BlueCore supports a mechanism called Device Firmware Upgrade (DFU) to enable its software and configuration data to be replaced. To guard against unauthorised changes, downloaded files can be verified by means of signatures.
The DFU Tools are a suite of programs that enable firmware and persistent ...
This a small hack I wrote to bypass the "No previous installation!" error of Microchip s C18 Upgrade.
Simply run C18Fake and select your C18 installation directory (create if necessary) and click Save button. A "fake" file will now be created into that directory, and this will fool the Upgrade into ...
