Open Bench Logic Sniffer / 0.9.5 client fails to open port on Solaris
Bug report:  The 0.9.5 client (which uses PureJavacomm as replacement for RXTX) doesn't work on Solaris.  0.9.4 (which uses RXTX) works fine.

Open Bench Logic Sniffer / 1.03 "16 channel, 8k samples, inside" firmware is broken
After loading up the 1.03 16ch/8k/inside firmware the OBLS stopped working, the symptom being that Sump said it couldn't find the device.  I assumed that meant the PIC firmware was somehow hosed, but looking at the design info shows that in normal mode the PIC just acts as a USB passthrough to the FPGA, so it's not the PIC firmware that's bad, it's the FPGA firmware.  I loaded up the 8ch/16k/inside firmware and that seems to work fine.

Open Bench Logic Sniffer / OpenSolaris success, and some questions
Just a FYI, I have OLS working on OpenSolaris.

Some questions:

I see mention of different combinations of samples and channels, e.g. http://dangerousprototypes.com/2010/02/ ... nalyzer-2/ says:

Currently the following memory/channel configurations are available:

    * 32 channels with 4k sample depth.
    * 16 channels with 8k sample depth.
    * 8 channels with 16k sample depth.

but http://dangerousprototypes.com/forum/in ... 61#msg4661 says that irrespective of the channels you only get 4K samples, which is correct?

I've found the newer firmware, but is there an "idiot's guide to upgrading"

Is there a FAQ somewhere with all this info in?

Thanks.
