ESP32 hardware setup

1

Hi team,

Just wanting a sanity check on my hardware setup for ESP32, I am using the sample simpleserial firmware(have also tried the .elf on the forked github) but I seem to get ack issues

Can someone confirm I have my hardware setup correctly so I can hopefully rule that out?

Hi,

There’s a Setup_CW308_ESP32.ipynb (if you’re using notebooks): https://github.com/newaetech/chipwhisperer-jupyter/blob/master/Setup_Scripts/Setup_CW308_ESP32.ipynb. Are you running that?

Hi Alex,

Yes I tried that setup and had made changes for Husky (scope.clock.clkgen_src and
scope.clock.adc_mul) however I would see nothing on my oscilloscope…

I am seeing signals with oscilloscope on a generic setup but I assume I have the trigger setup wrong still…

Trying to understand the issue but may just be out of my depths here, can’t seem to find much projects wise for Husky to compare to (assuming I have Husky specific settings wrong)

Do you mean you’re not seeing a clock being output from the Husky, or just no serial outputs?
