this change is mainly relevant for the SIMtrace board, but also affects the others. First we ensure VCC_PHONE is not forwarded to VCC_SIM because the card could affect the signal (card could draw too much current or feed back current in). next we disable VCC_SIM. the card slot does not need to be powered, and the FPF2019 leaks current back to VCC_PHONE, even with forwarding disabled (the reverse current protection only kicks in when VCC_PHONE is briefly shorted to ground, but still leaks 0.6V). enable the ADC channels normally used to measure VCC, even if not used. the dedicated ADC pins leak current when left unconfigured. enabling them puts them in high impedance.

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
