@subsection eSi-Trace Configuration
eSi-RISC targets may be configured with support for instruction tracing. Trace
data may be written to an in-memory buffer or FIFO. If a FIFO is configured, DMA
is typically employed to move trace data off-device using a high-speed
peripheral (eg. SPI). Collected trace data is encoded in one of three different
formats. At a minimum, @command{esirisc trace buffer} or @command{esirisc trace
fifo} must be issued along with @command{esirisc trace format} before trace data
can be collected.
OpenOCD provides rudimentary analysis of collected trace data. If more detail is
needed, collected trace data can be dumped to a file and processed by external
tooling.
@quotation Issues
OpenOCD is unable to process trace data sent to a FIFO. A potential workaround
for this issue is to configure DMA to copy trace data to an in-memory buffer,
which can then be passed to the @command{esirisc trace analyze} and
@command{esirisc trace dump} commands.
It is possible to corrupt trace data when using a FIFO if the peripheral
responsible for draining data from the FIFO is not fast enough. This can be
managed by enabling flow control, however this can impact timing-sensitive
software operation on the CPU.
@end quotation
@deffn Command {esirisc trace buffer} address size [@option{wrap}]

option is specified, trace collection will continue once the end of the buffer
is reached. By default, wrap is disabled.

to analyze collected trace data, these values must match.
Supported trace formats:
@itemize
@item @option{full} capture full trace data, allowing execution history and

addresses.
