sim_pbkdf2

Hello i have setup the pbkdf2 on latest vivado and ran the simulation that you have, but for the dat output is undefined. i have attached a picture with my problem, can you advise on how to get an output?

Initial setup procedure

Hi JarrettR, I'm Xiaotao from Tsinghua University, China. I'm working on a project where I plan to collaborate cocotb with GHDL. I saw your post on cocotb/cocotb#304. It seems that you have found the way to make it work. Would you please give me some information about that? Thank you so much!

Hello,
I am trying to simulate the PRFfunction you have written.
It runs for around 6.5 ns when ptk_valid_o = '1' , but the ptk_data_o and ptk values remain undefined.
Any advice on the possible problem?

FGPA

Hi.What is the speed at which the price of the device, FGPA ?

additional setup issues

FPGA/host/run.sh shows:

java -cp wpa2.jar Wpa2

... but this currently fails with:

Error: Could not find or load main class Wpa2

This looks closer:

sudo java -cp wpa2.jar WPA2

... but this also fails (at least on my setup), with:

Firmware upload time: 101 ms
4 FPGA's found
FPGA 0: FPGA configuration time: 79 ms
Warning (try 1): error sending control message: Connection timed out
Error: bus=001 device=027: selectFPGA: error sending control message: Connection timed out

dmesg shows:
