Also works when the line
hla newtap $_CHIPNAME bs -irlen 5
is commented out

Hi,
I tried to use an STLink v2 as a JTAG interface (hla_jtag) to an STM32F103 mcu
and it throws the following error:
~~~
/usr/bin/../share/openocd/scripts/target/stm32f1x.cfg:41: Error: invalid
subcommand "newtap stm32f1x bs -irlen 5"
in procedure 'script'
at file "embedded:startup.tcl", line 60
at file "/home/fabian/.openocd/stm32f103.cfg", line 11
in procedure 'jtag' called at file
"/usr/bin/../share/openocd/scripts/target/stm32f1x.cfg", line 41
~~~
I modified the file target/stm32f1x.cfg in line 40 to look like this:
~~~
if {[using_jtag]} {
if {[using_hla]} {
hla newtap $_CHIPNAME bs -irlen 5
} else {
jtag newtap $_CHIPNAME bs -irlen 5
}
}
~~~
and now works fine with the STLink v2 and jtag-lock-pick tiny v2 in swd and
jtag mode.
The other target/stm32fxx.cfg files share the same problem but I haven't tested
the modifications with real hardware.
Also note that there is an implied 'else' in line 30 of the stm32f1x.cfg file,
I think that would be nice to put an explicit else for consistency.
I'm using openocd 0.10.0 from Debian testing.
