USB: increase USB reset time USB reset can be signaled by pulling low USB D+ for at least 10 ms, according to the USB specification. This force a re-enumeration. This time is increased to 20 ms to work with more USB HUBs. Some SAM3S based board have external D+ pull-up mechanism (such as SIMtrace) which needs to be used to pull D+ low. This is a legacy mechanism from SAM7S history. This mechanism is not required anymore on the SAM3S, and the qmod does not use it. When the USB HAL is suspended, the transceiver is disabled, causing D+ and D- to be pulled low. Then the HAL is activated again. This is particularly required when DFU is started (and enumerated), and after flashing the SAM3S switched to the main application (without reset), so it can properly re-enumerate. This board difference is now defined on the board header. Change-Id: I9b58d8101c2fcf5595026b675728826af26127a3
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.
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:
