"Check out my newly assembled Hexacopter"

"Ok. I put 2.6 back on and still haven't been able to reproduce my original problem. Maybe a new, uninitialized chip needs to have a block erase done at least once?"

"Bob, I just pushed a change to master that forces the block erase command to be executed. "

"Ok, thanks for checking. Let me know what else you find out"

"Yes, I just commented out line 204 of DataFlash.cpp: if (format == DF_LOGGING_FORMAT_INVALID) {) After I ran that erase, my logs started working normally again.   After some more testing, it seems that ChipErase is working OK for me now.…"

"Just so I understand Using the patch at http://code.google.com/p/ardupilot-mega/source/detail?r=8845bfb16ea69bac0c3351ccc971a884fbe38905 Are you saying the check that the check erase failed? i.e. it gave a false positive that the chip erase…"

"Craig, I tested this on my board and it did not detect the problem (I stuck a Serial.printf inside the check to make sure).  Going back to the old way of erasing (page at a time) did fix my issue though.  It seems like my board fails in a…"

"Hi Yovi I noticed the erattum last week and we implemented the correction on Tuesday.  I had to get a couple of the dev team members to test the fix yesterday as I actually have yet to find a dataflash that fails the chip erase but I…"

"Please share here if you got the answer from Tech support team.   Thanks"

"The dev team is aware of this issue, which affects a small percentage of boards. The next version of the code"

"Thanks for putting that info there Yovi - I hope the dev team sees this.  Is there any way to bring it to their attention? I reverted my APM2 boards back to v2.34 today and so far everything seems to be working fine.  My suggestion to…"

"I'm getting a similar problem.  My APM2 is brand new.  The first few flights the logs were fine. I downloaded them once and then cleared them through the planner.  Since then, I have never been able to consistently create new…"

"I'm running Arduplane 2.40 and I'm getting the same thing on multiple boards. I think that the recent firmware might have a bug?  But I'll try some of the suggestions listed here."
