Hi Stanislav, If you want to use interrupts and u-boot, you will have to set things up on your own, it is outside the normal use of u-boot. Standalone is probably a good choice if you wish to pursue this. Be aware that you are using u-boot in a way that it was not designed to be used. You will have to add functionality (interrupt handling, possibly more) to your code and/or u-boot. The u-boot list will probably not be very helpful - when you do unusual things, other people will not have experience with the problems you have and thus will be unable to give much advice. From your other email: > Now we build our program directly into the source code of programs U-BOOT. > And we want to use interrupts. Note that, if you *link* your program u-boot (build directly into the u-boot source), you *must* use a GPL-compatible license for your program (i.e. your program must be Open Source - you must provide an offer of your modifications/source to your users). If you run your program "standalone", the u-boot licensing gives permission to use a proprietary license for your code which is running standalone. Best regards, gvb
