We are about to release ICCAVR version 8.10.00, with support for CRC generation and production ELF file. The latter allows users to specify all the special control bytes (fuse, lockbits etc.) in the C source file and have a single output file for device programming. More convenient and less error prone than existing methods.
We are also working on some very exciting products. More details later when we can talk about them 🙂
