Re: Freerunner won't charge, and won't start anymore due to out of power
Alexander Frøyseth wrote: Does anyone know WHY it don't charge when it is off? My logic says that it is very important to have the option charge the battery when it is flat. I can't give you a simple answer. Charging is controlled by the PCF50633 chip, based on configuration values that are written to it by u-boot, Linux, and userspace programs. Some of these settings are preserved across a power-cycle (the PCF50633 has a small backup battery that's also used to keep the RTC running) so the behavior at startup depends on the software that you used during your last session. Another complication is that some Freerunners are capable of starting up without a battery while others are not (possibly due to different capacitor values on the internal power rails). I can give a few hints: - The current u-boot has a bug that means it will not properly charge from the wall charger. Try a USB cable into a PC instead. - Try to boot into the NAND u-boot menu (hold power and then aux) and then select power off. This may leave the device in a state were it will charge. Wait 15 minutes and then try to boot Linux. - Try booting through NOR u-boot instead (hold aux and then power) with either the wall charger or a 500mA USB connection, then try booting Linux. - If the device shuts off during one of the above attempts, let it sit for a few minutes and then try that same item once again I've written some u-boot patches that improve low-battery handling. Anyone who's interested can take a look at the openmoko-kernel list for more details, but be warned that the code is not yet ready for general distribution (i.e. anyone who tests it does so entirely at his/her own risk). ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

That's correct - u-boot is responsible for initializing the hardware (like a PC BIOS) as well as for loading and booting the kernel (like Grub). In which case why can't opkg update this? It should be possible to update it from Linux. The flash partitions are exposed as /dev/mtd* devices, and the kernel package updates its corresponding flash partition when installed. In the past there was a bug that interfered with writing to flash from Linux, and it was very risky to touch the u-boot partition because a mistake could leave you with a bricked device. Neither of these is a concern for the Freerunner, so it should be possible for someone to put an 'opkg' wrapper around u-boot. This wrapper would have to flash the correct u-boot for the revision level of the hardware (e.g. GTA02v4 vs. GTA02v5). Does flashing the root filesystem wipe out /home? yepp. that's a big disadvantage imho. Workaround: move /home to the SD card and then create a /home symlink on the root filesystem.

As I understand it the main problem is that a capacitor in series with the headphone output is too small, which means that low-frequency audio is cut off (the capacitor + the resistance of the headphones forms a high-pass filter). This is consistent with Kevin's observation that it sounded OK when connected to an Aux on another amplifier, because the resistance of that input is much higher than that of headphones. I don't know the actual cutoff frequency or how it compares to other products on the market.

If that is the case, then OM might be able to use a non-recessed 4-bin receptacle with a compatible pinout. That way, any iPhone adapters or headsets could be used with the OM phone.

Re: echo (was: ASU software - pre-pre-release impressions)
Crane, Matthew wrote: I've noticed that with GSM calls in general there is sometimes an echo. It can be very pronouced or barely noticable. It may be hw or sw, but it may not have anything to do with either caller's phone. If it doesn't happen consistently and is not reproducable, it's likely the network. IMHO. In some cases it might be from the network, if it was using a buggy or mis-calibrated echo-cancellation algorithm. However the Neo itself is also quite capable of generating an echo - some of the sound coming out of its speaker is picked up by its microphone, and is then encoded and sent back to the other caller. In my tests the echo went away when I muted the Neo's speaker or microphone, so it did not seem to be a network issue. The audio coupling between the Neo's speaker and microphone can be measured independently of the GSM stuff, e.g. with the 'Jaaa' audio analyzer from http://www.kokkinizita.net/linuxaudio/ or with 'xoscope'. Various ALSA mixer controls will affect the level of the coupled signal, but these also affect the intended sound paths (loudness of the speaker and sensitivity of the microphone). The mixer settings have to be selected to give the best compromise between these factors. I hope that the overall audio quality will be good enough once the mixer settings have been optimized, but I am not yet confident of this. Audio-quality reports from other Freerunner owners would be appreciated. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: proprietary firmware
Wolfgang Spraul wrote: Next we discovered that those reflashing tools had further issues: for example, they would only allow loading cryptographically signed firmware into the chipset flash memory. I don't see why the cryptographic-signing requirement is a problem. Sure it would be nice if every peripheral was fully open-source and hackable, but that's just not realistic. If you're loading a proprietary blob anyway, who cares whether or not it has cryptographic authentication? Furthermore, we see that for upcoming chipsets, vendors are switching from storing the firmware in flash memory to loading the firmware into RAM at run time. IMHO that's a good thing as long as they allow reasonable redistribution of those firmware blobs (i.e. so that OM can include them in rootfs images). In this case the firmware, whether original or updated, has to be loaded each time the device boots, requiring that the binary-only, restrictively licensed firmware updater be included in the OpenMoko distribution. If the device is designed to load its firmware on every boot, then there's no reason that it should require a binary-only tool. It should just be part of that driver's API. I have a MythTV box with a Hauppauge PVR-350 MPEG encoder/decoder card. It has proprietary firmware that's loaded on boot, but no proprietary tools are required. I just have to put the binary blobs into /lib/firmware/ and Linux does the rest. See the ivtv-firmware.c file in the kernel for details of how it's done. He suggested we treat any chipset with proprietary firmware as a black-box, a circuit. He suggested we ignore the firmware inside. If the firmware is buggy and the vendor needs the ability to update the firmware, we instead ask the vendor to reduce the firmware to the bare minimum, so that it can be very simple and bug free, and move the rest of the logic into the GPL'ed driver running on the main CPU. Did he have any real-world examples of vendors who have been willing to implement such a request? It seems like it would be a large change on the vendor's side and would require a lot of additional development and QA resources. It might even require the hardware itself to be designed specifically for that that usage model, e.g. the Hammerhead GPS used in GTA01. Also, as others have commented, the main CPU is a finite resource. It's not surprising that this is not a concern for the GNU project (their flagship text editor was known as Eight Megs And Constantly Swapping back in the days when that was a lot of memory) but it is a concern for users/developers like me. There are downsides: We will no longer offer reflashing tools to update proprietary firmware, under any license. For critical firmware bugs, we will accept returns, or in some cases fix the bug in-house. I purchased one of the original GTA01s with a -Moko1 GSM firmware. At some point I want to have this updated to a more recent and less buggy version, but I am not willing to mail the phone back to another country to get it re-flashed (unless OM will cover the shipping + customs costs both ways). I might be willing to take the phone in to a local authorized service center, but I would prefer to do the update myself (even if it required a proprietary tool). We will push vendors to simplify the functionality of their proprietary firmware, so we can implement more of this on the main CPU as Free Software. Maybe some vendors will even open up firmware for Free Software development, that would be the ideal outcome we are working towards. I think that's OK to push as a long-term vision, but in the short term I think that the best approach is cryptographically-signed blobs that the GPL driver loads into RAM through a set of API functions. That gives us the ease of updates (just copy new blobs into the firmware directory) and gives the vendors regulatory compliance (since only signed blobs will be accepted). It also encourages the model of having a GPL'd Linux driver talk to their device through a documented API, and may help to convince them to move more of the functionality onto the GPL side in the future. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Does anyone recall any software explanation for this? I've started to play around with the mixer settings, and it seems that they can be tuned to reduce both the GSM buzz and the echo heard on the remote end of the phone call. I don't yet have a set of working state files - the Neo's mixer is quite complicated, and I don't have access to the proper test equipment (tone generators, spectrum analyzers, etc). However, I've found that a good first start is to set to 0 the mixer controls of all of the unused components. There are some that are physically not connected (e.g. Amp Mono), and others that are unused in certain ALSA profiles (e.g. Mono Voice in the gsmhandset profile). I will eventually get around to creating a patch for this, but if someone else wants to do it first I won't complain. There is also a hardware side to this issue - if the hardware was really good at isolating the audio path from the radio signal, then there wouldn't be an interference problem in the first place. However I don't think it's reasonable to expect perfection. I can hear a GSM buzz similar to the Neo's when my friend calls me from a Motorola RAZR, and in general GSM seems to be much more interference-prone than my current CDMA phone. p.s.
