Richard:
I venture to guess that you have not looked at and tried out the modern 8051 derivatives that support on-board debug hardware via a JTAG interface. Despite your comment that you have shelves full of JTAG and ICE equipment there is a ring of naivety in your words. There was never any comment from you regarding my previous post at http://www.8052.com/forum/read.phtml?id=94217 but I think I still pretty much stand by my comments. From all I've read here it seems that the methods you desire to employ for supporting your products and debugging your code are tied firmly to a stick mired in the mud since 1985. I also ponder on what type of products you developed for clients 15 or more years ago that still require continuing maintenance today. I also have been making things for a long time (since the mid '70s) and it is exceedingly rare that I encounter the situation where old systems require code fixes or tweaks to keep them going (and I'm rather confident that some of the old stuff is still in use). In virtually all cases I encounter, where a prior client wants to actually upgrade an old sytem design, they are looking at changes that entail moving to newer hardware and software. When an old device has actually failed or outlived the original designed-to set of functionality it almost always seems that the fix or replacement desired by the client is something that needs to meet additional requirements. What clients were willing to get by with 15 years ago in terms of power sources, packaging, buttons, switches, connectoring, displays, performance, and connectivity is just not generally acceptable today. Where are you? You have also expressed quite a strong resistance to learning new skills keeping apace with modern technology. Such a stance will exert quite a drag on your ability to remain productive and competitive in the market of today. But then again if you are satisified that after you tear off the last page the calendar on the wall to just wrap things up and end it all ... then maybe your approach is OK. Michael Karas |
