement. Read it!

FAT partition is not loaded to RAM.

Do not use the FAT partition (/dev/mmcblk0p1) other than boot. Keep as it is except customizing command line and config. It is not Linux-friendly and not a journaling file system.

Hi,

Is there a complete list of TCZs currently available for piCore 8 with brief descriptions? I'm looking for an image display utility such as fbi or qiv and I tried searching with TCE for keywords such as image/picture/viewer and only found libraries but not utilities.

Thanks,

[Juanito]

You mean like:

http://tinycorelinux.net/8.x/armv6/tcz/
http://tinycorelinux.net/8.x/armv7/tcz/

[tohox]

Yes. Well, almost... I had already found those lists but unless you are already familiar with the extension names and know what they do it can be difficult finding what you need. I assume that using the keyword option in TCE searches through all the module descriptions as opposed to the search option which only looks at the titles. Correct?

So if don't find any extensions whose name I already know through the search option and don't find anything related to relevant words through the keyword option then it is safe to assume that there is no such extension available as yet?

Thanks,

[curaga]

The tags option searches through tags.db.gz, so if no viewers come up, there either are none, or they don't have that as a tag.

Hi Bela.

I have a problem with the Hifiberry DAC+ I2S DAC now. It simply isn't detected. Other I2S DACs are working fine (like the IQaudIO DAC).

Do you have an idea of what is going on.
I will try to go back to previous piCore versions to spot where it was working.

so in piCore version7 the Hifiberry DAC is found but in version8 it is not found.
In both tests alsa.tcz is installed via tce command.

Hi sbp
From the version that works:

Code: [Select]

[   15.596562] snd-rpi-hifiberry-dacplus sound: pcm512x-hifi <-> 20203000.i2s mapping ok

Is it possible  i2s  got disabled in the newer versions?

[bmarkus]

Hi Steen

I don't have such board so can't test. Kernel config related to sound in 8.0 is the same as Raspbian. If it Works there look for differences in config.txt

Next week will be beta5 with 4.4.17 kernel but expect no deifference.

Béla

[Paul_123]

Bela,

I don't have the boards to test either, and not sure yet if it will fix the problem.   But the alsa-modules-KERNEL extensions are missing the module.
