Hey NewAE community,
I am using the ChipWhisperer Lite and the STM32F303 target board. When triggering on channel 1 of the Logic Analyzer, I see that the ChipWhisperer Lite sends active-low pulse on channel 2. However, at the end it is always noisy. Do other people have this as well?
My settings can be found down below.
# Force a clock reset to clear FPGA DCM hangs
scope.clock.clkgen_freq = 7370000
scope.clock.reset_dcms()
# Configure Glitch Clocking
scope.glitch.clk_src = "clkgen"
scope.glitch.output = "glitch_only"
scope.glitch.trigger_src = "ext_single"
# Pull reset low (active)
scope.io.nrst = 'low'
time.sleep(0.05)
# Release reset (return to high impedance)
scope.io.nrst = 'high_z'
time.sleep(0.05)
# Set safe parameters (avoiding the 0 offset warning)
scope.glitch.width = 35
scope.glitch.offset = 10
scope.glitch.ext_offset = 0
# Routing. This is what connects the logic to the SMA pin
scope.io.glitch_lp = False
scope.io.glitch_hp = True
With kind rergards,
