Re: [SlimDevices: Unix] piCoPlayer = Squeezelite on Microcore linux. .An embedded OS in RAM with Squeezelite
Hi Steen, Greg, I did an insitu upgrade of 1.19 to 1.19L. The upgrade worked and after some 40 seconds the music resumed to play again. Looking at dmesg output there is still that message about the filesystems not correctly unmounted. Is this because of 1.19 having this issue and the insitu upgrade does not fix this? Wil it be gone when I download the 1.19L image and write it to the SD card myself instead of the insitu? Code: [ 14.346070] FAT-fs (mmcblk0p1): Volume was not properly unmounted.

The raspberry (piCorePlayer) will have a new IP-address for the wifi connection. I use advanced-IP scanner (http://www.advanced-ip-scanner.com/) to find my piCorePlayer on my network. However, you might be able to find the address if you follow these instructions: - Reboot the piCorePlayer with LAN cable attached. - Set-up wifi on the web-page. - reboot piCorePlayer - SHH into the piCorePlayer - write ifconfig - and now you should be able to see both the IP-address for the LAN connection and for the Wifi connection. - Remove LAN - Reboot (or pull the power) - Use the wifi IP-address you got Regards Steen piCorePlayer a small player for the Raspberry Pi in RAM.

Re: [SlimDevices: Unix] piCoPlayer = Squeezelite on Microcore linux. .An embedded OS in RAM with Squeezelite
Since early versions of piCoreplayer i am using my own scripts to stop all procesess which are not necessary for playing music few minutes after boot process - httpd, udevd, udhcpc, crond, dropbear. In this way Pi has more ressources for squeezelite and IMHO sound quality with a very good usb dac and very good hifi system is better. Would it be possible to built in one extra option for high end freaks into picoreplayer gui allowing to stop all unnecessary processess 5 or 10 minutes after booting, but only then, when there is no access to web gui ? In this way it will be possible to change configuration just after reboot and later all possible CPU/bus ressources could be available to squeezelite. In my scripts i am also unloading unused kernel modules and umounting unnecessary mounts, but greatest impact has stopping some unused services and tcpip optimization. I don't want to start a flame war about "bits are bits" and when it is working, than it is working, i just have a proposition to add some "high end approach" to this great piece of software :) Here is my script for Pi 2 whith usb dac (waveio+buffalo II) : # add at the end of /home/tc/www/cgi-bin/do_rebootstuff.sh # make backup with sudo filetool.sh -b sleep 600 # some tcpip optimizing sudo sysctl -w net.core.rmem_max=26214400 sudo sysctl -w net.core.wmem_max=26214400 sudo sysctl -w net.ipv4.tcp_rmem='4096 1048576 26214400' sudo sysctl -w net.ipv4.tcp_wmem='4096 1048576 26214400' sudo sysctl -w net.ipv4.tcp_mem='26214400 26214400 26214400' sudo sysctl -w net.ipv4.route.flush=1 sudo sysctl -w net.ipv4.tcp_no_metrics_save=1 sudo sysctl -w net.ipv4.tcp_moderate_rcvbuf=1 sudo sysctl -w net.ipv4.tcp_timestamps=0 sudo sysctl -w net.ipv4.tcp_sack=0 sudo sysctl -w net.ipv4.tcp_window_scaling=1 # unload unsused kernel modules sudo rmmod snd_bcm2835 snd_soc_pcm512x_i2c snd_soc_tas5713 i2c_bcm2708 spi_bcm2708 snd_soc_bcm2708_i2s sudo rmmod snd_soc_pcm512x regmap_i2c regmap_mmio snd_soc_core snd_pcm_dmaengine snd_compress sleep 3 # stop services sudo /usr/local/etc/init.d/httpd stop sudo kill -9 $(pidof udevd) sudo kill -9 $(pidof udhcpc) sudo kill -9 $(pidof crond) sudo umount /dev/loop1 sudo umount /dev/loop5 sudo killall dropbear sudo umount /dev/loop0 sudo sh -c "sync; echo 3 > /proc/sys/vm/drop_caches" # end praganj's Profile: http://forums.slimdevices.com/member.php?userid=41091 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] piCoPlayer = Squeezelite on Microcore linux. .An embedded OS in RAM with Squeezelite
Hi, I use fing to see whats going on in my network. After connecting LAN and go to Web config I setup wifi. At console I make an iwconfig and ifconfig. I see that wifi is established and wifi gets an IP address. I make a cat to /etc/wpa_supplicant.conf and see here my wifi configuration. After reboot without lan the /etc/wpa_supplicant.conf is empty* and wifi doesn't work. Than I connect LAN again and wait until eth0 gets an IP. Than I start the web config page, go to wifi, wait until available wifi networks are shown, configure my wifi again and press safe. After a few seconds wlan is online and gets an IP. I see that with ifconfig an iwconfig. >From that point I can start a ssh and web config session over wlan IP. Now /etc/wpa_supplicant.conf contains again my configuration. But this is only working if I have also a LAN connection. Without LAN nothing is working.

Do you have a hidden SSID? Assume wifi setup is very simple if: - SD card is not corrupt. - USB wifi adaptor is supported by Raspberry Pi. - SSID is correct and valid. - Password is correct and valid. - SSID is not hidden. regards Greg Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

We have added the "User commands" feature on the tweaks page to give people hooks into the booting process. Here's is what I suggest. Place your commands into a script, clean.sh Comment out sleep 600, we will do that later. chmod 755 clean.sh Put the script into the /opt (or /home/tc) directory. Do a backup, "sudo filetool.sh -b" or just press a "Save" button on the web gui. In "User command #1" add: sleep 600; /opt/clean.sh & Hit the "Save" button. Reboot. For testing I suggest "sleep 60" it still gives you enough time to adjust things. regards Greg Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
