Begin to document how to get the firmware, how to build it, how to flash it, how to hack on it. Some parts are not there yet.

<para>The Firmware is the Software that is running on the
|
|
Microcontroller of the SIMtrace hardware. The Firmware itself
|
|
consists out of a couple of components for different parts of
|
|
the system. Besides the source code for the firmware you will
|
|
also need to have an ARM Cross-Compile Toolchain, a copy of the
|
|
SAM7 utilities to initially program the device or recover from
|
|
a fatal error and dfu-util to update the main part of the firmware
|
|
using the Device Firmware Update (DFU) mode.</para>

<para>The SIMtrace firmware is based on the OpenPCD RFID Reader Firmware and the
|
|
SIMtrace firmware code is located in the OpenPCD repository. You can use the
|
|
<command>git</command> to clone the repository.

<para>The firmware consists out of two separate binaries that will be concatted
|
|
and flashed into the NOR flash of the microcontroller. The main part is the dfu
|
|
program that will handle basic USB functionality and respond to Device Firmware
|
|
Update (DFU) requests to allow to update the firmware in the NOR or execute
|
|
software in RAM.
