(1/5) > >>

bmarkus:
First test release of piCore v5.2 available.

http://tinycorelinux.net/5.x/armv6/release_candidates/

Change log:
* rebuildfstab: do not replace fstab entries for a device that does not have "Added by TC" on the line (thanks to Gerald Clark)
* init: increase the default inode count
* ondemand: don't list extensions under subdirs in onboot maintenance
* busybox updated to 1.22.1 and split suid/nosuid for better security
* ldd: Added quotes for binaries with spaces in their names
* /etc/services: modified to suit rpcbind rather than portmap
* tc-functions: Removed the getpasswd stars to allow backspace to work
* added accelerated arm-mem library to spead-up memcmp, memcpy, memmove & memset
* updated Raspberry Pi firmware

Hi bmarkus
I will test the new version soon.

What kernel are you using. 
The new 3.12.9 has some interesting  development,  in the i2s area,  also the new firmware has better usb audio handling.

Kernel is not updated, see list of changes in the first post. Goal is to have 5.2 changes from x86 adapted + arm-mem library.

Kernel is changing too often, I do not like to follow it continously with all consequencies in every 1-2 weeks. RedHat/CentOS is on 2.6.32 :) When 3.12.9 would be finished maybe 3.14.0 will be there or, 3.13.3? Why not 3.13.x?

Can you explain a bit new features?

Hi Belá

As you know I very interested in the audio part of raspberry and microcore, so therefore my focus might be too narrow.

However, some of the interesting changes are:

Firmware: https://github.com/raspberrypi/linux/issues/320 . this issue describes crackling noise in the HDMI output, but also via an USB_DAC. This is a problem often encountered when using raspberry and an external USB-DAC. However, this was added to the firmware 2 days ago.

Kernel: The I2S connection is very interesting for an audio player build on the raspberry - for the exact reasons mentioned above. By using I2S we don't see the same cracks and pops in the audio as we see using USB-DACs.
The current kernel in microcore supports the HiFiBerry I2S DAC (and also other DACs) with great results. But the new kernel 3.12.9 supports a pure digital I2S HiFiBerry card http://www.hifiberry.com/hbdigi which will give our raspberry a digital audio output.
https://github.com/raspberrypi/linux/commit/a76cc555cbac2a2136a7a0b4078381704a57d59d

By the way I'm not in any way connected with the company selling HiFiBerry audio cards, I just like the cards, and they are at the moment the only available I2S audio cards for our raspberry.
 
I would like to support the addition of digital out (S/PDIF or Toslink) in the piCorePlayer, therefore I had started building the newer kernel for microcore, but then I read this thread and thought that you might be working on the same.

Hi Steen

I like your player and I delayed 5.1 to make the I2S DAC support working correctly :) Problem is that kernel is changing too fast and also as you remember around 3.12.2---5 there were broken unworking releases. This 3.12.7 is a stable version and I will replace kernel later a bit when more new features accumulated. Of course custom kernels for appliances like your are welcome as well as feedback, comments, etc.

5.2 script base looks OK, I'm using 5.2alpha1. What is happening is a repo cleanup specially to eliminate use of libiconv.tcz and at the same time moving accelared arm-mem function to eglibc-2.18 source tree as a new port to gain performance by default not with so overwriting as it is now.

Kernel 3.13.y is too young, it is not consider at the moment.
