Can't use OpenADC with SASEBO-W


#1

Hi, Colin!
Recently I got the OpenADC Complete for SASEBO-W and wanna use it to capture the power traces. I followed the instructions at the newae.com/sidechannel/cwdocs/hwsasebow.html but still failed in the connection. I used both the aesexplorer software and chipwhisperer capture software to connect the OpenADC-FTDI scope.

Here is the debugging information:

Should I change my version of OpenADC python codes? Thanks for any info.

Hello,

The “ADVCLK” issues suggests the FPGA bitstream is some older version - where was the bitstream downloaded from? I’ve got to improve documentation on the latest release of that, as there was some older one floating around.

The most recent should be part of the releases (i.e. the zip from assembla.com/spaces/chipwhi … e_Releases), in chipwhisperer-0.08.zip\chipwhisperer-0.08\hardware\capture\sasebow-integrated\hdl - there is a bitstream there along with MCS file for the PROM.

Yes, the current bitstream version can run the SASEBO-W example successfully. Thanks a lot!
