Hello All, I have been using Mini2440 for custom application development for some time. I am planning to go ahead with commercial deployments of the application based on Mini2440. I would like to inquire, if currently Mini2440 is suitable for industrial grade applications. I am using Linux and the application communicates with other industrial devices using ethernet. There will no problem due to temperature or ambient conditions and protective casing will be there. My concern is about the hardware reliability of mini2440 for consistent performance. Thanks & Regards
Mini2440 Commercial use
I am in doubt, that the 2440 is the best choice for long time deployments. The processor is out of production for about 2 years and the availability of this boards will become worse in the future. I have a project started too on micro2440 because of the great documentations in net for the 2440, but plan to switch to the tiny6410 for future devices of my application. But maybe the people from FriendlyArm can tell more of the availability of the 2440's in the future...
Mini2440 is reliable especially when it's programmed properly. But Chip producers try to go further and further and increase MHz and Cores number. Atmel gives good example: it produce ARM and don't stop MCU production. Every niche must be filled - good business strategy. We have learned PDP-11, Intel 8088, Intel 80286, Intel 80386, 486, Pentiums, Motorola 68000, Intel X scale, Atmel, ARM7, ARM9, ARM11. And now more and more. What for me - I need a total control over device. I found mini2440 and I'm lucky with it! For my one core single brain (thank you, God!) it'll load me with a work for long years. Mini210 offers Android programming with no low level. To whom this is aimed? I think it's better to buy an Android tablet with the same SoC and with IOIO PCB attached. http://www.seeedstudio.com/depot/ioio-for-android-p-1023.html?cPath=132_206 FriendlyARM forum turns little by little into an Android forum. I can't say about this better then in the links below: http://www.joelonsoftware.com/articles/ThePerilsofJavaSchools.html http://www.eetimes.com/design/embedded/4238223/The-education-of-embedded...
I doubt the message "The processor is out of production for about 2 years". where you know this? we have been working around this for years, till now it is in good supply state. unless samsung over produce it? :) we provide odm design service, if you want quick product, you can contact us: http://www.quickembed.com
I read it on the Samsung page about half a year ago. But now, searching for the link, i saw that the production state is "mass production". Don't know if i messed it up or just saw it on a page that doesn't longer exists like a relating link in this thread: http://www.friendlyarm.net/forum/topic/1389 So sorry for confusing, it would be nice to stay developing for the 2440!
Samsung took the 2440 chip off the long term production calender about two years ago, but shows no sign of stopping production. Maybe you saw that. I wish they would do it in the new 32nm shrink and the chip price would drop. I know of at least 10,000 Mini2440 in the field in various commercial applications. Some outdoors in kiosks or security entry systems in all climates. The failure rate in the last 3 years is so low that there are not valid statistics. Definitely less than 1 per 1000 per year. This is for units that pass testing by the OEM. Sometimes there are missing connectors or other things that should have been caught by video inspection. A functional failure on test is extremely rare because the Mini2440 is shipped with a Linux based test loaded and working. As far as I know, the OEMs do not even use a conformal coating spray (but I would for dirty environments).
