# The STLink on the Discovery has a USB ID 0483:3744 and presents itself
|
||||||
|
# as a mass storage (i.e. SCSI) device. The SCSI emulation is signficantly
|
||||||
|
# broken, and the kernel spews error reports for a while until it is
|
||||||
|
# accepted. Further problems are encountered when if it is automatically
|
||||||
|
# mounted.
|
||||||
|
#
|
||||||
|
# Options that may prevent the mount are
|
||||||
|
# ENV{UDISKS_PRESENTATION_HIDE}:="1",
|
||||||

# ENV{UDISKS_PRESENTATION_NOPOLICY}:="1",

Setting up udev rules
|
||||||
|
=====================
|
||||||
|
|
||||||
|
For convenience, you may install udev rules file, 10-stlink.rules, located
|
||||||
|
in the root of repository. You will need to copy it to /etc/udev/rules.d,
|
||||||
|
and then either reboot or execute
|
||||||
|
$ udevadm control --reload-rules
|
||||||
|
|
||||||
|
Udev will now create a /dev/stlink file, which will point at appropriate
|
||||||
|
/dev/sgX device. Good to not accidentally start debugging your flash drive.
