New Revision of the BeagleLogic cape WIP

A project log for BeagleLogic

Turns your BeagleBone Black/Green into a 14-channel 100Msps Logic Analyzer

What's new:

Removed the cape EEPROM as it wasn't being utilized. All the configuration is handled in the BeagleLogic system Image.

Added a DS1307 RTC to keep time so that logic captures can be correctly timestamped. This will be reflected in the software as well.

Add a LDO with 3.3V / 1.8V select on Input side for configurable logic level thresholds. BeagleLogic should also be able to tolerate +/-12V logic signals, will be working out the best way to make it happen.

Stay tuned for more rev2 updates!

Can I be added to the list for a bare board? I love this project and I'd really like to try it out!

Will do. I'll contact you with further instructions once I receive the boards for this revision.

Also, could you please explain or refere to documentation explaining how to you disable eMMC so that the last 2 channels (13 & 14)  can be used.

Thanks Kumar, but cant get channel 13 or 14 to work with BeagleBoneGreen. There is a possibility that my BBG was damaged because of applying input signals to these pins before disabling the eMMC.

I've updated this log, there's one more step to go so have a look again, hope it should resolve the issue if there's no hardware damage.

Kumar, do you have a projected completion date for the new revision? software update? wonderful project - appreciate all your hard work!

Kumar, any movement on version 2?

  Are you sure? yes | no

HV clamping is yet to be incorporated as of now. I expect the prototype boards to be sent to fab by the end of October. It should be possible for me to ship a bare board to you, let me know if you want one.
