STM8 Programming

From SEGGER Wiki
Jump to: navigation, search


Universal Flash Loader Configurator, Universal Flash Loader, UniversalFlasher.exe or short UFL is the way to program many STM8 devices. Flasher STM8 is a legacy product. The Flasher PRO supports STM8 devices in conjunction with the STM8 adapter and many other devices.

Projects which were created for the Flasher STM8 are not supported by the Flasher Pro.
Please create a new project with the Universal Flash Loader in order to program your STM8 device.

Please note that without the STM8 adapter you have to connect the SWIM line to TCK and via a 1k resistor to PIN17.
