SDK Openocd stm32f4discovery.cfg is incorrect for new versions of the STM32F407G-DISC1 #7144
Description
The new versions of the STM32F4 discovery boards, STM32F407G-DISC1, have an STLINK V2A embedded on the board instead of an STLINK-V2. However the openocd script that is shipped in Zephyr-SDK-0.9.2 specifies using the stlink v2:
# This is an STM32F4 discovery board with a single STM32F407VGT6 chip.
# http://www.st.com/internet/evalboard/product/252419.jsp
source [find interface/stlink-v2.cfg]
transport select hla_swd
# increase working area to 64KB
set WORKAREASIZE 0x10000
source [find target/stm32f4x.cfg]
reset_config srst_only
Using this config causes the hello_world sample to fail when executing the flash target:
