ChipShouter CW520 Open Coil Fault

Embedded Security ChipWhisperer Hardware

I have a ChipShouter I recently purchased that does not seem to sense the coils as the “open” and “Fault” LED’s come on at powerup. I know the coils are fine, I tested them on another ChipShouters and they work. Any recommendations on how to proceed?

Hi,

There is a known issue where the output protection resistors can fail, causing the ChipSHOUTER to report a probe open error, even when a probe is present (detailed at https://github.com/newaetech/ChipSHOUTER/blob/master/documentation/ERRATA_NAEER01.md). Has this issue been present since you got the device, or did it appear after some use?

Either way, can you shoot an email over to support@newae.com so that we can get a support ticket setup?

Thanks,

Alex

Alex,

It worked for a short while but not long. Maybe a few hours? I will setup a support ticket as you’ve suggested.

Thanks,
David
