How does Keil compare to GCC for ARM7 development? I'm in the process of choosing hw consultants for a medium size project and some use keil and some use gcc. I'd like to know the gotchas involved in going with either option...

There is very little difference between the two from a coding/development standpoint. The only thing I think you should consider is not specific to these compiler. Maintenance:

  • Will you be able to maintain the software if you do not have access to the Keil compiler or will it be a minor cost?
  • Also what debughardware/JTAG is supported and what will the cost be if you need to get some?
  • What will the cost be if you have to move from one compiler to other compiler due to having to switch developers later?

Unless you are very cost sensitive I think the real question is who will do the best job since the compiler will be a minor problem.
