How will the firmware be updated? I've basically got an unusable RPi, since the February 7th update. I'm running bfgminer 3.10.0 on Ubuntu with no issues. I started to install cgminer, but it would have taken me an entire day... Bfgminer is much easier to install.
While my BabyJet has been running, I've tried to get the RPi to work, several times, from scratch. Both Raspian and MinePeon will load, but neither will run. Frankly, I'm not impressed with these RPis.
My BabyJet ran with the RPi for 10 days, until the February 7th update was pushed out. HashFast even sent me a new SD card for the RPi, but nothing changed. The only issue since running on Ubuntu has been pool-related.
I bought my BabyJet to make money, not beta-test for HashFast (at my expense)

Now, to figure out how to overclock with bfgminer...

Again; anyone experiencing large amounts of errors will likely be fixed by the pending firmware release. It's normal to have say 2% or less errors, but if you see huge strings of them, this is a firmware issue. It will be fixed. Please be patient. Making support tickets with these complaints will get the same response I'm here giving you now, as I'm telling them to.
I know it's hard to have patience at this point after all this, but please try. I've only been @ Hashfast since December, and I was one of many Engineers hired to fix things and get reliable products out to everyone waiting. I wasn't around when any business decisions were made that affected shipping dates, so I can't comment.
Keep in mind, if you do get an RMA, it's shipping with the same buggy firmware you probably have now, so you could end up with the same problems, and you'll be out the time, effort, and downtime while we ship you another. Also, it pushes further out any upgrade kits or MPP boards, as we must divert boards for this purpose, and then it's going to take many Engineer-hours going back over every board sent back to see why it was sent back. (Hours that could be better spent)
