Title: SUMP Logic analyzer mode not working in v6.0
Post by: garyservin on January 09, 2012, 04:37:24 am
Hi Ian, I'm using the bus pirate as a logic analyzer with jawi's client. With firmware 5.10 everything work perfect, but with firmware 6.0 I can't capture data with sampling rates higher than 1 KHz. I've tried the client's versions 0.95 beta 2 and 0.95 final with both firmwares (5.10 and 6.0) in Linux and Windows with 32 and 64 bits java 1.6 u30 and 1.7 u2, with the same results (not working at higher than 1 KHz sample rate). Sorry if this is the wrong place to post this problem.

Thanks!

I am aware of this bug and am working on it.

Hardware v3 goes nuts, and hardware v4 it totally unusable beyond the first capture (USB falls apart). 1KHZ seems to be the limit to get any capture, then it crashes both versions.

I looked through the change history, and there is nothing different about SUMP from v5.10 to v6.0. I will run under debug, but this could be a big issue that is not resolved soon, especially on hardware v4.

Please try this firmware, it seems to work for me. The mode tracking variable was changed from static to not, sometime between moving to the new SVN, that is why it didn't show up in the revision history.

Thanks a lot Ian. I'll try it and let you know the results.

Please note the file says v4, but it really is for v3 hardware :)

Thanks for the update! It seems to work now in Windows, but I'm still having problems in Linux (now I can't even capture at 1 Khz, firmware 5.10 can at all sample rates), but I think it has something to do with my OS.

If anyone with a bus pirate 3b could try it with Linux would be great.

Thanks again Ian!
