That could be.
Recently, I flashed a LPC1751 using SWD by accident.
I changed the script, so it would use jtag.
Here's my 'Board.cfg':
---8<-----8<-----8<-----
echo "### Flashing/Board/Board.cfg"
transport select jtag
#transport select swd
source [find target/lpc1751.cfg]
# our board runs on an external crystal; we can handle 249 kHz, but will be
alright with 225:
adapter_khz 225
--->8----->8----->8-----
-I *know* this worked before I build OpenOCD 0.9.0, so I wonder if the
'transport select' handling changed somehow ?
No matter which of the "transport select" lines I enable, I get the same error:
Error: session's transport is already selected.
-But if I disable both, the board is programmed using jtag.
This is the -d3 log:
---8<-----8<-----8<-----
$ openocd -d3 -f interface/ftdi/jtag-lock-pick_tiny_2.cfg -f

Notice the "Info" line (31) tells us very early that the transport has been
auto-selected already.
In 82, I attempt to set the transport.
I'm getting the feeling that the transport is selected, as soon as the
interface is selected.
-But that theory does not sound correct to me either, because that would mean
that "transport select" would be completely broken.
