I've actually realized just now that I don't fully understand how that works
13:57
<
whitequark >
how dooes openocd choose between devices?
13:58
<
whitequark >
I can't quie find that anywhere
13:59
<
whitequark >
ok, so that needs ft2232_serial in the openocd script
14:01
<
whitequark >
I can make a symlink to /dev/bus/usb/... but it doesn't appear to be actually used anywhere
14:02
<
whitequark >
similarly with kc705, the cp2103 they are using does not have a unique serial
14:02
<
whitequark >
we can't identify it in any way except by bus topology, I think
14:23
<
rjo >
yes. it does not use the serial device or the usb device. libftdi provides its own searching.

as long as we don't hook up more than one kc705 or pipistrello we are ok ... otherwise we would have to expose ftdi_serial and/or ftdi_location through artiq_flash

the ft2232 is obsolete and not used here.

so that tests can always run undisturbed

I am running the same test, so far it is successful
