the security bit is the using the str9xpec driver

so in your config you need the str9xpec driver:

flash bank str9x 0x00000000 0x00080000 0 0 0

flash bank str9x 0x00080000 0x00008000 0 0 0

flash bank str9xpec 0x00000000 0x00080000 0 0 0

# assert reset (srst)

#jtag_reset 0 1

then to lock the device

# enable turbo mode

str9xpec enable_turbo 2

# lock str9

str9xpec lock 2

# disable turbo

str9xpec disable_turbo 2

# let device run - resetting tap aswell

jtag_reset 1 1

jtag_reset 0 0

see the following for more info:

Hello,

I'm trying to set the security-bit on a STR912FAW44. I found a PDF (http://www.st.com/stonline/products/literature/pm/11659.pdf) that describes which register needs to be set but I have no idea how to do this using openOCD. I use a wiggler-compliant jtag device to program the processor.
