Thanks, I'll try this.
Happy Holidays to you and everyone else too :)

Hi,
I’ve created a branch with a compilable STM32F103RC example:
https://github.com/salkinium/xpcc/blob/feature/stm32f103_support_experimental/examples/stm32f103rc/blink/main.cpp
The fastest clock configuration from internal clock is only 64MHz (8MHz / 2 * 16) and NOT 72MHz, which is the max. allowed Frequency. Consult the STM32F1 Reference Manual (RM0008) Chapter 7.2 (Clocks) for details:
using systemClock = SystemClock< Pll< InternalClock, MHz64 >, AhbPrescaler::Div1, Apb1Prescaler::Div2 >;
The clock tree is almost identical to the one from the STM32F100 so I expect this to work, but haven’t tested it in hardware.
If the above configures the clock tree correctly though, the rest should pretty much work out-the-box.
Please note that the STM32F103 clock tree support is experimental, since it builds directly upon the complex work of the future SystemClock:
https://github.com/roboterclubaachen/xpcc/pull/39
Happy Holidays,
Niklas
PS: You need to provide your own OpenOCD configuration file, since I cannot know what hardware you are using.
