mksnanov3: limit programming speed to 1800 kHz
Both of my development boards exhibit stability problems when
programming at the default 4000 kHz speed of the target/stmf32d4x
OpenOCD configuration.
Note that the speed limit must be set by an event handler, because it
is hard-coded by a similar event handler in stmf32f4x.cfg:
$_TARGETNAME configure -event reset-init {
# Configure PLL to boost clock to HSI x 4 (64 MHz)
...
# Boost JTAG frequency
adapter speed 8000 <-- resolves to 4000 kHz by the SWD interface
}
While here, replace the reference to the deprecated "stlink-v2"
configuration.
