[RCC] The original document was wrong - I posted an update.

[RCC] This is what you would expect.

[RCC] Sounds like you may have a Tcl/Tk compatibility issue here. What
version of Tcl/Tk are you using? On what platform? What version of Insight
are you using?

You can always use the console and enter the gdb commands explicitly:

(gdb) target remote localhost:2000
(gdb) load
(gdb) break cyg_user_start
(gdb) cont

[RCC] This is needed for the UART output with the specified command line,
however you can send the UART output to the console by changing the --board
option in the SID command line to:

--board=pid7t-normalmap-uart1:stdio

If you do this you don't need the --tksm option.

AFAICT (by looking at configrun-sid), other options for where to send the
UART output include gdb, a socket or the serial port on the PC. If you want
the output to a file, I guess the easiest way is to use the stdio option
specified above and redirect stdout, or pipe to tee <file>.
