RGB-to-MIPI
by Miguel Garcia 25 May '14

25 May '14

Hello everyone. Because EOMA-68 use RGB connection and most HD screens will use MIPI, I've been looking for a RGB-to-MIPI IC. Finally I found a RGB-to-MIPI IC, the part is SSD2828. At 1K pcs, the SSD2828 price is €4.20. The datasheet is not public, but if someone wants the datasheet, leave a message and I will send it by email. Do you know any better alternative? Thanks.

EOMA-68 and EOMA-CF
by Miguel Garcia 27 Apr '14

27 Apr '14

Hi, Any EOMA (68 or CF) will have more powerful hardware? Is Luke/Rhombus going to focus on EOMA-68 or on EOMA-CF? Is there a new EOMA-68 in the process with more powerful hardware (like Allwinner A80)? What will be the hardware of EOMA-CF? Thanks.

Re: [Arm-netbook] Another ARM new baby on the market
by Erix 24 Apr '14

Hi, for the 2 URL I gave earlier http://http://bananapi.org/# and http://http://www.lemaker.org/ it looks like they point to the same product. for buying it, there are plenty of vendors: http://www.alibaba.com/products/F0/banana_pi/----------------------50/3.html Thanks to Peter Green about his comment about Raspberry Pi's image: " You certainly aren't going to run an unmodified raspberry Pi image on the thing. It's a completely different SoC and will need a different kernel and bootloader. " It's clearly what I thought, but their synthaxes on their websites is deliberately not clear and maintains the ambiguity. Thanks to Peter. I saw somewhere on one of the 2 websites it's an Opensource project and they will "publish" sources for the images (SDCARDs) soon.. we'll see. The things that could be interessting it's examples of using the cameras port and the LVDS port and of course bootloader. so well, "nice.." website but not too much tecnical informations yet.. Bye bye for now Erix

Another ARM new baby on the market
by Erix 23 Apr '14

23 Apr '14

Hi everybody, what do you think of this new toy? http://www.lemaker.org/ I must admit their communication is a bit "ambigious", especially when they're talking about the Raspberry Pi compatibility.. if it's about pinout compatibility, I would say great. but on some of their sentences/phrases, we could almost think you could run the same "images" (sdcard) or binaries... from the Raspberry Pi on their "Banana Pi".... They're saying they support Debian, Ubuntu, Android (4.4) but they don't give URL where to find all of these distros.. Caracteristics: CPU A20 ARM® Cortex™-A7 Dual-Core GPU ARM Mali400MP2 Complies with OpenGL ES 2.0/1.1 Memory (SDRAM) 1GB DDR3 (shared with GPU) Onboard Storage SD (Max. 64GB) / MMC card slot UP to 2T on SATA disk Onboard Network 10/100/1000 Ethernet RJ45 (optional USB WIFI Dongle) Camera Input A CSI input connector allows for the connection of a designed camera module Sound Input Mic Video Outputs HDMI, CVBS , LVDS/RGB Audio Output 3.5 mm Jack and HDMI Power Source 5 volt via MicroUSB(DC In Only) and/or MicroUSB (OTG) USB 2.0 Ports 2 (direct from Allwinner A20 chip) Buttons Reset button: Next to MicroUSB connector Power button: Next to Reset button UBoot button (optional): Behind HDMI connector GPIO(2X13) pin: GPIO,UART,I2C bus,SPI bus with two chip selects, CAN bus,ADC,PWM,+3.3v,+5v,ground. LED Power Status LED (Red) Ethernet Status LED (Blue) User Define LED (Green) Remote IR good things: LAN 10/100/1000, Sata, HDMI, CVBS , LVDS/RGB, Camera... Why not? I saw the price around 57/60$ + delivery if I remember well. Will see. Bye bye for now Regards Erix

Warning: yahoo users postings might be lost
by Alain Williams 14 Apr '14

14 Apr '14

Summary: email sent by users with mailboxes held by yahoo may have their email disappear. This may be mail to a mail list (such as this one) their mail list postings may not be received by other yahoo users and also gmail users & a few others. Yahoo made changes without warning and have caused a huge on-line discussion by mailing list operators. Yahoo broke email lists. This is because at the start of the week Yahoo changed their DMARC settings to ask servers that receive a message with a yahoo.com email address in the From: line to reject it if it isn't properly signed by yahoo, which all messages they send will be. Basically, Yahoo has said that it users are not supposed to use any mailing list configured in the manner that they are often configured in. There are several possible workarounds, but none of them satisfactory. Discussion continues.
