Side note:
I’m running through the fault1 app. I cannot use the the CWNANO, as I cannot get a good hardware test run on them. I have tried 3 different Nanos. That is in thread [Problem with CWNANO course SCA-101 - #2 by osok].
So I’m using my CWLite. I only call this out because maybe it has an impact on some of the default settings. I’m not aware that that is leading to the cause of my problems, it’s just a thought.
I have multiple LPC1114 boards.
I have one that is fully modified as show in the instructions, either on this workbook and in the Hardware Hacking Book.
I have a few others that are not modified
Using 1 that is not modified, I can run everything in step 3. I do get an error in the third block of step three.
scope.glitch.width = 40
scope.io.tio1 = "serial_rx"
scope.io.tio2 = "serial_tx"
scope.adc.basic_mode = "rising_edge"
scope.clock.clkgen_freq = 100000000 * freq_multiplier
scope.glitch.clk_src = "clkgen"
scope.glitch.trigger_src = "ext_single"
scope.glitch.output = "enable_only"
target.baud = 38400
#target.key_cmd = ""
#target.go_cmd = ""
#target.output_cmd = ""
I had to comment out the three commands at the end because I was getting an error if I didn’t.

The fourth block runs ok.
The fifth block, the one that tests communication using nxpprog.
- That worked with the non modified LPC1114 dev board,
- but didn’t work with the Modified board.
