The ST-LINK/V2 has limited internal buffering, such that trace data can be missed if the target is generating data at a rate quicker than the OpenOCD trace sampling. The issue of lost data is compounded since individual TPIU packets may be split across individual STLINK_TRACE_EP reads, and misleading results can occur if mid-packet loss occurs. This patch increases the frequency of checking for pending trace data with the aim of minimising such losses. Note: With the limited (I/O and memory) bandwidth of the ST-LINK/V2 there cannot, however, be a guarantee against trace data loss. The timer callback is only added when enabling tracing, and is removed when tracing is disabled. Change-Id: Ibde9794b77793d3068f88cb5c1a26f9ceadcbd8a Signed-off-by: James G.
