I’m a little confused on this. The NXP site has apnotes that refer to this utility, and their site even has a download link for it, but the page or file is nonexistent. I read some things that suggest using Flashmagic instead. Is this the way to go for programming via serial port?
I’d stick to FlashMagic. They’re exceptionally quick updating it when new chips came out (they had the new 1300s and 1100s before they were available for purchase), and it works very well.
