This is a step-by-step description of how the firmware is upgraded on a Neo with FLUID running on the device. Note that this process tolerates almost no variations. Stray from the instructions at your own peril. Instructions based on a posting by Werner (http://lists.openmoko.org/pipermail/openmoko-devel/2008-April/002605.html), thanks.
Please note: Update to MOKO9-beta firmware isn't recommended by OM, and probably won't fix any recent issues like #1024 at all. Use the latest firmware version instead.
Please see http://people.openmoko.org/joerg/calypso_moko_FW for more recent FW-images.
Please see http://people.openmoko.org/joerg/calypso_moko_FW/all_version__CHANGELOG.txt for changelog.
For now there is some moko11, which should fix #666 (compatibility with some 3G sim cards), and also has a new command AT+CSIM. It also includes fixes related to hardware flow control and wakeup interrupt.
This version is not supposed to fix #1024 (constant re-registrations leading to lost calls and messages). For a workaround use a distro where deep sleep mode can be deactivated.
We are planning to include this version in the factory image of the A7 run.
We recommend you don't update by following this procedure, unless you feel very comfortable with commandline. Don't miss-spell any FLUID command!
There is an SD-image, that greatly simplifies the whole GSM-update process - we suggest everybody who's not feeling completely comfortable with the procedure described herein use the image instead (not applicable to gta01 owners).
Warning: there are chances to _irrecoverably_ damage your GSM modem calibration data, thus rendering it useless on messing around with FLUID! Use only the commands from this wiki page! Never downgrade to a version earlier than Moko6, or you will render the GSM unusable (certain internal data structures changed between Moko5 and Moko6).
The GSM-firmware didn't differ from GTA01 to GTA02, as the GSM-hardware didn't either. This means you can flash MOKO11 (or any other recent GSM-FW) to GTA01 as well. According to mwester, this worked for him to update from MOKO1 on a GTA01Bv4 to MOKO10b2, by following the steps described herein (if the main firmware can't be started, see troubleshooting section for additional instructions).
Any reports on successful update, as well as problems encountered, or SIMs seen to work after update, all highly appreciated. Please add to the "discussion" tab of this wikipage. Thanks!
Phase 1: Preparations
- Download and install a distribution to your device that gives you SSH access. We recommend the fso-console image:
mickey@amethyst$ cd /tmp mickey@amethyst$ wget http://people.openmoko.org/mickey/images/openmoko-fso-console-image-glibc-ipk--20081028-om-gta02.rootfs.jffs2.summary mickey@amethyst$ dfu-util -a rootfs -R -D ./openmoko-fso-console-image-glibc-ipk--20081028-om-gta02.rootfs.jffs2.summary mickey@amethyst$ wget http://people.openmoko.org/mickey/images/uImage-2.6.24+r10+gitr75999+54524f4531c8b262431b794fea610d81bb351c86-r10-om-gta02.bin mickey@amethyst$ dfu-util -a kernel -R -D ./uImage-2.6.24+r10+gitr75999+54524f4531c8b262431b794fea610d81bb351c86-r10-om-gta02.bin
- Install http://people.openmoko.org/joerg/calypso_moko_FW/fluid_0.0+svn20070817-r2_armv4t_eabi.ipk on your device:
root@om-gta02:~# opkg install http://people.openmoko.org/joerg/calypso_moko_FW/fluid_0.0+svn20070817-r2_armv4t_eabi.ipk
- Install http://people.openmoko.org/joerg/calypso_moko_FW/s3c24xx-gpio_1.0+svnr4130-r2.1_armv4t.ipk on your device:
root@om-gta02:~# opkg install http://people.openmoko.org/joerg/calypso_moko_FW/s3c24xx-gpio_1.0+svnr4130-r2.1_armv4t.ipk
http://people.openmoko.org/joerg/calypso_moko_FW/moko11/calypso-moko11.m0 and place it into the /home/root directory:
root@om-gta02:~# cd $HOME root@om-gta02:~# wget http://people.openmoko.org/joerg/calypso_moko_FW/moko11/calypso-moko11.m0
Phase 2: The Lobotomy
- Make sure nothing is accessing the GSM modem. If you're using the fso-console image from the link above, this will happen automagically on boot. On other systems, kill processes as you see fit (for FSO it's zhone, frameworkd and gsm0710muxd; for SHR it's ophonekitd, frameworkd and gsm0710muxd). If you're using a stable (or andy-tracking) kernel from Feb 26 or later on GTA02, see below for simplified instructions on powering the modem on/off (if you use the simplified method to turn it off, you must also use the simplified method to turn it on; no s3c24xx-gpio invocations are needed).
- Power off the modem:
root@om-gta02:~# echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on root@om-gta02:~# echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on root@om-gta02:~# s3c24xx-gpio b7=0 root@om-gta02:~# stty 0:4:18b2:8a00:0:0:7f:15:4:0:0:0:0:0:0:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 -F /dev/ttySAC0 root@om-gta02:~# stty 0:4:18b2:8a00:0:0:7f:15:4:0:0:0:0:0:0:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 -F /dev/ttySAC0 root@om-gta02:~# echo -en "AT@POFF\r" >/dev/ttySAC0; sleep 1; echo -en "AT@POFF\r" >/dev/ttySAC0
- Launch the FLUID binary:
root@om-gta02:~# cd /usr/sbin root@om-gta02:/usr/sbin# FLUID_PORT=/dev/ttySAC0 fluid.exe \ -oo -od13,13 -b 115200 \ -f $HOME/calypso-moko11.m0
It should say something like this (takes a few seconds to load the file):
FLUID Revision 2.27, ... Bootloader: (reset target)
(this fluid command works even if the previous flashing was aborted and you have a broken and non-functional gsm-firmware due to this, as it uses the calypso ROM bootloader instead of the firmware bootloader. But in the case of non-functional gsm-firmware there's no way to power off the modem with AT@POFF command, therefore GTA02 users need to follow "modern kernel" (they might work even with older kernels) instructions and GTA01 users the troubleshooting section. Changing the -b to some lower baudrate might improve stability of flashing-process - the bootloader does autobaud, so you're free to use any rate)
- Start a second SSH session and start the modem:
root@om-gta02:~# s3c24xx-gpio b7=1
FLUID should now say something like this (it will take a couple of minutes to finish):
(fluid, version 3) ok Checksumming (269 * 8kB = 2152kB): ok Flash Detect: (0xEC, 0x22A0) Samsung K5A3240CT ok Program: (34 sectors, 267*8k=2136k) (*******************) ok
Note: If you get this instead: MESSAGE: File cmd.m0 not found, then you didn't do the cd /usr/sbin. Please pay attention ;-)
If FLUID does nothing, curse your bad luck and repeat the reset sequence, this is the whole 'echo 0/1, b7=0/1 stuff'.
- To verify that everything went well, do this in either of the two sessions (this doesn't always work but you can be sure that if fluid didn't report any errors, everything went well; you can check AT+CGMR output later with mickeyterm):
root@om-gta02:~# stty crtscts -F /dev/ttySAC0 root@om-gta02:~# cat /dev/ttySAC0 & root@om-gta02:~# echo -en 'AT\r' >/dev/ttySAC0; sleep 1; echo -en 'AT+CGMR\r' >/dev/ttySAC0 +CGMR: "GSM: gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-Moko11" root@om-gta02:~# kill %1
In some case you may receive this:
(fluid, version 3) ok Checksumming (269 * 8kB = 2152kB): ok Flash Detect: (0xEC, 0x22A0) Samsung K5A3240CT ok Program: (0 sectors, 0*8k=0k) () ok
It means the checksums of all sectors in calypso's FW and the new file to flash are identical. Probably you're trying to flash same version of FW that's already installed.
With modern kernels on GTA02 you can use this single command to "Power off the modem":
echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
Now you can start fluid as described above.
To "start the modem" you need to issue:
echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
Some users weren't able to complete the upgrade since they got an error while the firmware was uploading in the GSM chip (like Flash operation timeout).
However a solution has been found and it allows to use again the GSM modem. (please note this topic resides on devel-ML. Don't spread over multiple lists please, as it won't help in getting a response to your request just in time, and most people following the main thread likely will miss your postings anyway)
Use the following fluid command:
cd /usr/sbin FLUID_PORT=/dev/ttySAC0 fluid.exe -oo -od13,13 -b 115200 -f $HOME/calypso-moko11.m0
(Without FLOWCONTROL and with -oo to choose the ROM bootloader)
Then on a second ssh session please use this instead of the gpio command:
echo 0 > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on echo 1 > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
The firmware download should start now.
Half-flashed GTA01bv4 GSM Modem
For GTA01 the process of flashing when the main firmware is absent is more complicated as we have no easy way to power-cycle the modem.
I recently had to do a special process to recover my GTA01bv4 after breaking the gsm modem with a failed flash. The process is actually fairly simple.
- Unplug USB and remove the battery for about 10s to ensure that the GSM chipset is powered off, then replace the battery and re-connect the USB
- boot up from a distro that is neutered so that it does not access or turn on the gsm modem at all (this is a really important prerequisitive, as nothing should turn on the modem by touching MODEM_ON line until fluid is ready to connect to it); one can do that simply by disabling start of ophonekitd (and to be on the safe side framworkd too) on SHR
- issue this stty command twice:
stty 0:4:18b2:8a00:0:0:7f:15:4:0:0:0:0:0:0:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 -F /dev/ttySAC0
- cd /usr/sbin
- issue this fluid command (replace $HOME/filename.m0 with path to firmware you want to flash):
FLUID_PORT=/dev/ttySAC0 fluid.exe -oo -od13,13 -b115200 -f $HOME/filename.m0
- in another ssh session, issue this command:
echo 1 > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
After this, the flashing proceeded as expected. You don't need to do any special checks to ensure you have successfully flashed; if fluid reports everything is ok, it is actually ok.
There's a beta version for flashing MOKO11 to GTA02 Freerunner only.
It has proven to do a reliable job on flashing MOKO11 to GTA02.
- Download and untar http://people.openmoko.org/joerg/calypso_moko_FW/moko11/flash-moko11_uSD-image.tar.gz .
- read the README file that came with the tarball.
- (apply `sudo` or use root-terminal according to your taste ;)
- Insert a uSD to your PC, `umount` all uSD-partitions that might have been automounted (use `mount` or `df -h` to check). Do not use "safely remove" for this.
- `dd` the image "flash-moko11-2.image" to the physical(!) uSD-device (this will erase all data from your uSD!). `Sync` or `eject <device>`.
- Insert uSD to your FR, boot from NOR-U-Boot to uSD, wait until green "d_o_n_e" shows on screen (takes some 6min). Remove bat and uSD, or login via ssh. `mickeyterm` will access modem.
NOTE: If you don't have a uSD reader on your PC, you can `dd` from neo: install task-base-smbfs, u(n)mount /media/card, mount the directory in which you have the "flash-moko11-2.image" file and do the dd stuff. This will take about 12 minutes.
NOTE2: If you have Qi installed as your boot loader, power up to the NoR menu (Hold AUX Key, press Power button) and select Boot from SD (fat/ext2) to begin the installation process (per DocScrutinizer in #openmoko)
