I have two comments that might fan the flames, but its just my opinion. I noticed VxWorks people are a lot like Windows programmers. Everything is packaged so nice and tight for them, that they hardly have to think. This is good, I guess, if you're concerned about time to market and have limitless computer resources (i.e. memory, disk space, processing power, etc). But when you are talking about embedded systems, these are the very things that are limited. VxWorks has gotten to the point where it is the Windows of the embedded world. It is hardly surprising that a VxWorks programmer has hard time with anything different. My second comment concerns Linux and embedded systems. At my new job, I am now working with Linux on a single board computer (SBC). These SBC's have PII processors (1.2Ghz), 1Gig RAM, Gigabit Ethernet, etc. I hardly consider this an 'embedded' system. Though we use this SBC for a very specific purpose, I have a hard time convincing myself that I am working on an embedded environment. Of course, I have also worked on the Microchip PIC17X processors. This is an 8bit processor (10Mhz), with 906 bytes of RAM for data, 32K bytes of RAM for code. The only communications with it is via a serial port or a JTAG emulator. Comparing these two environments, its pretty clear which one is 'embedded'. Every time I hear someone talk about 'embedded Linux', I just have to give off a little chuckle. ;-) --jc -- Jimen Ching (WH6BRR) [EMAIL PROTECTED] [EMAIL PROTECTED]
