right here's a few little files: http://rhombus-tech.net/community_ideas/kde_tablet/csivoltages.py http://rhombus-tech.net/community_ideas/kde_tablet/axp209.py http://rhombus-tech.net/community_ideas/kde_tablet/gpio_up.sh in case anyone ever needs to program the AXP209 from userspace, the axp209.py (GPLv2, taken from u-boot, thanks to henrik, cut/paste conversion from c to python) file is capable of setting the LDO2, LDO3 and LDO4 voltages. the gpio_up.sh is a little script which pulls the relevant GPIO pins for BOOT0 and RESET on the STM32F. l.

3D acceleration working with Ubuntu 13.04 for EOMA68-A20 (and Cubieboard2)

3D acceleration working with Ubuntu 13.04 for EOMA68-A20 (and Cubieboard2): http://www.gplsquared.com/eoma_boot/eoma_boot.html#Ubunt_13_04_3D Functions more and more like a real PC now. Kicad also got installed and it is reasonably usable. So use that to design your next EOMA application PCBs :) Also installed were xfce4, lxde and openbox window managers. Gambas installed from sources. The sound works through jack socket (hdmi sound - nothing as yet although it is known to work through booting up Android), and espeak works. So you could send it commands through serial port for example software, let gambas serial port program read the text and then the machine can be made talk back by gambas calling espeak. : I used it for the embedded work - instead of reading reams of logs, it puts important data out as text embedded inside <s>..things to say...</s> brackets and I filter for that with a gambas program and get the most relevant points read back out. NICE!!! When you first log in, a 3D animation runs if its all working.

Specifics of EOMA gpio
by joem 10 Oct '13

10 Oct '13

Hi Luke or anyone, Need to know specific commands to turn on/off EOMA gpio lines for some testing. Is there documentation somewhere? If not, create a web page, and let me know where and list of lines that can be controlled, and i check it and get it documented etc....

flying squirrel weirdness on the I2C bus
by luke.leighton 09 Oct '13

09 Oct '13

ahh.... something really weird going on with the flying squirrel i2c addressing. i'm running i2cdetect and it's showing up 0x34 for the AXP209 I2C address instead of 0x68, and so on. i _thought_ i got the address for the I2C EEPROM right, from the datasheet (0xA2) - but it seems that it's been shifted by one bit (0x51) as well. help! i have no idea what's going on here! l.

Possible GPU?
by Lauri Kasanen 09 Oct '13

09 Oct '13

Hi, I was wondering if you'd heard about Bruno's open GPU that's about to go kickstarter, and what you think of it. They want to open the IP from Number Nine, in FPGA form. It has both 2d and fixed-function GL parts, separable from each other if only 2d is needed. I don't know of the exact specs yet, and clearly making it an ASIC would be costly, but it's still an interesting proposition. - Lauri [1] http://en.wikipedia.org/wiki/Number_Nine_Visual_Technology [2] http://phoronix.com/forums/showthread.php?82356-Would-A-Kickstarter-Open-So…

http://www.theverge.com/2013/9/10/4715514/intel-quark-internet-of-things-we… Intel's new "Quark" (might be the X1000) chip, which runs an x86 architecture at 400 MHz, somewhere between .4 and 1.3 watts.

http://rhombus-tech.net/community_ideas/kde_tablet/news/ i got the ADC operational. also as anyone on the #arm-netbooks irc will notice i've done a reorganisation of the kde tablet news page, so each entry has its own page that is available for discussion. for example here: http://rhombus-tech.net/community_ideas/kde_tablet/news/2nd_revision_adc_op… also there's an RSS feed - i liked the idea and threw it out there: http://rhombus-tech.net/community_ideas/kde_tablet/news/index.rss l.

Chinese SoC vendor striving for world domination? Show your GPL loyalty page or get out of business!
by Paul Sokolovsky 06 Oct '13

06 Oct '13

Hello, I don't know if other folks noticed that already, but by now almost all Chinese ARM SoC vendors (targetting mass consumer market) put up some kind of "GPL/FOSS loyalty" page - and sources. I specifically call that "GPL loyalty" because as we know, there's some road ahead (maybe long) before it's "GPL compliance". Good news that some go beyond just GPL and provide Android sources, etc. It's yet to be seen how actually that useful technically as of now, but the talk about the outlook change. I'm sure that some of the vendors below did that because others did it. So, it looks like it gets self-sustaining, as put in subj: people come to you, and in quick chit-chat ask where's you GPL page, and if you say "nowhere", you get that strange look and people move to other booths, because Allwinner, Rockchip and everyone has it, and if you don't get that simple license thing, how you can actually hack on kernel and produce value? The list is: Telechips https://www.telechips.com/technical_support/kor/opensource/opensource_list.… Rockhip http://git.linux-rockchip.org/public/ Allwinner http://www.allwinnertech.com/en/awt/news/2013-04-23.html Amlogic http://openlinux.amlogic.com/ VIA/WondermediaLinux on small ARM machines <arm-netbook(a)lists.phcomp.co.uk> http://apc.io/library/ Rest of rant is here: http://pfalcon-oe.blogspot.com/2013/10/growing-gplfoss-loyalty-among-chines… -- Best regards, Paul mailto:pmiscml@gmail.com
