the specification requires a reset duration of at least 10 ms. reset is indicated by the device to the host by removing the pull-up on D+ (host to device reset is a USB packet). we used 20 ms, but on some setups (USB host, stack, hub, and load dependent), this does not seem to be enough (no USB enumeration was performed afterward, at least for the DFU bootloader). increasing to 50 ms solved the issue on the affected setups. instead of USB suspend, the more proper USB disconnect is used. this mainly disables the pull-up provided by the USB peripheral. USB activate is not required since the follow up initialisation takes care of it. Change-Id: If5ceb3b8f7a8f134d4439fdd138dd12b46589f97
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
