Try the char driver, it is simplest of three. > Assuming this to be the case, would it be best to use the char device > type and then use fseek to access a given address within the memory map > of the FPGA? IMO, using read/write functions to access FPGA registers is not a best way. Alternatives are: 1) use custom ioctl's. Very convenient way to communicate with driver from C userspace code. 2) use file under /proc or /sys to communicate with your driver. Convenient way to communicate with driver from shell scripts, and you don't even need device file under /dev directory in this case! -- With Best Regards, Vitaly Demyanec _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
