I'm tring to work with a STM32F030F4. Unfortunately I didn't manage to flash the application on the controller.
- I'm using openOCD with a ST-Link.
- I use the following to start openOCD: openocd.exe -f interface\stlink-v2.cfg -f target\stm32f0x.cfg
- I now use Telnet to talk to openOCD.
I do the following sequence:
Open On-Chip Debugger
> halt
target halted due to debug-request, current mode: Handler HardFault
xPSR: 0xc1000003 pc: 0xfffffffe msp: 0xffffffd8

It seems that everything is fine as the communication with the chip works fine. Never the less I can't flash my application on the chip.
What could be the reason for that?
Could there be something missing on the hardware?
I'm using a selfmade board with:
- VDD and VDDA connected directly.
- Rst connected to a RC with 10k and 100nF
- Boot is connected directly to GND
- No external cristal
This are the Optionregister: 0x1ffff800: 00ff55aa 00ff00ff 00ff00ff 00ff00ff ffffffff ffffffff ffffffff ffffffff
This is the factory setting!
Thanks,
