Bootloader Installation

The UHSDR bootloader is responsible for starting the firmware (the actual radio application) and more importantly, for providing user-friendly means to update firmware and/or bootloaders. It needs to be installed before a UHSDR TRX can run the firmware.

Since the documents may change over time and with different version of the bootloader AND are part of the UHSDR git repository, we do not replicate the content here, but link the documents current version in the UHSDR git repository.

The master document for first time bootloader install is available here and can be downloaded from pdf Download. The instructions in general also apply to mcHf 0.7 hardware. But since the mcHF 0.7 uses a different split of functional across boards, the pcb names and instructions cannot be directly used as is.

The master document for using the current bootloader to install/upgrade firmware or upgrade the bootloader itself is here
