Hello again everyone, I just put out new firmware builds for both FCDEV3B and Openmoko modems:
ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/fcdev3b/fcdev3b-nosleep-fw-20190112.tar.bz2 ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/fcdev3b/fcdev3b-prod-fw-20190112.tar.bz2 ftp://ftp.freecalypso.org/pub/GSM/GTA02/gsm-fw/moko-new-fw-20190113.tar.bz2 The first version (fcdev3b-nosleep-fw-20190112) is for the few FCDEV3B V1 boards out there (the ones which can't sleep), the next fcdev3b-prod-fw-20190112 version will be the one flashed into our new sleep-capable FCDEV3B V2 boards when I ship them, and the last moko-new-fw-20190113 version is for Openmoko GTA01/02 modems. The sleep mode improvements for legacy Openmoko modems with this new fw are the same as on our new FCDEV3B V2 boards: * During those time windows in which the modem is disallowed from going into deep sleep by the UART activity timer (10 s after each transmission from the AP host to the modem on the AT command UART), previous fw versions needlessly suppressed big sleep in addition to deep sleep, allowing only small sleep. The present version goes into big sleep during these time windows, saving more power. * Some Openmoko devices suffer from a hardware defect that requires disabling deep sleep. Previous fw versions did not provide a sleep mode configuration that allows big and small sleep, but not deep sleep, forcing the user to choose between small sleep only or big sleep only on no-deep-sleep hardware. OM AP software distros have been using the big sleep only AT%SLEEP=2 config in these circumstances. Our new fw offers a new AT%SLEEP=5 option that allows big and small sleep, but not deep sleep, which should be ideal for deep-sleep-deprived OM hardware. The default is still AT%SLEEP=4 allowing all 3 sleep modes (small, big and deep sleep), just like before. Please remember, though, that the firmware binaries are different and NOT interchangeable between FCDEV3B and GTA01/02 targets. The hardware is very similar, but not identical, and the small diffs in the hw do require separate fw build configurations. What would happen if someone flashes the wrong fw image by mistake? Answer: * If a GTA01/02 fw image (either legacy mokoN or one of my recent FreeCalypso builds) is flashed into an FCDEV3B, it shouldn't fry anything, but it won't work: it won't detect our Spansion flash chip, and it won't find our FFS. * If a firmware image built for the FCDEV3B is flashed into an Openmoko modem, it won't physically fry anything either (there will be a bunch of floating inputs, but then OM's own legacy mokoN firmwares did the same), but it may corrupt your FFS badly enough to where you would need to restore your FFS sectors from a backup with fc-loadtool. Our recent fw versions have re-enabled flash chip autodetection and thus OM's K5A32xxCTM flash will be recognized, but the corresponding FFS config entry is meant for future FreeCalypso modem products, not for OM, and the two FFS configs are different: OM used an inefficient FFS config for their flash chip, we have to keep their config when running on their hw for compatibility, but I have replaced it with a more sensible config for our potential future hw that may use the same chip. And of course there are application functionality diffs between the two fw builds: * Calypso GPIO 1 is an output on both platforms, but serves very different purposes: in OM's version it is an interrupt to the AP, whereas on our FCDEV3B it controls the loudspeaker amplifier just like on TI's original D-Sample and Leonardo boards. Thus fw builds for the fcdev3b target include our custom AT@SPKR command for controlling this speaker, whereas gtamodem builds include the AP interrupt generation code instead. * MCSI is brought out on our FCDEV3B, but not on OM's hardware. Our fw builds for the fcdev3b target include our custom AT@VPATH command for playing with MCSI, whereas our gtamodem fw build configures those 4 pins (unconnected on OM's hw) as dummy outputs to keep them from floating. So enjoy the new sleep-enhanced firmware, but be sure to flash the correct version for your hw!
