piCore-7.0alpha1

[bmarkus]

Team Tiny Core is pleased to announce the availability of piCore-7.0alpha1, the Raspberry Pi port of Tiny Core Linux (TC). Base system components updated to the latest upstream versions:

* kernel 4.1.4
* glibc 2.22
* BusyBox 1.23.2
* gcc 5.2.0
* e2fsprog 1.42.13
* util-linux 2.26.2

This version supports the RPi CM (Compute Module).

As a new feature Micro Python added to base. It is a small footprint version of Python 3.4 developed for embedded systems, ideal for scripting tools replacing shell.

Download links:

http://tinycorelinux.net/7.x/armv7/test_releases/ - for RPi2
http://tinycorelinux.net/7.x/armv6/test_releases/ - for all other boards

Only the SSH version is offered. If you want GUI, install TC.tcz from the repo. To get the base system with cloud mode, no persistent storage just delete the second partition, /dev/mmcblk0p2 on the SD card.

To enable special devices and interfaces check config.txt file and read https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README

The final notice, don't forget to expand /dev/mmcblk0p2 before adding extensions, as described in README.

Hi Bela.

I'm testing the RPI2 version at the moment.

I have great sound coming from the analog onboard audio card, and USB DAC and the IQAudiO I2S audio DAC - so that is great.

Regards
Steen

I will check the wifi later.

PS: the problem we had with expanding the partition is gone in this version.

Hi Bela

I noticed one strange issue.

In piCorePlayer we have a script running from bootlocal.sh which set all the stuff we need for our audio player.

I don't know how to explain but it newer fully disappears after booting so we newer come directly to the prompt. It always needs a physical press on the "Enter" button - and then we are at the tc promt.
It has always been like this - and it is still like this.

But with the new version, there is a problem that now I can't reboot as long at our script is not terminated by an "Enter" press.

It doesn't matter how I try - via SSH and do a "sudo reboot" it wont reboot.
We use HTTPD as a web server and we have a reboot button on one of the piCorePlayer web-pages. It wont reboot.

But if I then press enter on the attached keyboard so that our boot-script terminates it reboots immediately (so it have received the reboot commands but they are not executed before we get to the terminal prompt).

It has not been like this before. Here we were able to reboot even though our script run from the bootlocal.sh file behaved just like it does now.

So what to do?

Hi sbp
Is the last line of your script missing a carriage return?

[sbp]

Hi Rich

This is our bootlocal.sh file:

Code: [Select]

#!/bin/sh
# put other system startup commands here

GREEN="$(echo -e '\033[1;32m')"

echo
echo "${GREEN}Running bootlocal.sh..."
/home/tc/www/cgi-bin/do_rebootstuff.sh


And this is our script called do_rebootstuff.sh

Hi sbp
Just a guess on my part, but it might be because bootlocal runs in the background. What happens if you call it from bootsync
and don't background it?

[sbp]

SORRY - my bad.

I accidentally added the bootcode pause to the cmdline in the new version I tested.
So naturally it would wait for me - stupid me.

Regards
Steen

Hi tested three different wifi dongles all working fine:

a D-Link DWA-131 using this:
r8712u: Loading firmware from "rtlwifi/rtl8712u.bin"

a Ralink dongle using
rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin

a TP-link (Realtek) dongle using:
usbcore: registered new interface driver r8188eu

All working fine with no problems.

Hi Béla,

great job, seems that it works well.
Please share the .config file for make the kernel and kernel modules. I need some modules like w1, rtc, net-usb, raspidac3 ...

Regards,

Jan

[gavinmc42]

Don't know where you find the time Bela.
Seems to work fine so far.

Had a look at Windows 10 IoT and Snappy for Pi, compared to piCore they are bloatware.

Been trying to use the new micropython, just because shell scripting is so yesterday:)
I think the micropython-lib needs to be tcz'ed for anyone used to python 2/3 coding.

Trying now to see if the method I used for gpio tweaking via shell script can be done by micropython.
ie read/write to files /sys/class/gpio/...
Might be easiest to just use the python interface to the pigpio daemon.
http://abyz.co.uk/rpi/pigpio/index.html

Micropython has some interesting links like this one
http://openmv.io/
Run Openmv on a Raspberry Pi?

@gavinmc42

Thanks for the feedback. I'm using 7.0alpha1 regularly and it works fine.

Do not know Snappy. Tried WINDOS10 IoT, it is different kind of animal. Requires minimum 8GB SD card. Has nice screens, but my ordinary USB keyboard doesn't work, WiFi stick not recognised, etc. Well, it is written on the MS WEB page, no suprise. First version, hopefully they will fix it. Good question, how much apps will be written, we will see. Good point you can work in Python, not only in C# which is not bad anyhow. For sure there are .NET anc C# guys happy to use their skills on RPi2.

MicroPython is a nice program. The os module is already part of piCore base, so you can execute external programs with os.system(), have common file system operations, etc. Will add other modules in tcz packages later.

If you want to submit pigpio.tcz you are welcome
