I've just tried latest firmware and it was very pleasant to fly but I've noticed some yaw on ascending/descending and fast turning. Wanted to check logs but after clicking "Log Download" I can see this:
Init ArduCopter V2.7.1
Free RAM: 1485
FW Ver: 118
load_all took 5812us
?3 ?No dataflash inserted ?3
Except ugly mess around the message says that I don't have dataflash. Just checked, it's there and sits very tight! I wrote about this some time ago. To be honest, after like 10 flights I could not get any log. Ever.
Using console looks like it can see flash:
Testing dataflash logging
Manufacturer: 0x1f Device: 0x2701
NumPages: 8192 PageSize: 528
Format version: 28122011 Expected format version: 28122011
And using "dump" command I got something that looks like proper log but console hangs after dumping data.
I have APM2.
We've got a fix for that in 2.7.2. When that's released (in a few days), just erase your dataflash from the CLI and you should not have any problems going forward. BTW, that fix is already in the ArduPlane 2.60 code, which is out already, so if you want to do it now, you can load that code, erase your dataflash and reload the ArduCopter code.
Thanks for the info.
From what I managed to retrieve I can see that I have similar problem to guys in comments here http://www.diydrones.com/profiles/blog/show?id=705844%3ABlogPost%3A...
Lack of many variables like PID or errors. Do I have to enable them by my own somehow?
I was looking at http://code.google.com/p/arducopter/wiki/AC2_Logs but could not find any info about it.
