I cloned this repo and tried to flash my STM32F3 DIscovery board using make flash. The relevant rule is this:
flash: main.axf
openocd -f oocd.cfg -c "program main.axf verify reset" -c "shutdown"
oocd.cfg:
telnet_port 4444
gdb_port 3333
source [find board/stm32f3discovery.cfg]
make flash then gives me the following output:

** Programming Finished **
The program command shows me that no flash bank found and no data was written. Naturally, the verify command fails.
I built OpenOCD from the 0.9 tag. I installed libusb-1.0-0-dev using aptitude, which was necessary for ST-Link support.
What is wrong in my configuration, or is there an alternative to OpenOCD that I could try for this task?
It looks like you have the wrong defined FLASH address. It is flashing from address 0, and not from 0x08000000 where FLASH in STM32F3 is.
I had a short look into the GitHub repository and the problem seems to be in the linker script. In file LM4F.ld the FLASH address is defined at 0x00000000.
