HTH, Brian ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community Maybe it is my SD card that is broken. I tried Qi from QtMoko v38 and v44, installed QtMoko v38 and v44 on the SD, formatted the SD more than a time, I am able to mount it (both on my pc and my GTA02), read and write it, no errors shown by disk checks, but still no boot. Because Qi doesn't show any output I cannot say what is going on. Maybe I can use uboot but I don't know the parameters to select the SD. I use the following for the boot from NAND: >setenv bootargs ${bootargs_base} ${mtdparts} rootfstype=ubifs >ubi.mtd=6,2048 root=ubi0:om-gta02-rootfs; nand read.e 0x3200 >kernel 0x30; bootm 0x3200 How can I adapt it for the SD?

Hmm... I could not get what is the alternative to keyboard that slides out the "main case". If keyboard is not mechanically mounted with phone into single divice (e.g. if it is a separate "box" connected by a wire), it immediately gets a major usability hit - same as e.g. external bluetooth keyboard has. One can't keep phone AND keyboard in one hand while e.g. standing in crowded transport.

I think there's quite a lot of variation in modern phone keyboards. For example, some Blackberry phones have two alphanumeric characters per key, some phones have no number keys, some have an arrow key block and some don't, etc. Even within the confines of a basic qwerty keyboard, there seem to be many variations in layout; whether the rows are offset or aligned in a grid, whether there is a multi-row Enter key, the size of the space bar, etc. > > effects ease of typing, how the keyboard is integrated into the case, > > etc. In order to develop case designs that include a keyboard, we must > > Yes, shape effects ease of typing.

It might be worth designing a slightly different case in order to accommodate a usable antenna module. There is a danger of allowing one's self to be limited by the existing design. I would say change the case design if it will allow production of complete phones. > > for (;;) { ++pancakes; } > > You could do pancakes+=2; :) True.

Re: QtMoko v44 for Freerunner now available
Hi Thanks for the new version Radek, fresh installed on my GTA02! It's ok on the NAND, but on SD I'm unable to boot it. Qi apparently skips the card and it boots from NAND instead. Is it because of the issue with the v44 kernel for the GTA02? Thanks. Joif ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

What to see in software > distros? Anything else? What missing piece are you waiting for? Let me list the hopes I had when buying the Freerunner. They're mostly related to middleware, and start with the idea of a programmable phone, not a wireless computer. - tracking of billing in real-time, using a set of user-provided rules. In practice, telling me how many text messages I have left out of my monthly limit - programmable reactions to different calls - reject some callers, voicemail others, record unknown, set custom ringtones - compound communication model - most of the time I don't want to pay attention whether I'm sending a message via mail, XMPP or SMS, whether I call using GSM or VOIP, whether I connect the Internet via WiFi or GSM - what I care about are properties of the connection: reliability, security and cost. When I call someone, I usually want to just get connected, no to think about which program I need to run. Also, this approach lets store all communication history in one place. - a geolocation API (combining GPS, GSM and WiFi information) that will be able wake me up when I reach my train station. Potentially useful for determining reliability of communication (see above). These days what I care about is much more humble: reliable GPS (SHR + tangogps were the best combo I've seen so far), full communication logging (SHR was pretty good at this too), alarm (SHR alarm was wonderful) and PIM: calendar, some form of note making and todo list.

Well, the circuit itself was already part of the GTA04 schematics so it was not too difficult to extract that into an external PCB. And once designed it is easy to move the buttons a little around before it goes into mass production. So that it fits the case. > I think the really important issue in developing a hardware keyboard is > in the physical design; the arrangement of keys, how the shape of keys The arrangement of keys is more or less standardized, so there isn't much room for experimentation. > effects ease of typing, how the keyboard is integrated into the case, > etc. In order to develop case designs that include a keyboard, we must Yes, shape effects ease of typing. But also do the mechanical properties of the electric contacts. I.e. what their contact force is. You can only test that with having the electronics ready (at least in a prototype status). > first have designs for cases without a keyboard :-) Well, but what do you do if you design a keyboard where the mechanical switches are not available? Part of the experiment was to test how well these Panasonic things work, how easily they can be soldered, what they impose as the minimum distance between buttons. I.e. you can't do one without the other. And have to start somewhere... And, the shape of the keycaps can be changed and optimized. That is the good thing with 3D printing. > At present, we do not have this.

But without having this prototype, it wasn't clear if we could head for a case variant with keys at all. Usually in product design the electronics (and availability of components) imposes more constraints so that design follows function. I.e. a good industrial designer creates clothing for the internals. If you ask a designer to draw a sketch and then try to build electronics inside, you can no longer use standard components. Well, if you are Apple or Samsung, you can break this rule and set the standard for new components. But it is still useful to draw such sketches to know what we want... I.e. both parts are important and none can do without the other. > Also, I believe we should not limit ourselves to the existing case > shape.

However, I think it may be premature to start designing keyboard circuits. I think the really important issue in developing a hardware keyboard is in the physical design; the arrangement of keys, how the shape of keys effects ease of typing, how the keyboard is integrated into the case, etc. In order to develop case designs that include a keyboard, we must first have designs for cases without a keyboard :-) At present, we do not have this. As I understand it, Slyon's cases do not fit together properly and so we cannot build a complete GTA04 case from them yet (has this changed?) There are also no case component kits available. I think it would be more advantageous to spend time dealing with these basic problems. That way, we will have a solid base from which to build more advanced designs, including designs that incorporate a keyboard. Also, I believe we should not limit ourselves to the existing case shape.
