This is commandline utility for Diolan bootloader. OLS - Logic analyzer (http://dangerousprototypes.com/docs/Open_Bench_Logic_Sniffer) OLS uses modified bootloader. The original fw_update tool does make life harder. I have therefore created this tool. Simple, yet effective. License is yet to be added. For now assume GPLv3 license. There is some usage information / documentation in the dangerousprototypes wiki: http://dangerousprototypes.com/docs/Logic_Sniffer:_Comprehensive_update_application To compile you need the libusb-1.0-0-dev package. (This is not the same as libusb-dev !) Furure plan includes integration with ols-loader.
