hi, As a (very) easy starting point, I have uploaded another STM8 template project to http://www.cream-tea.de/public/STM8_SimpleTemplate.zip It is compatible with both SDCC and Cosmic compiler, and shows how to migrate between them.
The shell script makes the project and then uploads the hex file via STM8 bootloader, using a simple flash tool I wrote for Linux, MacOSX and Win. This tool is available at http://www.cream-tea.de/public/STM_BSL_flasher.zip. Note that this upload channel requires PC-COM to STM8-UART communication, which unfortunately is not available on the STM8 discovery board :-( However, if you have a suitable board (like me) or an USB-UART bridge (available from €15=$20), it should work nicely. Alternatively you can use a flash tool via debug interface (SWIM), e.g. Valentin’s stm8flash tool available at https://github.com/vdudouyt/stm8flash, which should work nicely with the ST-link on the STM8 discovery board.
