Calltrace does not continue after first time hitting break #4
Description
TL;DR
px4_breaktrace does not continue to run after break despite continue
The MCU halts forever and thus only one function call is sampled.
What?
I want to create a callgraph for some SPI function. To do so, I run:
python3 -m emdbg.analyze.calltrace -v --px4-dir ~/PX4-Autopilot --target px4_fmu-v5_default --jlink --sample 60 -ex "px4_calltrace_spi_exchange"
with px4_calltrace_spi_exchange defined like this in fmu.gdb:
define px4_calltrace_spi_exchange
px4_breaktrace spi_exchange
end
Expected behavior
The MCU should continue to run after hitting the break point.
Note: The function px4_commands_backtrace does call continue after break and some printf
