Alberto,
NXP has an awful "sunset policy" for tools and SDKs. More appropriately, they have no "sunset policy". I have spoken to the FAEs and regional people about this for years to no avail. While catering to an embedded market, there seems to be a lack of understanding that many embedded products have long life cycles; We are not all working on cell phones that get replaced every few years.
For example, for automotive or industrial controls that need a small change in 10-15 years, due to a recall or process change, the developer will need to setup a PC with the same tools. Old PCs crash, IT departments change domains, so the original PC may not be available. Then add the fact that NXP still requires licensing of old tools and refuse to find licenses for old SDKs and you have a mess.
Even compiler update servers for CW10.7 don't work anymore. Good luck setting up their Eclipse tools in 10 years.
TI on the other hand, has all of the old tools, operating systems, patches, and SDKs available. That is a REAL commitment to the embedded market.
It's too bad. But, I've figured by now that this will just be the way it is. You will find that sometimes other users on the forum can burn a copy of an old tool CD they have , or make an ISO, and send it too you. Make no mistake, there ARE copies of these discs somewhere inside NXP. It is impossible that there are zero legacy tool discs in the whole company world-wide. They just will not create and ISO and make it available
