Hi, Is there any Diy gang bang programmer capable of programming ARM cortax m3 and others micro-controllers. I have seen as many but you can program single IC at a time. programmer with multiple instance is good option.But It does not have stand alone software having access to more than one programmer. Please correct me if I am wrong.
Secondly these stop working {not responding right in the middle. You have restart the software as well as pulling USB Cable and reconnect it}. Have some ever tried to make it? Every practical suggestion will be appreciated.

... you mean "gang programmer".
That said, I have to point out your goal doesn't really make terribly much sense. DIY stuff is what you use when your time costs nothing, but professional equipment is unaffordable. Gang programmers, OTOH, are only ever needed in a professional environment, where even good equipment is still a lot cheaper than wasting time. I.e. you're combining requirements from two totally incompatible settings. What that means is it's not much of a surprise you're not finding anything.
In other words, if you think you can't afford a professional gang programmer, you don't really need one.
The goal with a gang programmer is speed. So their algorithms are optimized - DIY gear are often not running at optimum speed. And a professional gang programmer often have very good connectors for fast switching.
Older, more stupid, gang programmers did run the same sequence to all chips and only detected if one chip gave different answer - so they could program multiple EPROM chips and give green/red indication which chips got correctly programmed.
Today, they are normally multiple, totally independent, programmers that just have a single GUI for the operator. So you can switch devices while other devices are being programmed. But a streamlined process does take lots of time - a DIY solution will normally not support a streamlined process. So it may cost almost as much human time as a single-chip professsional programmer.
One thing here is the reliability. If you have a factory with a line producing gear so fast you need a gang programmer - if that programmer goes down, that production line will no longer get more units ready for final test. So a number of people will have nothing to do. And the gear they use for the test may only be available for a specific day before the factory retool for producing something else. So you don't want a DIY programmer to be a weak link in the production chain.
And you do not want that DIY programmer to have some unsuspected bugs. Maybe a transfer error or timing issue that sometimes results in a failed programming, or a failure to detect a problem.
In the end - todays intelligent chips do expect you to use an intelligent programmer for each individual chip. So the "gang programmer" is mostly just the unified software and potentially a hw interface box that expands one interface on the PC to multiple individual interfaces.
