I'm having trouble booting my project and would appreciate some help. I have had success in the past with F0 and F1 parts, but am having some trouble with the F2.
The board is custom, based on STM32F205RGT6 using the STLinkV2-1/SWD from a Nucleo board. I can successfully flash and debug bare metal code using the defaults in SW4STM32 (openocd), so I know the hardware is OK. I setup a ChibiOS 16.1.5 project, based on RT-STM32F207-DISCOVERY demo project, except with the mcu type define changed to STM32F205xx, and pins set as inputs to avoid contention. I can compile/link no problem.
When I download and attempt to debug (using texane/st-util and gdb, a combination that works for me with an F0 part), I get the following output:
Code: Select all
cmerck@klendathu:~/src/xanthos/firmware/RT-STM32F207-DISCOVERY$ sudo ./debug.stlink.sh -f

make: Nothing to be done for `all'.

The line which stands out to me is:
Code: Select all
0x1fff3de4 in ?? ()The fact that I can download & debug a bare metal project in SW4STM32 leads me to believe this is a software issue. My OS is Ubuntu 14.04 LTS if that matters.
Thanks for any pointers.
