OpenBench Logic Sniffer ported to Pipistrello LX45

POLS2s

mkarlsson ported the Open Bench Logic Sniffer code to run on Pipistrello LX45:

FYI, I have ported the Demon 3.07 code to Pipistrello LX45 FPGA board with the following changes:

1) The sample buffer size is increased by a factor of 8 from 24kB to 192kB
2) The interface is changed to serial (Pipistrello uses a FTDI 2232H High-speed USB chip)
3) The baud rate is increased from 115200 to 921600 to reduce the data upload time
4) The meta data has changed to indicated Pipistello implementation

I believe this is the largest buffer size of any of the “SUMP” implementations. It runs great with the latest JaWi OLS Java client.

    1. When I get my parallella board, I’ll probably port the core to it.
      The 2 boards I ordered in the kickstarter campaign are Z-7020 based and will have lots of room. With the embedded ARM cores, you can even build a portable LA with no PC at all.

      The boards you can order now are $99 , like the Kickstarter price, but will come with a Zynq 7010, not the 7020.
      The parallella has 1GB or 32-bit wide DDR3L currently running at 400MHz, which should be enough for 64 bits @200MHz with lots of room to spare (e.g. with spares enough for the CPU and refresh access).
