132 to 812500 bps in your Magnetite firmware build, follow these steps: 132 to 812500 bps in your Magnetite firmware build, simply add a
133 133 TR_BAUD_CONFIG=TR_BAUD_812500 argument to your ./configure.sh line,
134 * Run ./configure.sh like you normally would, selecting the UI-enabled config 134 and remember to pass the -B812500 option to rvinterf when talking to such
135 of interest for your target. 135 trace-speed-increased firmware.
136
137 * Go into the build directory, and before running 'make', edit
138 config/swconfig.cfg - it is one of the config headers generated by the
139 configure.sh process. In that configuration header file, change the
140 TR_BAUD_CONFIG setting from TR_BAUD_115200 to TR_BAUD_812500.
141
142 * Run 'make' or 'make ram' as desired after editing the swconfig.cfg header.

144 And of course remember to pass the -B812500 option to rvinterf when talking to
145 such trace-speed-increased firmware.
