I have discussed with the website developer, and hope them can fix the url problem as soon as possible. Becaus they have update the forum version, the previous url type can noe be used, and so I have asked them to give out a good solution to the problem you all mentioned. Please give them some time. Thanks for your suggestion and support. Hope we can have a nice meeting in future when I go abroad.

About the Actions, they now have contribute many resource to the open source field, and we LeMaker are also now editing the documents from them and will publish all the configuration files in the LeMakr community. So in my opinion, I trusted Actions, and their atttitue to open source also give me confidence.
And from the i.MX6 datasheet, the temperature range has 3 level: comsumer, extend consumer, auto. The basic is -40-85, and middle is -40-105.

And I also talked with many other people about the sata, GMAC and USB3.0. Becasue the Acrions S500 has USB3.0 on it, and now the speed of USB3.0 to GMAC is about 700Mbit/s. And I also think with the USB3.0, it is more flexible to extend more high speed interface. But maybe it sure will need more cost on the adapter board such as USB3.0 to GMAC or USB3.0 to SATA. |

Understandable. But for exactly these reasons web servers include URL rewrite engines. You modify the request dynamically with regular expressions before it even reaches the application layer (forum software). |

But there is a bit more on a board eg. DRAM?
Thx anyway for the useful insights into Actions' position now regarding open source (hopefully in the original meaning of the term). Time will tell...

Well, there are more problems associated with.
1) Everyone is only talking about sequential tranfer speeds. But disk accesses suffer from other problems as well, namely latency and random accesses (therefore exist technologies like Native Command Queuing to better deal with multiple requests simultaneously). USB2.0 and most USB3.0 implementation simply suck in this area caused by lack of 2)
2) USB3.x has an optional feature called USB Attached SCSI. When this is implemented on both sides of the USB connection not only sequential transfer speeds increase heavily but also random I/O gets really faster. Unfortunately most people don't even know what this is (and therefore don't demand this feature from vendors)
3) USB has an optional feature called SCSI / ATA Translation. With this feature it's possible to query S.M.A.R.T. values from disks or trigger S.M.A.R.T. selftests. Very important if you want to keep an eye on drive health (some USB implementors have own standards for transporting S.M.A.R.T. over USB but relying on SAT is always the better choice).
So while disks connected to a consumer grade USB3.0 controller might look as fast as when connected via SATA (since people tend to only care about sequential speeds and 'measure' always with crappy tools like dd -- useless without appropriate parameters -- or hdparm -- useless in '-tT' mode since tampering disk speeds with RAM speeds) without the stuff mentioned above they will usually fail when it comes to random I/O and monitoring drive health.

I have told Freescale to do the temperature test, and we will release the report when the board can be availble for marketing. And LeMaker also will do the test.
I have also just finished a meetting with the Freescale guys 30 minutes ago.

Thanks for the good information. I have send this to the Actions engineers.

The forum url link problem seems has been fixed. You can test it.
But the wiki pages url can not be fixed, because I have move the old page to the new page without leave the re-direct in order to get more clear structure. That's is my fault. I have added a prefix to all the old Banana wiki pages.
