Open Workbench logic sniffer, flash unknown?

Hi,

I’ve received the Open Workbench Logic Sniffer this week and running into problems using it. There are some problems with the client code running on Linux but my major concern is the following output from the pump_loader executable:

root@laptop-danny:~/logicanalyzer/pump-loader# ./pump-loader -p:/dev/ttyACM0
PUMP loader
Opening serial port '/dev/ttyACM0' @ 921600 ... OK
Found PUMP HW: 1, FW: 0.1, Boot: 1
Error - unknown flash type (ff ff ff ff)
root@laptop-danny:~/logicanalyzer/pump-loader#

I don’t think the flash memory should return ff ff ff ff?

I would talk to ian at dangerous prototypes if you have not resolved this one yet. He is commited to this project and had done a lot of work to deal with many issues in the early builds.
