A lot of other companies, even big ones like Sharp, tried Linux on handhelds and drew back. Ok, Sharp still produces Linux devices, but they are only sold in Japan. We are definitely in need of more experimentation with devices like this. The formula for standard phones isn't working. My phone has a calendar, web broswer and downloadable apps. I use none of those features because they are too expensive and hard to use for what you get on the little screen. My next phone is simply going to be the most reliable basic phone I can find and I don't care any more about these other worthless features. Most of my colleagues have the same opinion. So I'm probably going in the direction Nokia wants with the N800. All of my fancy apps will be on the N800 and the phone just becomes a Bluetooth modem. Now I can buy a cheap simple phone (free with my contract) and put my larger budget into the N800. Linux is key to allowing the needed experimentation on the N800 to figure out the set of apps that the public truly wants. Fully open source and open parts allow the community to continue supporting old devices when the manufacturer is no longer interested. While writing this it occurred to me that you could build the N800 in two pieces. I wonder if you could make a very small basic phone that could be firmly joined together with the display unit from the N800. They could share the CPU, battery, etc. Designing a phone like that is going to require some really innovative packaging. -- Jon Smirl [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

AFAIK you get this information (at least the interesting stuff: e.g. 3D-hardware) only if a)you sign a NDA and b)if your company will order a significant number of devices. So, I think, Nokia has that information but can not release it to the public. I hope someone there will decide that a hardware supported OpenGL driver would be a big benefit for the N800. Using a closed CPU like the TI OMAP in an open device like the N800 wasn't the best pairing. Maybe next time Nokia will use a similar but open processor like the Freescale MX31. They also could have picked open wifi like Ralink, Realtek or Zydas instead of the closed Conexant chip. Hopefully companies like Nokia will become more sensitive to open vs closed hardware as they build more Linux enabled devices. Another solution would be that the open source community can convince TI to release those technical documents to the public. This tactic has been successful in the past. A large customer convinced ATI to release the hardware documentation for the R200 series, but ATI closed their doc back up after the customer switched to another graphics chips. Nokia could simply inform TI/Conexant that the next generation devices will only use open hardware and see what their response is. -- Jon Smirl [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

I'd actually like to span across two 8GB cards giving a unified 16GB filesystem (or perhaps keep 1GB for swap and OS, and the remaining 15GB unified for media file storage). Even with 8GB cards I could find myself with insufficient room to squeeze in one more file on either card! :) Using dm/lvm to merge the devices into a single large device means that the cards are paired and can't be used individually anymore. If you take one out and put it in a reader, you won't be able to read it. The usb storage feature of the Nokia would also have to be modified to export the merged drive instead of the individual sd devices. It should be easy to point USB storage at a different device name. You could also improve the read/write speed of the system by combining the models into a raid0 array. That is probably easier than dm/lvm. But for raid0 to be efficient the devices need to be identical. The raid0 driver is a small module that can be built into the kernel, it will stripe the file system across both devices without any redundancy. -- Jon Smirl [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

I think I've broken my mmc with so much usb up and down :( It sometimes crashes. But then I format it again (the VFAT part) and it seems to work till crashes again. Don't reboot your Nokia device or unplug the USB cable without first unmounting the USB drive from the Linux system. This is almost certainly what is causing the errors in your MMC drive's FAT file system. The host system quickly buffers changes to the USB drive in RAM and then more slowly writes them out to the physical drive. Unmounting will force these changes to be written. If you unplug before they are written the file system will be partially updated which causes the errors you see. I've received very good help from Frantisek. And I think I'm going to get it. But I need another card in order to be sure about the results. I breath a little bit more again. This weekend I'll find out whether I can or cannot reboot the device from my mmc.

Would it be possible to write a generic remote control for the 770/N800, which talked (over TCP/IP or Bluetooth) to a master controller? The master controller would know that "turn TV on" really means "send IR code xyz" but the generic remote control doesn't have to. Are there any protocols to do this already? Also, UPnP seems to be possible with the 770/N800 Media Streamer as a controller, IIRC. There are several 11b/g to IR converter devices on the market but they cost $600. You might as well install something like a Media Center PC. But doing that makes the installation much more complicated than using a simple IR transmitter.

Not without providing at least 8ma VBUS power and a Mini-AB connector it isn't. Instead, it provides 0mA VBUS power and a Mini-B connector. :) The Tahvo chip has a USB transceiver that's not really OTG-capable.

I got the IR support working in half an hour and I still haven't gotten around to building a computer to relay IR signals over 11g. My media server is located in the basement. I use a UPNP AV player like the DSM-520 to play the media. There is no general purpose PC located near the TV. This set up works well to support playing media from TV's in four different rooms. The other trouble with using radio is the you have to tell the remote which room it is in. IR doesn't travel between rooms. If you carry an IR remote to another room, it won't still control the TV in the first room.

There is another problem: The N770 has a USB-Host mode (which is necessary if you want to run such IrDA adapters) but it does not power the USB port. I have made an adapter cable to power 5 Volts to an external HDD drive via USB and it worked very well. But I think for a IR transmitter this solution would be very unhandy. Is it no power at all, or just not very much power? With no power you can't even use a USB memory dongle. Hard disks take way more power than a USB port can provide. IR transmitter doesn't need much power, the one I am using now says it needs 100mA. And that's a peak value. It would be interesting if the N800 has a "powered" USB hostmode... -Klaus-- Klaus Rotter * klaus rotters de * www.rotters.de ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers -- Jon Smirl [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

You can get IrDA versions everywhere. http://www.buyextras.com/irdaadapters.html?gclid=CNDDxsHW1IkCFRFBgQodfF4i4Q But these are in the wrong frequency band for a remote control. The software is more interesting than the hardware. For example you could extract program guides from tv.yahoo.com. The Philips device has an activity based UI. You click on watch DVD and it turns on the TV, DVD and stereo and then sets everything to the right inputs. This would make a good add-on product if Nokia is interested. -- Jon Smirl [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
[maemo-developers] Using the N770/N800 as a remote control.
Did a SIR transmitter make in into the N800? I have a Phillips RC9800i remote control and I would like to replace it with my N770 or a N800. http://www.hometheatermag.com/accessories/0406philips/ I've been looking around for a IR transmitter/receiver in the form of a USB dongle and can't find one. You need a receiver in addition to the transmitter so that you can train the remote codes. It only costs a couple of dollars to build a remote compatible IR transmit/receiver USB dongle. Adding this capability would be very useful given the way I use my N770. -- Jon Smirl [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
