Unfortunately we cannot provide many details on the GSM chipset due to very tight [http://en.wikipedia.org/wiki/Non-disclosure_agreement NDA]s.  However, this is not neccessarily required, since it interfaces using a standard UART serial line with the S3C2442.  On that interface, [http://www.3gpp.org/ftp/Specs/archive/07_series/07.05/ GSM 07.05], [http://www.3gpp.org/ftp/Specs/archive/07_series/07.10/ GSM 07.10] and other standardized protocols are used.

It should also be possible to use host mode with externally-provided power. This will allow the FreeRunner to be connected to a USB device and be powered and charging the battery if present at the same time.

** If your power source was not the Openmoko 1A charger, additionally connect a 47K ohm 5% resistor between the ID pin and ground to pretend to be the 1A charger.
+
−
 
+
−
In addition you need to make sure EN_USBHOST signal that enables the physical Host mode power generation and disables the USB -> PMU charging path is deasserted.  This may be taken care of automatically shortly by detection of the 48K resistor on a USB insertion leading to forcing EN_USBHOST deasserted.  The charge pump that generates the 5V in host mode doesn't seem to mind getting external 5V given to it, but the real issue is that the battery will not be charged at all if we leave EN_USBHOST asserted since one of its jobs is to stop that happening.

Distinguishing hardware revisions

Inside the Bootloader

Every hardware revision has its own u-boot image type. Thus, the bootloader has the revision hard-coded. The hardware revision is passed on to the kernel via the ATAG mechanism (ATAG_REVISION)

Inside the Kernel

The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.

From Userspace

The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.
