Open Bench Logic Sniffer / Re: Weirdness with channels 13-15
[quote author="manicolosi"]Thanks again EasyRider. I suspected it was busted. Just to clarify I have not enabled RLE and I've ruled out my cable too.

I'm going to try to get it replaced. Unfortunately, it seems there's no real support for this device either from SeeedStudio or from Dangerous Prototypes. I should have just paid a little more and bought from Sparkfun. They surely would have just replaced it for me.[/quote]

Sorry for the delay reply, Seeed will solve your problem with you.

Bus Pirate Support / Re: Buspirate 3.6 alive?
[quote author="james"]I seem to have same problems with BP behaving as if no firmware and not responding to terminal - v3.6 board date April 2012, in package dated 10/09/2013.

115200 8N1 via putty, also tried other terminal software. Am using latest drivers.

I have also tried OLS client and although the serial port is recognised, I get error "Capture aborted! Device not found!".

Order placed 23 December with Seeed and only just received.

If there are known issues with these boards, why are they still sending them out?

Hi James:
Sorry for the issue, we have check and rework all the stock at 12/31/2013. I will contact with you and send a replacement to you later.

Thanks
Kevin

Bus Pirate Support / Re: Bus Pirate v3.6 (apr 2012) Seeed 10/09/13 Almost DOA
We got some feedback that F232RL can’t work in Windows operating system recently and we did a serial test on different PCs and different operating systems.

As a result, we found some chips can’t work with the latest drivers on the following Windows operating systems:
•   Windows 8.1
•   Windows 8.1 x64
•   Windows 8
•   Windows 8 x64
•   Windows Server 2008 R2
•   Windows 7
•   Windows 7 x64
•   Windows Server 2008
•   Windows Server 2008 x64
•   Windows Vista
•   Windows Vista x64
•   Windows Server 2003
•   Windows Server 2003 x64
•   Windows XP
•   Windows XP x64

We are analyzing the issue and need some time to get the root cause. However, if you see the exact same behavior, you can follow the attached instruction to fix it quickly.

If you are not satisfied with this solution, kindly let me know and I will send you a replacement.
Apologize again for the inconvenience caused again.

Thanks

Bus Pirate Support / Re: Buspirate 3.6 alive?
[quote author="sqkybeaver"]since the buspirate is by far the most popular DP product, SEEED will usualy replace without requiring the defective units to be sent back.

there was a recent discovery, that the newest drivers from ftdi had problems with windows 8. look here for more regarding this issue http://http://dangerousprototypes.com/forum/viewtopic.php?f=4&t=6052&p=55828#p55827

I am willing to troubleshoot any defective unit, to help fix manufacturing or design issues, etc.. but please check for known issues first if your able to.[/quote]
