[Paparazzi-devel] Black Magic Probe: Why two ttyACM* devices?

[Simon Liebold]

So far I only used the BMP to upload the firmware onto my Lisa MX using
SWD on latest master. The JTAG option never worked for me (with the
"JTAG device scan failed!" error). I never used the BMP for any
debugging - nor would I know how to do that.

But why does it create two ttyACM* devices when plugging in? Is the
other one supposed to work with the JTAG upload setting? I read that
flashing via JTAG would be much faster than via SWD. Is that correct?
