Osmocom SIMtrace 2¶

Osmocom SIMtrace 2 is a software and hardware system for passively tracing SIM-ME communication between the SIM card and the mobile phone, and remote SIM operation.

It is a followup of the SIMtrace project, providing more functionalities (e.g. remote SIM operation) and supporting multiple boards (e.g. SIMtrace with SAM3S, sysmoQMOD).

Hardware¶

The SIMtrace 2 firmware supports several boards.
The firmware is written for a ATSAM3S4B micro-controller, replacing the old AT91SAM7S64 used by SIMtrace and not recommended for new designs.

Note: The SAM3S is now also marked as not recommended for new designs.
It can further be replaced by the pin-compatible SAM4S, in the future.

SIMtrace¶

The SAM3S is pin compatible with the SAM7S.
This allows to continue using the same SIMtrace board, just by replacing the micro-controller.

Note: This hardware is open source.

sysmoQMOD¶

The SAM3S micro-controller with SIMtrace 2 firmware is also used on the sysmoQMOD board to provide remote SIM operation capabilities.

Note: This hardware is not open source.

Firmware¶

The SIMtrace 2 firmware source code is available here but is still under development.
Once ready binary files will also be released.

The SIMtrace 2 firmware can only be flashed on hardware with ATSAM3S4B ARM Cortex-M3-based micro-controllers.
It is not compatible with the older SIMtrace hardware using AT91SAM7S64 ARM7TDMI-based micro-controllers.
