Thank you for the quick reply. What uboot version should I use? Are there recompiled binaries somewhere that would be suitable? Is it just a matter of uploading a new boot loader file using the uboot menu or is additional configuration of environment variables required? Sorry to pester with questions about that but wiki and forum are silent about the specifics around this.
