We need at least one per IN/IRQ endpoint, as well as at least 3 for every OUT endpoint. Plus some more depending on the application, in case of cardem there could be one in uart_tx and one in uart_rx. So for cardem, it should be 7 per slot, resulting 14 for dual-slot devices like OWHW and QMOD. Given that we have plenty of RAM available (utilization up from 49% to 56% with this change), we can be on the comfortable size and easily have 20 buffers for now. Future MITM / triple-play applications likely need more. Change-Id: I022ba3bb3e1f5fd0c364aafe1a23f8fd9b2d8499 Related: OS#4251
SIMtrace v2.0
This is the repository for the next-generation SIMtrace devices, providing abilities to trace the communication between (U)SIM card and phone, remote (U)SIM card forward, (U)SIM man-in-the-middle, and more.
This is under heavy development, and right now it is not surprising if things still break on a daily basis.
NOTE: Nothing in this repository applies to the SIMtrace v1.x hardware or its associated firmware. SIMtrace v1.x is based on a different CPU / microcontroller architecture and uses a completely different software stack and host software.
Supported Hardware
At this point, the primary development target is still the OWHW + sysmoQMOD device, but we expect to add support for a SAM3 based SIMtrace hardware board soon.
The goal is to support the following devices:
- Osmocom SIMtrace 1.x with SAM3 controller ** this is open hardware and schematics / PCB design is published
- sysmocom sysmoQMOD (with 4 Modems, 4 SIM slots and 2 SAM3) ** this is a proprietary device, publicly available from sysmocom
- sysmocom OWHW (with 2 Modems and 1 SAM3 onboard) ** this is not publicly available hardware, but still supported
This Repository
This repository contains several directory
- firmware - the firmware to run on the actual devices
- hardware - some information related to the hardware
- host - Programs to use on the USB host to interface with the hardware
